At one time DFCO did disable on this same ecm im using. I running an 03 auto ecm with an 04 manual tune flashed on to it. I have Enable RPM set to the max 6375 and also have Enable VSS to 255. When I'm logging and I let off the throttle it pegs 20.1 on the wideband. Any info will very much be appreciated.
Thanks,
Bryan
