can someone tell me which wire need to be cut on the power fc, and why do you have to cut them?


thanks

 

You should have gotten instructions with the PFC that shows you which ones to cut. If you don't cut them, the ecu will switch back and forth between two idle settings hunting for the correct one causing the rpms to bounce when the engine is warm. Annoying, but it won't hurt anything. If you can't find the instructions let me know and I'll dig mine out for you.

 

Yes, PLEASE dig them out. I need to check mine as well. Then again....if you simply disconnect the AWS, then it won't hunt for idle

Thanks skotx, you beat me to it.

 

thanks for the help guys!

 

I think I might just end up removing the pins from the PFC. There is a vendor, which I have heard, that completly removes the pins from the PFC. Afterall, if the PFC doesnt need those wires, then it probably never will.........right?

 

Flybye, XS is the one who removes them for you. There's one problem. Open up the ecu and look at the boards. You can't reach the second row of pins. You need to pull/cut them from the outside which isn't the easiest thing to do. I tried, but it turned out the little nubs that were left were still making a connection, so I ended up going back and cutting the wires.

 

I believe SR Motorsports cuts/pulls the pins as well.


FYI...

16-pin connector

3J blue-green EGR SW (Calif)

26-pin connector

4F black-red SPLIT AIR BYPASS SOL VALVE
4O blue-yellow EGR SOL VALVE
4P brown-yellow AWS SOL VALVE

 

Remove the wires from the factory harness. It's a pain in the ***, but worth it in the long run.
