OK- here is the info on the FP reducer kit....

[kwiktsi]

Ok guys, I have parts coming for 20 kits on Tuesday. The check valve is a different one than I have been using, it is a much higher quality. But as with all changes, I want to do it to my car first. If it works the same (as it should), I am giving this an all clear.. You can start to order whenever you want (the sooner, the better to cover my expenses).. The price will be $25 including shipping. For $25 you will get-
1) 3/16" ball and spring check valve
1) 3/16" hose tee
3' of 3/16 hose
1) 3/16 90 degree elbow
1) rubber grommet
1) 5/16" drill bit
1) instruction manual
all shipped to your door...

Without going too much into detail- the checkvalve tees into the FPR line to reduce the amount of boost going to the FPR. It then has a return line from the check valve that goes to the air intake hose (hence the drill bit, elbow and grommet).

Before people start saying "bleed the boost going to the FPR- WTF?"- this car runs ABSURDLY rich up top, I have never seen a stock car dump so much fuel in my life!!! I have bled off a hell of a lot more than this and was still richer than I would like!!! This kit in the couple test cars has lowered fuel pressure enough to make the car run more consistent on hot days without falling on it's face- yet remain very safely rich..

While I am more than confident based on over 1000 miles of testing that the kit is safe for all conditions, I would prefer the first few orders come from people with AF gauges just so they can monitor it for me.. If I hear of anyone runnig too lean, I will let you all know of the problem. I seriously doubt that will be an issue however- my car has been in FL on mid-90 degree days and up here in NY where it has been upper 40's at night with no adverse effects at all- I am just trying to play it safe :)..

I hope you guys find the price fair enough for what you get, it is about $17 worth of stuff including the drill bit and I am doing your shopping, R&D and packing for you :).. If you feel you need to copy it to save yourself the $8 and do all the running around for yourself, have fun- you unoriginal, can't figure anything out for yourself bastard :D ..

I am now accepting orders- my paypal address is sales@joepmbc.com

If you have any questions, either reply here or shoot me an email at kwiktsi@nycap.rr.com

ONCE AGAIN- this is not a cure all for all the tuning issues or stumbles that this car has, but it GREATLY improves the 4500 switchover stumble under boost and keeps the car from falling on it's face up top.. It is recommended that you at least have a K&N filter for increased air flow though, but it is not 100% necessary.

Thanks.
Joe
PS- Once I get the supplies on Tuesday, give me a couple of days to get the instructions written up (I am starting tonight, but need the kit here for reference purposes for me to finish them).

[kwiktsi]

Just FYI in case anyone asks- the reason(s) this goes back to the intake hose are 1)so the vacuum created in the intake pipe will help draw some pressure away from the FPR- even more so with more intake restriction- less air needs less fuel- and 2) not that it is much, you will have a leak of air that is "counted" by the MAF coming out of the checkvalve- any air that is counted, the ECU supplies fuel for- if the air leaks out, the fuel is there- the air isn't. While this isn't much at all, this car is so rich as it is that it doesn't need any reason to be any richer, so the air gets recycled back through the intake..

Just to re-iterate- I cannot promise that everyone will get the same gains from this- this car is so poorly tuned that no two run the same and climate plays a big role in how it runs also. Whether you "feel" a seat of the pants gain or not, it will definately help pull some of that excess fuel from the thing :).

[ForceFed]

What are you asking us to drill? I'm not sure i'm following the drill bit idea!I follow everthing up to there.A little more detail please as i do not plan on putting holes in my intake or anything crazy like that! Whats up with this joe?

[kwiktsi]

The hole is going in the plastic intake pipe before the MAF. You *can* substitute for drilling a hole if you have a K&N and just want to poke a hole in the neck of that like you did for the Air Temp sensor, but I prefer going further back on the intake hose. It is a 5/16" hole, so it is nothing too drastic. If you ever wanted to remove the kit, it would be easy to plug.
Joe

[kwiktsi]

yeah, I just re-read my post- it does look kind of like I am referring to the intake manifold :).
Joe

[ForceFed]

ok ok wait ,I gr=et what you are saying now but if you go before the MAF you are re-introducing air that was in the motor already before the MAF so it can re-read that small amount of air?Wouldn't it make sense to put the air back into the motor after the MAF to lean out the mixture even more without having to bleed off as much?
Matt?

[laptopheaven]

I am guessing that it is such little amount of air it would not matter. The reasoning for before the MAF is just in case something goes wrong, it reads the air, so the motor wouldn't go lean.

[kwiktsi]

Exactly, that is why I prefer to go before the MAF- well I guess it is after if you are going in the direction of the airflow- I am thinking before it in the engine bay coming from the FPR- my bad :).. The K&N thing is a last resort.
Joe

[ForceFed]

ok ok i got you ,you mean after the MAF but before the intake into the motor !Now that makes sense!That was where i got confused because it didnt make sense the way you typed it but now it does .It's just like i was thinking it shoud be!

