CPE EMS Problem???

[Finkle]

Alrite the install was a pain in the ass but worth it. i will have some pics up soon.
So i havent had a chance to tune the car yet, looking for a dyno shop that wants less than 200/hr. But running the car on the bas map at 15psi it feels really good, havent had the chance to see what the higher rpm are really doin( well havent driven it hard yet). She runs pretty good, now heres where im getting a problem, when i switch over to 17psi

I was on the hi-way, at about 4500rpm and noticed my boost gauge drop and the car had a little hesitation to it so i backed off. I thought it was just me so i tried again, but this time i tried a sweep at wide open throttle in 4th gear from about 2000rpm to about 4500, now when i hit 4500 this time, my car had a nasty backfire????wtf is up with that (nailbyt) at this time i also happened to look down at my dash and noticed that the light with the car and swiggly lines was flashing ( my traction lite) why and how?

I havent even taken it that high again with 17psi; 15psi seems okay but imma re-check everything before i try anything again

Now the second problem im having, my car is requiring me to crank a bit longer now, if i crank it my old normal time the car will stutter as it starts, what might this be?
i guess imma start by checkin every single connection all over again and meter it again, or is this my tune?

[Finkle]

ALSO SUX that CP-E is at sema all week, so NO support :(

u cant just start raising the boost up ,the car is running lean, do urself a favor and take the cpe off till you have the money to tune it, the base tune is just that. a base tune. is its tune to that 15psi, and the problem is the car is getting a lot efficient due to colder weather.

[knowledge007]

Yes you can run 17 with no problem. the car is not running to lean Ade, we run rich as hell stock anyway. As for the problem starting the car, yes you have to pause on the on position due to the fact that the unit has to do atleast one loop before you crank. Remember that you have installed and aftermarket part that is being powered by the stock battery. Therefore the has to be powered and looped at least once in order to send all the signals to crank the car.

As for the stuttering @ 17 psi. I don't really know what that is. I have no problems dogging this beast of mine @ 17 psi all the way close to red line. That could be fuel cut but then who knows. Or you could have tapped into a wrong wire.

No CEL's yet? Did you run the bypass valve before you actually ran with the unit?

[Finkle]

My turbo seals may be gone, i heard a rumor that the oil could be causing my car to detonate
Ill put my wideband in 2morrow hopefully and see what shes running at, for the time being ill put the bypass plug in
thx

[knowledge007]

Its not the seals trust me. That has nothing to do with it. Check your wiring and and double check. Disconnect the negative battery cable and plug the bypass on and run with that for a day or two. If you have any more questions please feel free to post or pm me.

Finkle read my last as I edited it.

[Finkle]

yea imma double check all my wiring and go form there
one question i have when metering the wires is the list pin 20 as black/brown stripe, well pin20 is purple and i cant find tthis black n brown wire, is that a typo in the instructions or am i dumb, it says it should metere at .2volts, mine meters at .3
imma check that wire and pin 11 the green its metering at .31 when it should be about .2
those may be my problems right there

How would i be hitting fuel cut?

[knowledge007]

You should have 2 wires crimped off that you are not using at this time. Is this correct? The black and brown and black and red I believe???

[Finkle]

Yes that is right

[knowledge007]

Then I have a feeling you are looking at the cp-e connector backwards??? I can only check for you when I get home. I should be home in couple of hours as my instruction are at home.

[Finkle]

No, im reading it right off the instructions, in the section where it tells u to check the volts of the wires
For some reason in this section they say pin 20 is black brown with and expection of about .2 volts
but pin 20 is purple, when u actually install the wires it says pin 20 purple, tap into wire 2BA

i hate being stumped, damn sema show, i cant even talk to anyone at cpe

[knowledge007]

Don't worry, I will check with you when I get home. You said you soldered the connections right?

[Finkle]

Yup i soldered all my connections, imma have to rechekc them all to see if thats the problems, maybe something wasnt done right....just gotta wait for the boss to leave then i can pull my car into the bay and rip it apart and go from there

[MS3TR]

Yeah you probably have a wiring issue and you also really need to get it tuned. My shop tuned my car at 19psi and it runs beautifully without a single problem. He did nearly 30 pulls to get this map running smooth and safely but it pulls like mad now(dance). The tuning can be expensive if you don't know anyone personally but its well worth it regardless. Not only will you make more power but you will also be doing this safely. Good luck!

