PFC Issue
 

Hey guys
Got an issue with my PFC and hoping yall can help me out. Recently got a PFC with Commander off the forum and install today. Cut the 4 wires at the engine harness. Went to start the FD. it will start but within a seconds the car dies. Try second the second time keep rev up to prevent it from dying but the moment i let go of the gas pedal it dies. reset the pfc setting and fire it up the third time still no luck same issue. and when after the car die there is a buzzing sound coming from around the throttle area. so i refitted my old ecu and the vehicle will start right up no problem. Any idea what could be the problem.

Info
93 FD with catback exhaust, ast, and some suspension work.

thanks

did you follow all the instructions and howto-s including the part where you tighted the bypass screw, then back it off?

Did you reset as well so it does the idle learn function? There is a manual out there that helped me when installing it.

Did you cut the correct 4 wires?

Guess its easy to just post the link, as everything asked so far is in it.

The main question is about the used PFC you purchased:
Is it's map sensor and injectors setup the for the same hardware as your car?

If your FD engine is stock or close to it, you might need to initialize the PFC.

Have you read and studied the PFC manual?

This thread is going to be useful to me too. I purchased a used newer serial number OLED PFC so it won't come with a manual. I did read Dale Clarks manual to the PFC.

OK thanks guy i figure it out what happened. i turn the idle screw too far back so readjusted and everything is fine now.
