That's not a bad idea either!

So in a nut shell. He piggy backed all the inputs he needed from the curent ECM to the 7427 and then ran the wiring from there out to the transmission. Then he flashed the 7427 to what ever vehicle...

Good Morning Gents, its been awhile. I was just wondering if anyone knows of a thread dedicated to just using and ECM as a stand alone transmission controller.
