OK Pat, it has been a while since your last post here. How is the car running with the MAP? Is it 100% better, is it fixed, or are you still having problems?

How about an update on your car on this thread?
Car still runs like s***. I believe it has more to do with the O2 sensor being on over 120,000 miles. The clamp is clamping and doing what it is supposed to do. For some reason, I I still lean out. I may be running in limp mode. One CEL keeps occuring daily. P0171 Bank One Too Lean.

odd. last i heard from him and pat he was dropping it favor of his own AEM
Shows how much you know, ask people, or read about. Don't automatically assume things.

Beau is developing the AEM as a full stand alone system to complement the piggyback he offers. Not alot of people are ready to dish out more than 2700+ $$ for the AEM.

I actually have not really seen alot of these positive messages in comparision to the numerous negative ones, so if there are a plethora of praises I'd be happy to read them. Unless you mean the positive ones from the people whom you have tuned yourself. I am not here to "cause s***" as you put it because I really have nothing to gain from that. I post because of the impressions I had from what I had seen and heard from people who have owned and been tuning this car for a long time, as well as what seems to be the same damn problem over and over and over again on different cars. plus you seem to take a pissed off and hostile approach to anyone who even suggests that the MPI is not the Lord's gift to engine management. and excuse me for not exactly digging the software.
Well it's just typical human nature, for people NOT to post when they do figure out the problem they have been having. Too Embarassing!!!

Also people tend to post when they need help, and not so much when they don't. You can go back and READ this thread all over and you will see that all this has been covered.

You say you don't stir s*** up, but that's exactly what you did with your useless comments. Progress had been made as Nick was trying to settle differences and was actually trying to help. ( Even people he disagrees with ) So go back and read the thread and until you finish. STFU


already have one and its ran solid from day one, has been a relative breeze to tune.
I am happy to hear that. I have allways said that any EMS system will be able to tune our car. Provided the CAR runs well in the first place. I'm sure if you had a defective IAT or 02 sensor or even if you installed your MAF backwards, it wouldn't be running so good. Right ???
 
yeah, I can attest the only problem Beau has personally ever had with the MPI is the fact he can't keep on ein his car. He has to keep uninstalling his to give to other people.

the AEM as mentioned is for the truely hardcore or just plain rich, though it wont cost around $2700, unless you start adding parts you would want to have with any other engine management like a WBO2, or a CDI box. but you dont need these. look for pricing around $2000-$2300 or so... but it will all be seen in the final pricing. it isn't done right now, because there is only 1 sensor left to calibrate/make work, but everyone at AEM is on Christmas break. but soon, it will be all done.

also, Beau has not dropped the MPI tuner, the most you could say is that in light of some threads like this one, some people dont want it, or already have a RRFPR, etc. or just want to save money, so Beau is listing his prices without any management. He still sells the MPI and will sell it to anyone who wants it with their kit.

but here is the real reason of this post: its a new year guys, chill out on this topic. there is a lot of misinformation, and a lot of biased opinions on both sides. accusations, and name calling (not just in this thread, the whole debate) there are much better things to spend your time on.

see, if you dont like the mpi, or you like "X" EMS better, great, if someone asks a question in a thread, tell them what you think, but dont say, hey, the MPI sucks. either let them decide that for themselves by purchasing it, or reading about it. If they decide they want a different EMS or just a clamp and a FPR, then so be it, you aren't going to change their minds. but either way people want to go its not worth it to tell them some part sucks because you read it does. if so many people didn't jump into threads and do this then Nick wouldn't have to spend 99% of his time on this forum just defending a product that DOES work, even if it is a little tricky at times.

enhance your calm, and enjoy the new year

Far from an assumption. These were things I heard from the horse's mouth not too long ago. If thats changed or thats simply not the way it is then I'm sorry, but I went by what I heard.

I don't know if I agree that any EMS is suitable for the car. I guess I have trouble with the thought that coinidentally all of these people had problems with thier cars, didn't seem to post about those problems until the MPI was installed. Or like Dana who didn't have a problem, couldn't get the MPI to what he wanted and went his own way? Call me a skeptic.

I am interested in the MPI, really. I'm not here to start a flame I'm just tired of seeing "problems with mpi" thread. I do have a technical question about MAF tuning. Most of the turbo systems for the protege do not 'blow through' the MAF (the MAF is pre turbo). How does the MPI tune for airflow from the MAF if the turbo is not forcing air through it?
 
because wheither it blows through the MAF or, "pulls" it through its still the same amount of air. (not counting air that is blow off, via the BOV)

Well personally I am responsible for installing and tuning 4 MPI's here in Canada. They all run well and haven't been back once claiming the MPI is not working.

Dana is not and has never run the TM. He tried to run the maf for maybe a week if that. He only asked a few times for help with setting it up. Danas style is to do things on his own. Thats cool because he has learned many things this way. The only problem I have with it is he that started to MAP BS. It has not proved to help anyone. Dana could not get the MAF to work and then call out to everyone that it cannot be done. Some of you guys seem to thing that he knows what he is talking about. Good for you, time will tell how much he knows.

Ask youself a questions. On one side you have the people who tune right with the MAF and have no problems can come here and say it works. Why are they wrong to say so? One the other side one guy comes here[Dana], who is not a tuner or understands as much about cars as he thinks he does, but he is still learning as he goes. Who could not get the system to work as it should have been tuned. Who cannot understand that he did not help these people fix their car, their problems are still there. So why is he right then? What has he proved? What has he fixed? What has he done that was right with his way?
 
well since the thread has gone south, i got an mpi and i love it. yeah i had problems but it was something with the installation. guess people that like the mpi dont have a need to make a thread about how much we/they love it. nick has always answered my question and has great customer service imo. i am far from beign a beginner tuner. i barely have time to mess with the software, but from what i noticed is that if you use a serial connection the software will not crash or anything. rambling...
 
I agree that a serial connection is best. Hopefully I will have a couple of new (read: used) o2 sensors soon.

This one did get by me. I did not tune with a USB from the start. Every now and then I would get a datalog e-mailed to me and I could not get it to run. Never knew why until a customer with the MPI found it out. Now I always tune with a USB. I found an adaptor that work 100% fine all of the time. I can get them if anyone needs one.

I know this is going to come across a little rude or harsh, but why haven't you replaced your o2 sensor yet? The factory ecu is still primarily running the show. Maybe you don't understand how much that affects your car, but it's practically pointless to try to tune around a bad o2. And o2 sensors are so simple to replace. And they aren't that expensive. Just do it, and then re-address your other issues if you still have them afterwards. I would assume that there may still be issues afterwards, but at least you can start to adequately diagnose your problem.

You cannot fix a problem by just wishing it away. It doesn't matter which method you prefer to tune your MPI tuner, it's more important that your car is running properly, and I know part of my point is just a re-iteration of what other people have already pointed out.

fix your O2

I had my O2 re-wired wrong after wires and plug melted with wastegate. And had all this problems. Car was leaning out, even with extra injectors.

But now, my sensor tends to read only stoich, something is wrong with it, but it still sends some voltage variations that the MPI reads between lean and 13:1. So the clamp is still working and no pulling of fuel.
 
I am definitely running in limp mode. The timing advance is all retarded when I am driving around, and this is before I even hit boost, and before the MPI does anything! Then when I hit boost, the less than normal timing retard, coupled with the retard action of the MPI is too much to handle. Horse Power is GONE! I was monitoring the pre-MPI/pre-boost affected timing advance with my PDA Dyno software, and it was less than normal for sure. O2 sensors ordered today.
