i baught a jdm turbo 2 swapp and when i recieved it the complete harness i was suposed to get was hacked off in several spots. well i just installed my motor and trans like normal and then i modified the na harness to run the engine. runs pretty flawless with the na ecu, but when you plug the turbo 2 ecu in it falls on its face around 3krpm. ive stared at the faq forums and havnt seen a write up on modifing a na harness for a turbo 2 swap. has anyone ever done this or might know how to do it. thanks for any help

 

N374 is the ecu you don't want to use unless you get it chipped. But if you want the car to run good, just run a N370 ecu. It's the us spec ecu.

 

is either if the ecus you listed a turbo ecu. what did they come in

 

do you have the turbo pressure sensor and air flow meter? otherwise when you hit boost the ECU isn't going to know what to do.