[Captain KRM P5]

no offense, but no one has any business street tuning a fuel map on any engine management system without a wideband to measure your air/fuel ratio. a base map, regardless of how good it is, regardless of what EMS you use, is just a base map. every region, every altitude, every climate is going to require fine tuning period to get optimum results. tuning or installing an EMS without a wideband is akin to installing a boost controller without having a boost gauge.

[Sierra117]

tuning or installing an EMS without a wideband is akin to installing a boost controller without having a boost gauge.

But that takes all of the fun out of it. Shot in the dark tuning is where its at(naughty)

[Finkle]

yea my wideband is coming in tonite and should be in 2morrow
To anyone who wants to kno here are my volt measurments
Pin # Wire Colour Expected Measurment Measument
1 gray 10-14 volts 11.93
5 white/black stripe .61/.80 volts .61
6 white/brown stripe 0.5-4 volts 2.11
8 orange apprx .2 volts .3
now the problem im having with this wire pin 8
sometimes it will read about 4.9 volts and then sometimes it will read .3, ive checked the connection several times, nothin wrong at all
10 red 10-14.5 volts 12.3
11 green apprx .2 volts .3
same problem with this one pin11, it goes to 4.9 when pin8 is not reading right
but when one is reading right they both are
13 white 1.1 volts .96
14 yellow 1.87 1.91
15 red/white stripe .61 .62
16 blue 1.87 1.91
17 orange/red stripe .5-4volts 1.91
20 black/brown stripe .2 .32
pin 20 is purple tho typo in the instructions?????

what u guys think that HAVE an cp-e ems

[Finkle]

the chart didnt work out as expected, i can pm someone a better one if u cant understand it

[desperado-c]

So, it's not fuel cut caused by running the catless DP at 17 PSI? I thought there were a number of people having this problem already.

[Finkle]

Really, i never knew ppl were experiencing fuel cut cuz of the downpipe....i guess imma have to suck it up till i get my wideband in. then hopefully sopmeone at cp-e will be back lol, hopefully they are enjoying sema

[laloosh]

i should not be experiencing fuel cut. In the boost settings, under advance boost your boost clip is set to 13 psi. Meaning your map only sees 13psi.
Do you have a aftermarket bpv? CAuse mine did this before and after the standback. I put the stock valve back on and all my problems went away. Theres dones of poeple complaining about the stutter/backfire issues at high rpms in the cold weather.

[Finkle]

stock bpv, i think the cold weather may have a lot to do with it, but hopefully i will be able to see everything when data loggin, and with the wideband
i dont even wanna try 17psi yet without my wideband

[knowledge007]

Don't be scared I ran 17 with no problem. The data logging is cool as shit... I basically bought the EMS just change boost as I please...

[Craighjr]

what u guys think that HAVE an cp-e ems


Exact same here. I talked to Jordan about some unrelated celo issues. The 5v on those wires I never checked into. Pin 20 is puple though the chart says onterwise, pins 18 and 19 are unused and the brown wire isn't connected either.

[Finkle]

yea thats where i was, i gotta talk to jordan myself, and see what he says about the 5volts i wonder why the car is doin that.
maybe thats whats causing my backfire.......
should i try and go to 17psi or just leave it till i talk to jordan

[x'ed]

Just a thought, maybe it's different pin set up on the mazdaspeed 6 and the standback was designed for that. I don't have any idea, just a shot in the dark.

[Craighjr]

Just a thought, maybe it's different pin set up on the mazdaspeed 6 and the standback was designed for that. I don't have any idea, just a shot in the dark.

No the speed 6 has a 100% different pcm. I would run 15 till jordan gets back to you. I didn't even install the switch for 17 in mine yet. Figured no reason to tempt it while untuned. I am having lean codes 2177 or 2187. I am vta but the bov should make it rich??? I may go back to recirculate and 0 maf correction to see what the hell is up. I am a few hours away from CP-E but they don't tune cars. I was mega bummed about that. I am going to talk to them and see who the recommend to tune their stuff.

[Finkle]

i have a cel light but i think its for the cat not being in, well thats what it was before the ems install....i go in saturday to find out exactly what the cel light is about, hopefully its all o2 sensors

your lean codes are caused by ure vta. Let me know when ure going to get tunning done. Im from jersey as well, we should go together.

[Finkle]

got my codes puleed and came up with
P0139 - which is my rear o2 sensor (o well)
P0107 - map sensor circuit low input
P0245 - boost soliniod

the tech thinks that the last 2 codes arew from the car starting up without the ems loading up, so far ive been lettin the car sit in the on position for 5 secs b4 starting and no cel's for me :D

One one-thousand, two one-thousand, three one-thousand, four one-thousand, five one-thousand. You know, I don't think I'm always gonna have time for that in the heat of a given moment. I hope CP-E comes up with a fix.

