so a friend of mine that just got an eg hatch that has a d15b1 block with a z6 head. and it is running a obd2 p2p vtec ecu? do you think the obd2 ecu that is making the car run on limp mode? that is what i was thinking. thanks and yes i did search and didnt find anything

 

nobody? and it rev limits at 5500rpm

 

Why is he using a P2P ECU? That ECU will look for a secondary O2 and the CKF sensor that his car and engine won't have. He needs to run a P28 OBD1 ECU made for the Z6 engine.

 

we just got the car like that.
