Hey i have a jdm s5 turbo ii engine my question is it has a n374 ecu will a n370maf and n370 map work on it ?

 

bump

 

yes but the ECU most likely wont work

 

*DONT TAKE THIS AS SOLID INFO*

I have both sensors (n370) with what I SUSPECT to be an n374, but cant verify. The engine is definitely s5 JDM TII, but the labels on the ECU are toast. To add to that, it has the REDOM mod, making me think that this is an n374.

Again, I'm not sure, but this is whats going on in my world.

 

If you check pin 3R with the harness all connected up to the engiine and elsewhere, then you could put the key to ON and backprobe the pin 3R at the computer and check your results with the results of a non turbo series five and a turbo series five (FUEL AND EMISSIONS.....CONTROL UNIT section).

The Turbo ECU would read under 2 vdc but the non turbo would read approx 12vdc on pin 3R.

Thats with a Turbo harness on the engine but I think if you had a non turbo harness on the engine and the solenoids connected up the readings above would tell you if you have a turbo or non turbo ECU.

I'm just guessing at this by looking at the FUEL AND EMISSIONS section of the FSM and comparing the non turbo results to turbo results.

 

the n374 has a lil tab with a black box on it thats an easy way to tell and hey midnfuaciusn hows that tps working out??

 

Well, its not working at all right now! I'm waiting for my ECU to come back from RTEK with the stage 2 upgrade!

Its been great. Thanks.

 

Just to let you know its a s4 tii car with a s5 jdm engine and harness I want to use my n374 ecu that came with the jdm engine cuz it has been chipped by r magic maybe that will make a difference I just need to know if they will work together as I have already sorted everything else out and it will all work a as everything has come from a turbo car and its going into a usdm s4 turbo ii any help would be greatly appreciated thank you all for your time and patience

 

you've got a big wiring headache in front of you. mixing s4 and s5 stuff is already a mess, then add a jdm harness and ecu into the mix? have fun. you are better off getting all s4 electronics, front cover, omp, etc.