[Craighjr]

I don't know about that. The standback works fine for me when I just fire it right up. Maybe try to go back to stockish to figure it out. Does your car run well with the bypass plug on? Mine runs fine then, but pulls lean codes with the standback hooked up, VTA and a MS CAI.

Thats funny, I was getting a the po107, p0102 low circuit inputs. Also got a p0300 - random cylinder misfires detected. If your getting the same then it is the standback. Now I feel like an idiot for taking it out... Kept insisting that I cut a wrong wire but I checked over a 100 times and everything is correct. I see now what you are talking about Finkle about the typo. Yes pin 20 is purple. Let me know what you Jordan has to say about your problem Please!!!

Another thing, I crimped and you soldered and your getting the same issues...

[knowledge007]

I ran the bypass with my setup for quite some time and had no issues. Thats why I am so bummed. Only had issues with the standback installed.

[laloosh]

mine runs fine...i dont need to wait 5 seconds, i just jump in and fire it up.

[knowledge007]

With the bypass, it would crank right up with no problem... Did you uninstall the fuel cut defender for the EMS?

[laloosh]

yea the fcd and mbc are sold

[knowledge007]

Thats what I thought. Was just glancing at your sig...

[laloosh]

Yea sorry about that. My sig is updated now. My ems runs fine, doesnt take a while to start up, no cels, no wierd issues. Just 17psi of pleasure lol. I didnt solder anything in, i just twisted all the wires exactly how cpe described in the how to.

[knowledge007]

Thats fucked up man, now I am really bummed... I miss you 17 psi so much. I don't understand why some have these issues and then some don't. What gives?

[laloosh]

did u always have these issues? Or did they just appear. What exactly are the issues cause i must have missed the thread/post

[knowledge007]

What do you mean always? With the standback or before? Before the standback I had no issues. Only with the standback. Basically the issues never caused anything in particular, just what Finkle is getting the low circuit inputs and random multiple cylinder misfires. I just didn't like that fact that that fucking CEL was on. Other than that the car ran great, all data logging was correct...

[laloosh]

what are the issues u are having with the standback?

[knowledge007]

Um, what I said in post 33 and 42. The only real issue was that 3 to 5 second delay I had to wait before I cranked. But still got the CEL's... At the moment I have removed the standback. Going to wait for the PNP connectors.

[Finkle]

If i wait the 3-5 seconds i have NO CEL's at all, i dunno maybe mine being a canadian model or being right a sea level is making a difference
i dunno im stumped but im still running it at 15psi with no problems imma try 17psi in abit and see how it goes

[blkMS3]

my boy just installed mine at first he had the same problem w/ the red and orange wire reading 4.9 or 5 volts and going back to .2 after a lil bit....so we started it and it fired right up i have it running at 17 pounds and it feels fast as hell....

[Finkle]

i finially got some runs in last nite, my frinds family owns a ton of property with a 3mi long road at one end of the property. Well i have no problems with the car at all, on either 15 or 17psi, but as soon as i hit wide open throttle in 4th gear, the car would hiccup and backfire at about 4500rpm
now i beleive that has something to do with those wires not reading the right voltage

nope...nothing with the wires. Its something with these cars with cold weather. My car did this before the ems with a aftermarket bpv. with the stocker it doesnt do it.

[Finkle]

it only does this with the cp-e plugged in, i dont understand, the only thing i can do is wait for the wideband which has been elayed till monday
i hope everyone at cp-e is back monday

[laloosh]

it does it cause ure running/holding more boost. Nothing with the cpe unit is flawed. My car started doing this with i/tbe/bpv. At around 4500 you feel it slowing down and then it stutters, as if the car misfires, then comes back alive, then stutters ever 300rpm or so.

[Finkle]

yes, now why is it doing that?
thats not normal

[laloosh]

if u figure it out let me know.
My guess is the fuel pump/maf sensor being maxed out with cold weather.

[knowledge007]

Never had that problem before??? My car runs like hell. Although I do get an occasional backfire when switch fast. Even withouth the ems I still get back fires but no hiccups just huals ass...

[laloosh]

for me this only happens in cold weather and with the forge bpv on.

[Finkle]

im started to get get quite disappointed with this ems
but hopefully a tune will fix this, but if the maf is maxed out then im shit outta luck
now i really wanna get a hole of cpe

[laloosh]

yea i was disappointed with the base maps lol. ITs a 2 psi boost and everybody says its god. Like i said i dont see myself gaining any serious power with tunning like people here think. All the gain will be from boost, and then u run out of fuel...the end.

