I just sold my Apexi Power FC and now i need to put back my Stock ECU. The 4 wires that you cut out when installing the PFC, can i just leave it cut and put back the stock ECU? I dont think i can but if not how do i put back the stock ECU?

 

Aren't you able to splice the cut wires back together? If you can splice them back together, you should be able to plug in the original ecu and be good to go.

Nathan, I read your other threads about the engine rebuild costs and such. It sounds like you really need the PFC money I paid you for a genuine cause as you are having difficulty with your car. If you can ship it out soon, you don't need to give me a refund. Just please stay in contact so I know what is going on.

Believe me, I know how frustrating it can be when it seems like everything is going wrong with a car...BTDT. So I apologize that I was annoyed when the PFC didn't get shipped when you originally said it would. Anyone will get freaked if they suspect they have been screwed. Just please contact me so I know what is going on.

Techjnically you should reconnect them, but they are only for emissions related stuff:

4F - Split Air Bypass Solenoid Valve Output
4O - EGR Solenoid Valve Output
4P - AWS Solenoid Valve Output
3J - EGR Switch Input / DRL Input (Canada)

I think you'll probably get a check engine light but I doubt it'll affect driveability.

 

Chris, I appreciate you being patient with me. Feel free to give me a call anytime so we can discuss what you wanna do. I dont get great reception with my cell but if you leave a message i can get back to you sooner. Happy New Year.