[kwiktsi]

It is such a little amount that it wouldn't really matter, but any little bit will help since this car runs so rich :).. The main reason for the hookup to the intake pipe is to use the vacuum that is in that pipe at WOT to help pull more away from the FPR- a clogged or restrictive filter will create more vacuum giving it less fuel- less airflow needs less fuel :).. Trust me, it works :).. This car just goes open loop and dumps fuel up top regardless of air flow or temperature, which it why it helps to mechanically manipulate the fuel pressure for boost/airflow.

Also, read my last reply- I really mean after the MAF if you follow the air flow :)..

Sorry for the misunderstanding- it has been a long day, not thinking too clearly :).
Joe

[ForceFed]

It's all good ,it's sunday and it's late so we will work with ya!:D
So we will still run uber rich at anything above 4500 because the com goes into open loop right?It is only possible to manipulate the fuel curve below this rpm or will the blled off help throughout the rpm band?

[kwiktsi]

You will still run safely rich above 4500, not uber rich anymore :).. The problem was that at 4500 the car dumps so much fuel that it would fall on it's face under boost. This takes care of that by dropping the fuel pressure a bit while the car is under boost.

Below 4500 will have to be addressed electronically- that is next :).

The pressure will be manipulated any time the car is under boost however. Vacuum and normal cruise will remain the same (for now- hehehe)
Joe

[trekv2]

hey you came back! GJ. on the low ballin tuning. i willkeep this in mind when all this gets worked out.

[kwiktsi]

Just curious- what do you mean by worked out? I'm lost :).. this kit is "worked out", there are other products in the works to address other issues (in case there was a mis-understanding :) )..

I am going to stick around for now- I got a TON of email asking me to please stay and help out around here and telling me to ignore the a$$holes :)... I'm trying :)..
Joe

[kwiktsi]

damn, I gotta lay off the smilies!!!!
Joe

[RuggedMazda]

From what have experienced, my stumble comes in at around 3000RPM’s & fades out at 4000RPM’s. After 4500 I feel the power just fine.
I’ll still be buying the kit to see what effect it has, if not just to work on my car for the fun of it.
So what do you say about that kwiktsi? Does that sound right?
Maybe I’m not getting it or maybe I’m not running that
Rich above 4000RPM’s for some reason?????

[PaulMP3]

Good work joe, you provide the best bang for the buck mod. Keep up the R&D!

That is probably because of how cool it's been lately- rich cars like cool weather.. Wait for a hot day and you will notice it :).. Mine would surge off and on throughout the RPM range and just feel like a Hyundai above 4500 on hot days.. This smoothed a lot of it out down low and really improved the 4500 switchover- it pulls right to redline now with no problems.. The low RPM stuff is still there, just not as bad.. Driving the car from NY to FL was the best thing I could have done to get a feel for how it runs and when it does what it does... I would REALLY notice it if I were driving down the highway and I rolled on the throttle in fourth and let the car slowly accelerate without going WOT, it would pull nicely under boost than when it would hit 4500, it would feel like someone flipped a choke closed on it!!!

Where in NY are you? If you aren't too far, we can meet up and compare notes and such.. I'll let you take mine for a spin to do a back to back comparison. Let me know.

Thanks!!! Normally, I would just go for an AFC or something to fine tune with, but mechanically is really the only way to address this with the ECU as-is... It does make for cheap modding though :)..
Joe

[servoeyes]

Damn...while I'm not sure I want to go drilling up in my stuff, this kit is showing a TON of promise for 25$! You da man Joe...(bowdown)

I am humbled. It's a great and simple design, that not just any shlub whould think of. Good, sound, and solid engineering at work here...I love to see that! I may just pick this up after full beta of v0.2 is complete. Damn Mazda for draggin their feet! But thank you for hanging around and keeping us all on your mind! Good job!

[kwiktsi]

If you have a K&N, you can tap into the filter neck instead, but you will get better results in the pipe..
Joe

[chwood]

Joe = da man

<bowing>

[tekkie]

Joe just sent ya some PayPal :) can't wait to get it installed, if anyone else in the GTA is ordering one maybe we can have them shipped together to save some border fee's. Oh thats a good question, what about the shipping to Canada Joe? was that included in the $25? if not let me know and we can work on it

[kwiktsi]

Don't worry about extra shipping there, it is light.. I just hate those damn customs forms, but I think it may be light enough that I won't need them.. It is only over a certain weight. So you probably won't even have fees on your end..
Joe

[tekkie]

good point Joe your probably right

[RuggedMazda]

Where in NY are you? If you aren't too far, we can meet up and compare notes and such.. I'll let you take mine for a spin to do a back to back comparison. Let me know.

I'm in Wingdale or Dover plains, We should me up some day.
I would love to see your car & compare it to my car.
lets set something up next month ( to many bills this month
to take the little trip up to you )....