[knowledge007]

Keep me posted Finkle as I have already taken the ems out but would like to know what Jordan has to say. Anyhow, I will be waiting for the PNP connectors as I have already soldered everything back to its original state.

[Finkle]

im almost ready to solder everything back, i dont understand how the pnp will be any better, its gonna be a base tune as well, and you wont be able to alter the tune. If im running outta fuel or even experiencing fuel cut what makes me think that the pnp will be any better.
I just tried calling p-e looks like they wont be in till monday either way :(

[knowledge007]

Remember Finkle you have to tune the car at a tuner of your choice. I primarily picked it up for the boost and thats about it. I have everything else from CP-E except the FMIC. I was going to get the tune done sometime in the next century, but hey what the hell. I know what you mean by the PNP but at least I won't be cutting anything anymore. I don't and will never do that again. I will always wait for PNP.

[Finkle]

yea thats tru, so what did u do with ems knowledge? its not just a paperweight is it?

[knowledge007]

No, lmao its nicely stored in my closet awaiting for the PNP connectors from CP-E...

[blkMS3]

I haven't had any problems w/ my car yet....i installed it on friday and have driven about 200 miles and the car feels real fast i can def. tell the difference in the butt dyno....

[Finkle]

bLKMS3, whats the temperture like over there? up here we're sitting between 5 degrees celcius - 15 degrees celcius

[Finkle]

K, i finially talked to jordan and started working my issuses out.
First question was: flucuating voltes in Pin 8, he actually said that was normal because it is a crank position sensor, so depending on where the crank is, is what your reading is gonna tell you.

Sencond q: Why is my car experiencing a hiccup (or fuel cut) and he confirmed my nightmare. ITS FUEL CUT from what he can gather, cuz im only getting it at wide open throttle.
Now my fix for this:
first thing he told me to do was, in the standback programmer, go into the Advanced Boost Controller Settings and change my Boost Clip PSI from 13.0 -10.0
Next thing: was to do some live data logging via a passenger in the car so the driver can concentrate on driving. What he said to do was watch my fuel trim cell, and watch where i was getting my fuel cut. Then to change some values in my fuel tables to try and subsidize for the fuel cut, and HOPEFULLY this will give me a temporary solution till i get it on the dyno.

[laloosh]

I spoke to jordan as well. So far ive put my forge back on. Reduced the boost clip from 13 to 10. And added 3 percent of fuel in the midrange. Went out for a test drive, floored it in 3-5th and it ran great. Than again it was 54 degrees outside. Ill try this again later at night when its sub 40 and well c if the problem is solved.

[Finkle]

Awesome work Laloosh, imma try that tonite when the temperture is down to 5 degrees celcuis
Now when you say you added 3 percent of fuel to the midrange what do u mean....did u change the 0's to 3's in the midrange? and if so where did u start and end, just so i have something to compare to

[laloosh]

yea i just replaced the zero swith 3s. I started at everything to the right of 2.1 ranging from 2897rpm to 4345 rpm. If this doesnt make sense, just open the software and it will make sense.

[Finkle]

makes perfect sense but why did u stop at 4345?
do u have a wideband hooked up?

[laloosh]

ive just based it on maybe dynoes that ive seen. This car runs lean down low and in the mid range and stupid rich up top. Plus my lil hicup occurs right around 4200rpm so im dumping more fuel at the point, it "should" go away. Im going to go out later tonight and do some datalogging to see if it happens again...if it does ill be able to see the exact rpm, and ill dump more fuel to that spot. If it continues to happen, then i give up.

[Finkle]

PERFECT, ill do some data logging myself tonite, and we'll compare notes

[Jays07MS3]

makes perfect sense but why did u stop at 4345?
do u have a wideband hooked up?

Correct me if I'm wrong but can't the standback read the stock WB sensor? The product description doesn't mention it specifically but it say is can read just about every sensor. If so, can't you log the sensor readings and tune based off of that?

Our StandbackTM can also datalog just about every engine sensor for up to 40 minutes (depending on the selected sample rate of either 5, 10, or 20Hz)! This is an invaluable tool for diagnosing tuning problems as well as for monitoring engine health. Welcome to advanced engine tuning in the 21st century!

[laloosh]

it doesnt pick up my stock o2 sensors....ive tried

[Jays07MS3]

it doesnt pick up my stock o2 sensors....ive tried

Thats lame. :(

Hopefully that something CPE can add in a future update. I don't know why they wouldn't be able to read them. Does the standback have the ability to read auxiliary inputs such as WB 02 or EGT?

