E-manage? Look at this FAQ

[azian6er]

http://www.mohdparts.com/emanage/EmanageFAQ.htm

This guys seems pretty confident that the e-manage is universal. Now i know our ecu is shit when it comes to tuning, but i also looked up the trust website in Japan and i saw the FS series engine listed as compatible with the e-manage. Then again, this could be an issue of FS"ZE" versus FS"DE".

I hope this shit can work because it just seems like it is this hurdle i cant get over in modding my car.

I can talk to greddy for you to see if it works.

[spoolinmp3]

We are currently developing a emanage package that will work for the P5/ MSP.
It should be ready before christmas time:)

[azian6er]

ok cool spoolin, let me know when you get it done.

[spoolinmp3]

Not a problem:)

So, a customized GReddy e-manage package? Or a totally seperate unit? Can't wait to see what you develop. :)

You guys have to remember that the ECU in the JDM FS engines uses a different PCM than us. Ours is manufactured by Ford for the US market. If you take it out, it says Ford all over it.

[DooMer_MP3]

As far as I know, the eManage works on our engine for fuel, but NOT timing. So it isn't a complete solution. Unless Terry has found a way around this.

Hey anything is possible, if they can get the e-manage to control both factors, I'd be all over this thing.

[AFaceInTheCrowd]

man if the emange could control timing, i'm all gettin it. hopefully spool will be able to get it to control the timing.

[MP3skaterNC]

ive got it as a fuel computer sitting in my floor board right now. not hooked up, just there, lol. it will be wired up tomorrow though.

[paladin]

e- manage doesn't work for our cars right now, it needs a code to work with our computer, the code for the FS-ZE engine won't work, just keeps sending error codes.

[spoolinmp3]

Yeah it wont work with the FS code it has to be internally set for our our FS motor.
So, a customized GReddy e-manage package? Or a totally seperate unit? Can't wait to see what you develop. Yeah it will be a full package with emanage, harness's, sensors and our maps
As far as I know, the eManage works on our engine for fuel, but NOT timing. So it isn't a complete solution. Unless Terry has found a way around this. Yeah it only does fuel:(

[AFaceInTheCrowd]

so terry, no way on the timing?

It looks like the e-manage does timing too... :confused:

Also, will we be able to use the boost limiter cut (http://www.mohdparts.com/emanage/manuals/emanage_software_manual/021.JPG) setting?

[spoolinmp3]

Yes boost limiter cut can be used along with anti-stall
However the emanage timing provision will not work with our ecu

[orangezoom]

My guy is doing it for me right now as a matter of fact Greddy wanted him to give them the diagram when he gets done.

[orangezoom]

he has been working on it for two weeks now just waiting for my exhaust then we go to the dyno with the laptop.

[spoolinmp3]

Sweet, is it on your car now? Are you using the pressure sensor?

[StuttersC]

Interesting....I remember about a year ago no one could even get the thing to work.

And now we have people trying it for real once they figured out what was going on with the thing. Cool...

It'll be neat to see how it works out.

[mazdamp3_18]

my plan is to get the emanage but im not going to boost my car ... im keeping it n/a...

since i autox alot ... boost really wont be that great... n/a has more linear power.... and i can slowly build up...... and im mainly going to concentrate on suspension tuning....

[chooch]

I don't know who said that the the emange doesn't control the timing. I've been using it for almost a year now with the ignition harness installed and I know the emanage can manipulate the timing. I tuned to induce a little bit of ping to confirm.

[mp3moose]

Hey Terry,
Need a car for beta testing?

[Guru]

I can also confirm that the E-Manage works perfectly and does control timing. You have to use newest software and make sure you wire it in properly is all.

[azian6er]

what type of car are you running it on, Guru?

Also are you in Novi, MI?


--B

[Guru]

I've run it on MP3 and Mazdaspeed. No issues. Yes I am in Novi, MI

[jersey_emt]

People are having problems with the E-manage (and any other piggyback for that matter)...the Ford ECU in the Proteges, over time, 'learn around' the piggyback, eventually bringing all of the fuel control/timing/etc. back to stock despite the piggyback altering the sensor signals.

You have to constantly adjust the settings to overcome this, and eventually, you will reach the ECU's limit...and it will simply give throw a CEL.

Stupid question... but can we use a JDM ECU on our cars? I know it probably won't pass smog, but will there be other problems (gauges, sensors?) How about check engine lights and error codes?

