We had problems identifying which electrical connector went where. (IACV,IAT,PSPS).
At the moment no check engine lights.
There is vacuum at the map sensor port.

Will Having those three plugs mixed up fry a cricuit in the ECU?
Any body have any ideas?

Any help greatly appreciated!

 

Simplest thing to do would be to wait until he gets the OBD1 ECU. Then, plug into the datalog port and connect. Start car and watch the sensors. Unplug one at a time and see which one goes dead on the DL screen. Make sure that plug is plugged into the sensor that went dead on your DL screen.

QUIT running the car until you get it fixed!!!!!! You will end up washing down the cylinder walls before it's all said and done. Ross will not be happy at that point.....

I know it's driving you guys nuts but you have to be patient. If you want to figure out if everything is OK right now, get a US ECU and just plug it in. DO NOT start the car, just turn the key on. Connect to the ECU via the ALDL port and go to datastream. Once again, unplug the sensors, one at a time, and verify they are in their correct location. Once you know everything is right (if you actually had to change something) plug the original ECU back in and restart.

The reason I am saying you need to swap ECU's is because the ECU that is in the car right now will NOT communicate with a US scan tool. At least it would not communicate with mine.

If you guys need any more help, just give me a call or shoot me a PM on here. Trust me, I know it sucks right now but be patient until you get the little issues lined out. It will be plenty fun when it gets together.

 

lol, that was quick!

 

If you guys do not have an ECU, I think Justin is coming down tomorrow or Friday to dyno his car. I could give him a P2P ECU to plug into the car so you could do some checks with the scan tool. YOu will definitely have a code for VTEC pressure switch and also CKF sensor as the engine did not come with those... Should let you check all of the important stuff, though.

If you need me to send an ECU back with Justin, just shoot me a PM.

 

compression just tested, 165, 165, 175, 195


Ross wants you to call him when you get a chance!

 

DAMN. That is LOOOOOWWWWWW. Should be 220 MINIMUM. I'll give him a ring.