[laloosh]

it does, but who knows how to hook them up. i think cpe mentioned that they are gonna have their own wideband available that connects to the ems. I thought it would pick up the stock o2 as well. This way i can just street tune it and forget about it.

[Finkle]

No it doesnt pick up the stock wb, ive tried several times. I guess if it picked up the stock one they wouldnt be able to sell an aftermarket one.

Where did u pass the usb connector through, the hood release hole is too small, did u drill antoher one?

[laloosh]

i just ghetto rigged it for now through the fender and out by where the door hinge is.

So i did some datalogging but im not sure how to actually get a graph of it. Neway i went to the extreme and just dumped 10 percent more fuel from 3-7k rpm and holy shit the car just instantly drove 10 times worse, it hit fuel cut and bogged and went and bogged and went. It was horrible. When i actually leaned it out a lil 2-3 percent the car pulled HARD. Once again the temps is 49 degrees and i didnt get any hesitation.

Now heres my theory, by adding fuel two things are happening.
1. Its just flooding the cylinders and making it studder cause its so rich
2. Its making out the pump trying to add the fuel i requested.

This who datalogging thing is USLESS without a wideband and im done with it.

[Craighjr]

Hey sorry I've been busy and dropped off the thread. I have to get surgery on my wrist Friday so I'm out of comission for a week or two. I'll try to get my wide band in this week and then as soon as I feel a bit better I can start tuning. I'll probably bring it to IMP and see what they can do also, that and to get solid numbers at the wheels. Just as a side note you really want to lean the car out I think. They run pig rich already around 10:1 so if you bring that up to 12:1 your leaner but still quite rich.

[laloosh]

fill me in on ure imp visit. I might wanna go as well.

[Finkle]

I didnt get a chance to make it out but on my way from work i did change a few things before i left, but just upped some of my 0' to 2's and it didnt get fuel cut or backfire, so imma try and push her in the morning and find out.
Where did u end up leaving your values for fuel?

[nypest]

My turbo seals may be gone, i heard a rumor that the oil could be causing my car to detonate
Ill put my wideband in 2morrow hopefully and see what shes running at, for the time being ill put the bypass plug in
thx

Oil causin denotation??

[staples187]

For those that care, the PnP system for the standback is two months from development and it's going to cost about 400. The people that are having problems soldering and crimping their connections may want to just save the time and frustration and wait for the plug and play. CP-E is also going to give out tune maps like candy to those that email them when the harness arrives.

... I'll wait (wiggle)

[Finkle]

Yea i've worked all my kinks out, and now she pulls hard like crazy.
Cp-e a;ready said they would help me out with the maps, but the map that comes with the pnp is still gonna be base map like they are giving with the standback
i can get a million base maps from them, but my car may never run right till i get a proper tune

[Powerslave]

No, lmao its nicely stored in my closet awaiting for the PNP connectors from CP-E...

Hey if your having issues why don't you send ther unit back, I was having similar issues with mine i just sent it back to have it checked out

[Powerslave]

fill me in on ure imp visit. I might wanna go as well.

dude kinda new to the forums, been checken you out on youtube and the forums you are a BADASS driver!!(lol2) I got the standback too but im haveing some issues with it right now

Only 400 bucks? Nice. The bcd and boost controller will hold me over for two months, then its time to go evo hunting (evil)

lol, just kidding, don't advocate street racing, but 300+ whp will be nice to have on tap. Now, if only someone could find out how to attach the awd system from the ms6..........

[laloosh]

well i fucked it some last night, it was only 49 degrees and the car pulled like this

http://www.youtube.com/watch?v=k6GmgPz7A6g

no fuel cut to be found. Tonight will be in the high 30s so well c how long this works for.

[Powerslave]

seem to run good! it seems like the exhuast is louder with the stand back i have my bypass plugged in and the exhuast doesn't seem as loud. I like it loud and mean sounding

[knowledge007]

Hey if your having issues why don't you send ther unit back, I was having similar issues with mine i just sent it back to have it checked out


I am way ahead of you my forum friend. Like I said, waiting for the pnp connectors.

[Powerslave]

I am way ahead of you my forum friend. Like I said, waiting for the pnp connectors.

if your just waiting for pnp thats cool, but just to clarify when you say your way ahead of me do you mean you already sent it in and they can't fix it? Mine was running really funny all the sudden, especcially in the morning when the engine was cold it would idle reeeal loud and it would misfire and then the check engine light would come on. As soon as i pluged in the bypass no problem and cel went off.