[Guru]

ECU will compensate part throttle to make it stoich but full throttle maps will only be affected if there are long term fuel trims due to miscalibration of part throttle mapping. THe goal is to make part throttle long term correction 0 or close to it so that it wil not correct and not apply those corrections to the full throttle maps. You have to understand how the stock ECU works before you start tuning it, otherwise you're wasting your time.
As for JDM ECU, if it works on USDM cars it will function normally but timing may be a bit aggressive for our fuel and also it will lack any of the OBD II extra sensor codes (so you could remove those sensors and not trip any codes).

I'm pretty confused. Several experienced tuners are saying the same thing...the US Protege ECU does not work with piggybacks. You're saying that it does work, as long as it is used properly.

From what you posted above...are you saying WOT corrections will only work if you leave partial throttle maps alone?

Also, about the JDM ECU....if I'm not mistaken, the Japanese 2.0L Familia engine makes 170bhp instead of the 130bhp 2.0L Protege engine here. Is this simply because of the different ECU's, or are there other things involved?

[mazdamp3_18]

the fsze (jspec fsde) is not just the ecu...
it has higher compression , larger cams, a better intake manifold and stiffer valve springs for a higher redline...


i think what guru is saying is that when you change the part throttle maps such as -5% .... the ecu will notice the change and compensate by adding 5% fuel to all the maps ... open and closed loop...

if you just change full throttle maps then the computer will not change the settings because the computer will only conpensate for the closed loop maps...

here is my question ... if i change my cams on my car the ecu will compensate for the added air coming in...

so the ecu will still add the fuel to closed loop operation...
in open loop it will still use the factory set parameters...

so i can then use my emanage to modify the fuel maps in full throttle to lean the car out more....

am i correct about that?

The FS-ZE makes 170 ps. Not bhp. It's a different measurement. I'm still trying to figure out how the hell everyone confuses ps for bhp.

It converts to somewhere around the 160 bhp range, give a few ponies I think. The exact conversion is in the Protege FAQ. And I don't feel like doing it right now.

[Guru]

Well remember it depends on the correction that the stock ECU is running at part throttle. SOmetimes you have to alter the map to get those correction factors back to zero (such as with bigger injectors). SO for example, you have a 380cc injector and the ECU is pulling maximum of 25-30% of fueling to try to maintain stoich mixture. To get the wide open maps to work correctly you have to first take out enough fuel so that the ECU is compensating very little at part throttle and idle (I try for less than 5% long term). SO this may mean your part throttle maps are at 20-30% reduced MAF voltage but this willl keep ECU withing spec of what it wants to do and thus will keep your open loop maps from moving around on you. If you adjust very little and you have a correction factor that is moving around on you then so will your open loop map and thus cause issues. Tuning is a tricky thing and I think it has to be done in a certain way to get best long term results.

[mazdamp3_18]

dan .... do you think i could come by your shop and you could check out what im doing wrong with my emanage...

also what would you charge to help me tune my emanage on your dyno?

i live about 30 min from your shop.

thanks
chris

[speedfrk]

good luck on getting it to work . the ford pcms have issues with holding a tune because they will fight against what you tune into it after time .

[Guru]

I'll get it to work for you Chris. It's all in the tuning and that's what I do everyday. Yes swing on by if you like. We usually charge $130 to install an E-Manage. We'll load in the newest software for you and we'll check unit and car for any codes and what not. I'm pretty booked this week but next week is okay. Just give me a call if you need to schedule anything. We can dyno tune it afterwards as well.

[mazdamp3_18]

well guru i have the emanage installed with the ver. 1.10 software ....


what are the rates for tuning?

how will you get around the fact my car learns that there are changes made and then compensating for that...

i can only tune in open loop...

which is about 4k-redline....

Just subscribing so I can see the answer to this.

[Guru]

Open loop mode tuning is affected by what is happening in closed loop so you can not tune one and not the other. You have to zero out to correction factors part throttle in closed loop so that no correction factors cary over to the open loop modes. If you do that you will have no issues. If you do not whatever correction you see in part throttle will carry over and affect your open loop tuning. Bottom line? Agood tuner can do it no problem but you need an advanced OBD II logger, a wideband and a dyno to do it properly. Please give me a clall for rates Chris as I don't want to violate the rules of this board. My website is below. Just click on www button.
