ok i just got a N374 ecu for my GTU and im using the N/A harness because the guy (im not mensioning names) that sold it to me told me that i can use the N/A harness without not problem and no repining because he said that is the same. so i hooked it up and it missfires and no check engine light to pull codes and i dont know whats going on because i put the N351 ecu back in the car and every thing works fine and danding. so my question is what im doing wrong and if i can use the N/A harness and i have to repin it? thanks

anybody?

 

Turbo or non turbo boost/pressure sensor?

 

yeah as hailer said
did u switch boost/pressure sensors???

if your using the Turbo ECU with aNA N350 boost/pressure sensor, that will cause fuel cut on 1 rotor.

you need the N370 pressure sensor to make it run right.

( reason being the sensors have a different range, so when at low vacume on a na sensor the turbo ecu will think your running like 12 psi or more... )

 

well hit the ecu against the floor or break it on the guys head then go buy another one payit after u see is working fine

 

well im using the N350 pressure sensor. i ask before i strated this about it because i didnt have a turbo one and they said yes i can use it temporary i can find the treat about it. so i need a N370 sensor no matter what? can i use a N318 sensor or have to be a N370? what about the Knock sensor do i need it too to use it or i can install it later?
