I just got my copy of Tuner Cat. What does DFCO mean it the ECM constant table? I have been using WinBin so some of the constants might have different names.I am using the $6E code.
Thanks, Tom

I think that is Decel Fuel Cut Off. when you are decelerating, (high map, high speed, or maybe slowing rate of speed), if the ecm does not turn off the fuel it will load up & back fire through the exhaust. kinda like Billy Bob jimmy jacks, 19 and 65 chevrolet pickum up with them thar chery bomb muffins.
thats my cousin btw.

Also, on some applications you need to rework it so that the engine doesn't stall on over run, like with a small converter, on turbo'd motor can be used as an anti-lag strategy.
Ya, my GN has a crackle on overrun. Just means I'm already on the pipe, and don't have to wait around for any **turbo lag**...