[Finkle]

Well i got my wideband in the mail today, and the exhaust shop is puttin it in as we speak. SO imma start doin some tuning today, and see where she goes
NICE run laloosh, hopefully ill get mine to run as good without a proper tune

[knowledge007]

dude kinda new to the forums, been checken you out on youtube and the forums you are a BADASS driver!!(lol2) I got the standback too but im haveing some issues with it right now


Its the case I must be a Grand Master....j/k Drives like a driver should. Should see my vids without the ems. jubanqt on youtube if you would like to see and here. Nothing but vids of my 3.

back on topic guys i don't want to have to dump this thread cuase it ended up in a discussion about street racing...

[Powerslave]

whoops!! lol, this topic is important to me cuase i'm having some issues so please don't close it, thanks!!

[Finkle]

I just got my wideband in today, sorry to re-ask
but whats optimal a/f ratio for our cars?

[griffeyfan25]

Hey guys I have a question. I have the cp-e TBE, injen Cai and I just recently installed the standback yesterday actually. Let me say when I first took my car for a drive after I had it installed I could really feel the boost in first and second gear but thats not my problem. I can't figure out how to raise the boost. I broke one of the pins off of that switch and I cant plug it into the cp-e harness now and was wandering if there is a way around this because I cannot switch between maps. Also I am guessing my car is set for the primary map and when I tried to turn the boost up on the primary map and send it to the controller it said boost sent and verified but my boost gauge is still reading 15 lbs like before. I dont understand why I cannot up the boost. Any suggestions on what I could do. Also my car doesnt hit full boost til like 4k rpm. Like if i start at like 4th gear at 2500 rpms I dont hit 15 psi till late 3000's early 4000's rpms. Is this normal because the boost kinda climbs. I believe A good afr reading is anything between 10 and 12. Mine is 11.5 and jordon from cp-e said that is good and that is at full throttle.

Zac

[Powerslave]

in the firs few gears even with the 17 psi map you won't get full 17 psi cuase the throttlle plate is still tryeing to close, in third i got got 16 psi and in 4rth 5th and 6thi got 17 to 18 cuase youll get get moor boost at lower rpm's in higher gears do to load.. wich is also not good for your engine

[Powerslave]

got the standbck updated, car is running GREAT!!!!!

[Powerslave]

i sure did miss good old 17 psi map plus holding boos past 6,000 is reeeeeally cool. now i just need to get it tuned.

[Powerslave]

man i need new tires i have al most no traction in first or second when i floor it, this thing rippes tarmac at 17psi!!!(drinks)(10)(drive)

[MS3TR]

Yeah the CPE Standback is awesome! I got mine running off of a basically stock map and one tuned to hold 19psi with a 12:1 ratio. It pulls so much harder than before, I love it! I had a CEL come up due to it running lean at idle but it was easily adjusted by my tuner. Jordan from CPE just gave him some great instructions on bumping up the MAF voltage up 1% and so far its perfect. It never ran rough or with any problems but I just didn't want the CEL on for dealer visits.

[Finkle]

the tuning shop i want to go to has a 2 months waiting list, so right now its tuned to what i think is good lol, my air fuel hovers around 14 at idle and while driving anywhere from 13-14.6 i was gonna make it a bit more rich but oh well......15psi is good enough for me right now, gonna try and tune 18psi as soon as the weather holds up

[Craighjr]

What are you running A/F at wide open throttle tho. Over a certain tps angle the computer says screw emmisions I want power and then you should be more like 10:1-12:1.

yeah I had the same cel too lean at ilde its cuase the cold wheather its no big deal and they have quick fix mine is gone. Car was running perfect even when it was on. I can't wait to get mine tuned!

[Finkle]

Its Started snowing here, looks like imma have to put the car away for the winter.....the tune will come EARLY SPRING with maybe a new mainfold :D

[Powerslave]

that sucks about the snow although it is nice for christmas and stuff, yeah 4whd is a advantage for the evo and sti. But they also cost alot more for around the same performance and power save the awd. Plus the ms3 has a nicer interior. I'm getting a tune as soon as i save some money, no snow down here.

[Craighjr]

I got the snow this morning as well but it should be 50 and 60 the next two days. Im still torn on tuning this year or not. I have a check engine lamp for a lean code either off idle or at idle. The standback can only use the maf xf to fix that so that will throw off the tune once its done I imagine. I may just tune it this week anyway as I'm bored as hell not working. Hopefully Jordan will e-mail me back with a few solutions or something.

