Peak and Hold ECM rewire?

Hey guys,

I installed peak and hold injector drivers in my ECM about 4 years ago and rewired the harness to run both drivers but I started having problems a week ago at WOT.

I wanted to double check all the pins in the ECU harness because I recently replaced some of them that were loose but I can't find a page Ron Gregory had up for a long time about the rewire. I belive it was using C10 and C11 as outputs and tying C13 and C15 together and D5 and D6 together....I'm not 100% though.

What are some other part #'s for other drivers. I can't remember which ones I have. I'm pretty sure I have a driver that's failing but I wanted to double check my wiring at the ECU first.

I've searched the board and I noticed some people are installing the peak and hold drivers without rewiring the ECM.....I tried that at first but under WOT it would lean out for no reason, so I rewired it and have not had a problem since.

Ya that is weird we do not do the rewire on the ECM's at all and have not had any problems. And there are quite a few trucks runing this way with no problems. It might be a driver crapped out on your ECM. Make sure you let me know what the scope shows.

I ordered 10 of the 44 amp Fairchild mosfets today. I'll have them Wednesday. I'm pretty sure that's the problem.
