Sorry dude, I forgot to post. I couldn't find it......it must have been in my car when I sold it. Give Nick a call or send an email to mp23cc@aol.com
MPI removal
Hi
I'm going to get my MSP registered in Norway soon, wish I didn't have to because this is going to be expensive.
My car needs to be stock when I register it. That means that the MPI tuner has to go, at least temporarily. I would think that the wiring harness and the O2 sensor can still be installed in my car, but the box itself has to go.
Only problem is that I didn't install it. Only thing I know about the installation is that it is placed under the floor mat on the passenger side.
I need help to rewire my car to stock ECU. Anyone here know what to do?
thanks

I had my car emissions inspected 3 times and a MD state inspection once and they never knew about it. There is no way you can know its in there unless they visually look at the ECU and see the wiring.
There was a spec racer that had one installed and the officials never knew. That guy had to take it off because he was beating the competiton and no one could figure it out so the next step was to completely go through the entire car to figure out why, so he removed it and lost his edge.....better then having the whole car disassembled.

It's a one hour physical inspection, and when they see the 2 lights by my steering-wheel they are going to check the ECU wiring for sure.
To put it this way; even my factory installed DaveB rings and 5% window tint might cause trouble at the inspection.
Basically I can follow the installation manual found in post 94 and re-attach the cut wires to the original ECU and then remove the MPI, right?

I would write down how yours is hooked up now and compare it to what is in that post. You may be O2 tuning which is different, if not, then those instructions will work. You will want the coils O2 and MAF back to stock, the rest is just tapped in.
That makes me glad I don't live where you do......that's a huge PITA to have to be 100% stock for an inspection.
i am looking into getting a turbo and engine management for the turbo...but anyways will my car pass an emissions test without me having to take the mpi out? also this will be my first time using any sort of engine management...how hard is it to do the programming?

i passed in MA no problem, no cats either! if you know your way around eng managment systems you'll probably be fine...
I passed emissions twiced in MD and once in AZ with it and no changes done to the MPI.
As long as you don't try to tune in closed loop, the ECU will not learn it. Once you get the settings right, tuning is pretty easy, find out where you need to add fuel and set the switch to kick the car into open loop and put bigger numbers in that area.
The MPI new from MPI is $585. Shoot him an email for more info, mp23cc@aol.com

A i just swap in a -30k motor i got from mazad3online and i can't seem to figure out why my car goes uber rich @ or around 7psi and misfires constantly at full spool 28~35k rpm (as well as randomly when idling but not as much) look at the plugs, ordered some coils though they haven't arrived yet and have no vacuum leaks just can't figure it out for the life of me and i was wondering if the MSP ecu i swapped in is the cause of the fuel cut/misfire the car has about 75k miles on it and everything is hooked and connected. Do i need to look at any of my setting on my mpi to see if the numbers in it are off? the last motor had a main bearing failure. should i get my old DX ecu and try that one? just wanted to see if any one has a clue or idea.

Check to make sure your analog out voltage is where it should be, 2-2.08v, then you may need to adjust the fuel where you are going rich. The rest of the map may need to be tweaked because of the different motor and fresh ECU settings.
If the analog out voltage is where it needs to be, then you must have some kind of leak somewehre, do a smoke test to be 100% sure. Every ECU reset will be a little different because of the OBDII, but you should only need minor tweaking.
Oh, is your battery strong? If not, you may want to change it out, if you don't have a consistant voltage to the unit, you will have problems just like with any other EMS. Good Luck

can you do a 2 step launch control with MPI?
This really depends on which turbo moduole u have but for the maf:
MAF Signal wire Sensor Side to the MPI Tuner wires blue #6, green/yellow #11, black/white #10 and the green Turbo Module wire
MAF Signal wire ECU Side to MPI Tuner wire violet #18
you should have 2 extra wires. one for the map (switch gray) and one for the extra injectors (gray/black).