[Powerslave]

dude I got the same thing "too lean at idle" code its no big deal, the cold weather just throwes the fuel trims just outside the acceptable range with the standback. Jordan has a simple e-mail map fix that add a touch mor fuel at idle or I think you can slightly increase the maf voltage. It doesn't hurt the car mine went off byitself.

"no big deal" but mine will not go away. The ms intake and stanback both lean the mixture out so I'm still waiting on a fix to work.

[Powerslave]

you could just get thier intake, I know 300 bucks though kinda sucks

[Craighjr]

you could just get thier intake, I know 300 bucks though kinda sucks

I upped the scalar on the maf xf to 2 around idle to hopefully fix the P2187. Then I sloped it down from 1.5 to .50 from the off idle to 3.9 volts to keep the P2177 from coming back. If this doesn't work I will put on the stock air box for testing sake. I have thought of switching to a CP-E intake if necessary.

[Finkle]

well looks like imma have to def. put the tune off for the time being
i WANT that manifold

[sp33d 3]

does anyone know how to get rid of the cel P0102? i'm switching to the cp-e cai this weekend but i doubt that will change anything... i've been running the bypass because the chip has violent fuel cut at 3000rpm and 4500rpm

and finkle are you from the gta by any chance?

[Finkle]

No im not from gta

i had that very code as well. What mods do u have?
check to see if the mass air flow is plugged in, if it is plugged in
u can pull it out and clean it with a q-tip ( it may be dirty)

are u running a standback??

[sp33d 3]

i have the cp-e full turbo back system, mazdaspeed cai, forge bov and im running the bypass plug because of the fuelcut when the standback is connected... i've already tuned it, paid 7bills(so pretty much 1400 in total) for it yet it didnt resolve any of the problems... i'll have to check about the mass air flow though, but will this reduce the fuel cut? i've been on the phone with jordan and he has given instructions to reduce it but not get rid of it completely

[laloosh]

well that officially sucks. Tell you what, put ure stock bpv on and ure fuel cut will go away.

[knowledge007]

I never have experienced fuel cut...???

[laloosh]

move to a place thats cold.

[sp33d 3]

move to a place thats cold.


i was getting fuel cut in the summer as well where temp is around 25-35 degrees celcius


i'll give this a try tomorrow and see if it works

[udontknowjack]

i dont know if the problem i have is the same with the one u guys talking about....im getting mad hiccups/stumble.....=( same problem like sp33d 3

[Craighjr]

Did you get your fuel pump yet? I am untuned and when I can keep my check engine light off the car pulls fine at 15psi with no cut out.

[staples187]

move to a place thats cold.

Yeah I was getting fuel cut last night in 4th gear at around 5k, it was about 40F out.

[laloosh]

according to PG my pump should be here tomorrow. Yea i dont have any cels, i just have the stupid studdering.

[knowledge007]

Its all news to me, running at 17 the ems I wasn't getting no fuel cut no stumbling, nothing. Car pulled like hell. the only thing I got with the ems were CEL's for low circuit inputs...??? Just strange to me that all of us are expriencing different situations.

[udontknowjack]

did you solder your wiring?

sending it back doesnt really help... i dont think its a problem with the units, i sent mine back and they said nothing was wrong with it... my bov is a recirculating valve so i dont know how it causes the fuel cut

I soildered my wires, mines running fine the only problem I had was the "to lean at idle"code from having a different cia and the cold weather, I got the standback updated too and it starts eisier now, and no problems, car runs great at 17psi

[laloosh]

my studdering was happening before the ems. Everybody who thinks they know something kept saying you need a tune you need a tune, its your mbc thats causing this. 600 dollars later, its studdering with the only answer being "the car doesnt liek cold weather" Hopefully the fuel pump solves this, it got backtracked with the holidays and should be here monday. If it solves it, ill try running it with the bypass plug, if it works then i might take off the cpe unit and sell it for now.....wait for something else to come along. Then again well c what happens once cpe releases all these updates on their standback.

Is there an update to fix the long cranking. I have noticed that with my standback installed. I haven't heard back from Jordan in a while now so I will call next week.

[laloosh]

Stuttering G O N E.
btw i do not understand this car. it does the opposite of logic.

When its cold, cars run leaner.
When you modify the intake/exhaust, cars run leaner.

