ive read somewere and tryd searching but no real answers why the usdm harness dosent work right with the j spec n374 any thoughts as why is ther something that needs to be done ? i know i can chip it and that will solve the problem but what holds this ecu back ???

 

I've read that 9 times out of 10 your rear primary injector will not fire with the N374.

 

i used 3 n374 ecu's wont fire rear rotor injectors, save our self time and money and just get the n370

 

The story is that the N374 will usually not work with a swapped car but usually will work with an original Turbo.

Some success is had with N374's that were chipped in Japan, Knightsports, etc.

Pocketlogger will chip the N374, but I don't think anyone has posted up that the chipped unit will work for sure on the NA swap.

 

just the answer i was looking for thanks guys.. ill just trade my 2 extra ecus n326 and n374 for a n370