[Go Mifune]

Maybe those who don't want to drill their stuff can order a new pipe and keep one with no hole and one with.

Thanks for the work Joe!

I don't want to leave my Stock class in AutoX just yet so I am not modding anything. This little mod here though really gives me some incentive though. I really hate when it falls on its face like that.

[kwiktsi]

That pipe probably isn't cheap from Mazda. I would be curious to find out though..

As for "stock", do you think anyone would even notice an extra vacuum line? Maybe I will look to find an "OE" style hose so it isn't as noticeable :).. The hose I am using now is fuel/vacuum hose. Maybe I can find something with a thinner wall..
Joe

[MazdaDryvr]

yes, the car runs rich. That would explain the way it feels at certain points along the rpm band. This work you have done sounds like it will help out. Are the instructions, ummm, layman friendly. ;) diagrams and such? I would hate to drill the wrong hose. :)

This kit will help with the over rich condition while under boost. normal cruising will not be affected.

The instructions will be fairly straightforward. I was going to have diagrams, but my drawing skills are non-existant :)..

The only pipe you drill is the large plastic pipe that the MAF and airfilter are attached to.

what will the results be with the upcoming injen intake installed? i dont have an accurate A/F or any A/F at all actually , or a wideband or any of that stuff, so....would it still be very safe to drive?

if you already mentioned the Injen, then sorry, i didnt catch it :p

[kwiktsi]

Originally posted by I-Am-Chris

Then you will run pretty much as strong as I did when I pulled (slightly) on the 01 Mustang GT :)..

It has been tested on more modded cars than stock.. It is the stock ones I am anxious to get feedback on :).
Joe

[MazdaDryvr]

well my car is stock except for a drop in K&N. I have felt the "stumbling" and wondered why it was there. I sure would like to see it gone. If it could run smooth......sweeeeet!

You will be fine. I wanted to get the kit to people who had proper gauges to monitor things first just in case the various climates give mixed results, but based on the three test cars (scattered acrross the country to test the climate thing), there will be no problem for anyone.. I'm sure if there is a weather change and something doesn't seem right, people with AF gauges (including myself) will sound an alert. I am very confident there will be no issues though as it is still pretty rich up top and has more room to be leaned out for optimum performance- I just wanted to keep it safe also.
Joe

[boostisgood]

Joe,

If the kit is ready to ship. lemme know, I'l PayPal ya first thing.

Thanks,
Craig

[kwiktsi]

They will be ready by the end of the week. I am accepting payments now (it'll help recuope the $$$ I put out on the order :) ). I have 20 coming, first come first serve :).. I have like 6 or 7 orders so far.
Joe

[Vapor]

This is probably a very stupid question, but can all these rich fuel problems be solved with the upcomming stand alone ECU management system?

Vapor

[kwiktsi]

If you get a stand alone that will work with our car- yes. If you wan tto go through the install, expense and tuning :).. I am constantly looking for something that will work so I can use it on my car and the only things I have found were piggyback systems. A true standalone is near impossible to install correctly as our ECU sends the signal to the speedometer, tach, temp gauge, etc. and controls the voltage regulator in the alternator.. It would make for a very challenging install :). Stand alone systems are not for beginners by any means.. A piggy back can be tuned at a shop and driven by anyone- a standalone is a totally different ballgame to get right and is not for everyone.

Joe,

How ya doing? I'm a fellow DSM'er so I'm experienced with your work throughout the years.. keep it up big guy!

My question to you is: If this mod is done on a MSP and the owner decides to get a full 3" exhaust with no cats, better intake, etc all to improve hp (which will also make the car run a little leaner), and he decides to raise the boost, could the car run too lean with this mod? Would you recommend not doing this mod for this situation?

very well put joe.
the module me and joe are working to get together will be a piggyback that interfaces with the stock ecu to control the boost cut, fuel injection and ignition characteristics.

nope much more effective.
greddy e manage cant control timing. they tried and that particular cable doesnt work. we can control both fuel and ignition along with another driver. either boost or boost cut etc

You pretty much described my car :). This mod will still leave the car rich enough to be safe for any application. The fuel pressure regulator is a rising rate, so it will still increase fuel pressure as boost increases- just not at the same ratio. People who are serious tuners will be able to take this setup and still figure out a way to pull even more fuel for the most performance. I have to leave it well on the "safe" side since it is going in everyone else's car too under all sorts of conditions.

whats this piggyback module gonna run me? I think we all need it bad, thanks a lot for making it.

[boostisgood]

Joe,

I paypaled the 25 bones to ya :D any ETA on shipping for this item ?

you can PM me or hit me up at sportuningguru@yahoo.com

Thanks,

P.S. Lemme know where you are getting your 3 inch piping done, no shops around here will touch my dam car for exhaust. :mad:
