I am running a p30 tuned for boost. I swapped in an obd1 dizzy and connected the harnesses. I have double checked all the connections to make sure they are correct and from what I see they are. I connect my ecu through ecucontrol. As soon as i connect and push start logging the MPH will jump to 116. The map reads good. I try to start the car and it will go to start and then die. If i hit the gas I can keep it running. I pulled out of the drive way and drove it down the road and went into limp mode. I may have missed a wire somewhere when going over the harness. But Im getting second opinions right now.