So ok its 26 degrees outside, my car only stutters when its cold. i went to datalog some runs. Sure enough 4k rpm begins to stutter and doesnt slow down till 6k. ok i got that on file. next i go to the extreme and add 8 percent of fuel after 3k rpm till redline. i get on it, 4k rpm BOOOOOM it felt like some1 slammed the brakes hard. my friend was following me and called me instantly saying that i might have lost my bumper in the fireball i shot out. So i try it again, same exact result. VIOLENT boost/fuel cut. So im like ok this makes ZERO sense, so i lean the car out -2 after 4k rpm. i have NEVER felt this car pull harder in my life. now im going to list all the things that make ZERO SENSE.

1. only happens in cold weather. Cold weather equals leaner conditions
2. only happens witht he forge bpv. Stock one leaks and doesnt hold boost.
a leaking bpv richens the car, not leans it out. wtf
3. how is my car running richer then stock after i/tbe?
4. this car is gay....but quick as hell now
5. i have a headace and can't believe leaning it out solved all my problems.
6. i feel stupid for spending money ona fuel pump

[tru-boost]

did you lean it out with the forge on ?? if so maybe the forge is whats leaking. if your bov leaks you will run a little rich. hhmmm maybe i wont buy that fuel pump !! i just want to buy a MBC and run 18 psi with my current mod list + a new TMIC and CBE. i guess i can alway dyno with the mods and see if it is lean or not and take it from there.

[laloosh]

no the stock one leaks, it doesnt hold boost like the forge. Im telling you my car makes ZERO sense.

[tru-boost]

well, at least the you know the valve you spent $$$ on wasnt a waste !
is your fuel pump on now ??

[laloosh]

no stupid thanksgiving delayed the shipping.

[tru-boost]

damn those pilgrims !!

[sp33d 3]

i experienced very minor fuel cut yesterday, not enough to release the pedal during accelleration... but this is with the bypass plug in and the chip sitting beside me in the car not hooked up... another thing that was quite weird is that the boost is spiking at 23 and holding at 18 psi, again with the bypass plug in and not the chip, is this normal? i thought its supposed to be 15psi stock?

If you have an intake downpipe exhaust no cats the car will spool alot fatser and spike the boost badly.

[laloosh]

my car doesnt even hold 18 and my boost is raised lol. Thats odd.

[Rock]

Laloosh I noticed you were shifting @ redline in your videos.
Most people were saying that our powerband drops off past 6k rpm and the turbo runs out of steam(and dynos seem to support this). Is it the Standback that's allowing you to utilize the entire rpm band due to being able to modify the stock fuel map or what?

Thanks in Advance.

[laloosh]

yea the standback holds boost till about 6400, i shift around 6200-6300 at the track

[sp33d 3]

my car doesnt even hold 18 and my boost is raised lol. Thats odd.

yea my car trips me out... i have a cat though, i think when the chip was originally installed it messed around with the computer and stayed like that, i dont know if its the exhaust but there are times i can smell raw gas and sometimes it comes out of the vents... i haven't done the reflash yet so this will probably be solved with it

[knowledge007]

Hey laloosh, tell me again what are you running as far as your BPV. The forge or stock? I went to atmosphere with my HKS but have been noticing some popping more than usuall. And it also seems like the engine is a little stressed. Thinking of going back to the stock for a little bit.

Sorry not to thread jack but just really curious.

[laloosh]

forge

[knowledge007]

I going back to stock for alittle bit see if it helps. It if does I will sell the HKS and get the forge.

[udontknowjack]

i did vta on my hks bov for 2 weeks....same thing with poppin alot more....go back to recirc...and its all fine now...

[sp33d 3]

laloosh if youre using the forge do you experience fuel cut with the ems?

[mike8748]

I have experienced boost cut too.
I was thinking it was fuel cut but after talking to a friend I am sure it is boost cut.
I have experienced it twice.
1.) Racing an IS08 from a stop light.
Shifting hard either in 2nd or 3rd BAM! Slammed me forward then I slammed it into the next gear and hit the throttle again and then was off again.
I still pulled ahead but then backed off at 90mph then he flew by thinking he just took me.

Mods: Stock intercooler, Forge BPV, COBB SRI

2.) I was turning right from a red light, there was on coming traffic so I got up on it, this time I was in 1st about to go to 2nd then Bam! slamming me forward.
I was like holy Sh!%! what the crap!

Mods: ETS 3.5 TMIC, Forge BPV, COBB SRI, SU Boost Tubes

This never happened to me when I had the stock BPV installed.
I thought, I'll change the spring from blue to yellow.
The car was too lag so I put the blue spring back in.

I would like to know what BPV/BOV other people are using at the time of their Boost Cut experiences.
