I have an ECU without the immobilizer chip, and my doesnt start......Do I need to take out the immobilizer unit under the dash for the car to start....? Please help me, the shops that I asked said, that I need to put the immoblizer chip back in, but I think they are trying to get some extra cash from me.....Let me know pleas!!!!

 

Post some more info if possible. What year is the car (I assume it's an R since you posted here). Also what ECU (P28?) and what type of jumper harness are you using. If you install a non immobilizer ecu w/ harness in a 00-01 R, the system is no longer active-meaning it will no longer prevent starting of the car. You may have an issue with a faulty ecu or incorrect harness.

 

It's a 2000 ITR (p73)Ecu, in a 99 GsR. I posted this thread here because the ecu is what I think is has the problem or it might be the immobilizer unit, its the stock harness that goes straight to the ecu. PLease let me know. Thnks

 

Yes, the ECU would have to be reprogrammed at a dealership in order to work in another vehicle due to the immobilizer system.
