Looking for some help to figure out why the car isn't going into DFCO. Seems that all the parameters are met but in the scanner im not seeing the pw and timing drop accordingly/not feeling it in the car. Have done this on other cars but for some reason on my own it won't work.
Any ideas are welcome.
Scan and tune are attached.

anybody?
trucke55.hpttrucke55.hpt here is my tune and dfco works well
My setup is a 356ci with a 260/268 (212/218 at .050 lift) duration cam with aluminium corvette heads and flat top pistons running 11.3 comp. ratio. with tuned port injection and vortec crank pick up and dizzy running a 411 pcm and 60lb bosch injectors, 1.6 ratio roller rockers.For transmission its a 4l65e built with the monster in a box mega ss kit.
All in a 92 chevy ext cab 4x4 pickup with a 98 cab now installed with a third door!
running only e85
Yeah but those MAP settings won't work for me since my cruise and off throttle map values are different. I'm looking for any advice on why mine isn't working based off log and tune
Do you have functioning clutch switch, as I see that you set P0704 to no error reported? As with an open switch, the PCM thinks that the clutch pedal is pressed, thus the DFCO won't enable. Also return the DFCO Enable Clutch Transition tables to stock as I never touch them and have no issues with DFCO not enabling.

Russ, I don't have a functioning clutch switch. It was never adjusted years back after I put in a tick master. If i switch it from no error reported to just no ses, will the DFCO work? I figured it had to be something stupid like that.
Like I said, the DFCO won't enable without a functioning clutch switch.

looks like its time to fix the clutch switch. Thanks for the help, it was driving me up a wall.
Russ, fixed the switch and everything works perfectly. Thanks for the help
