Adjusting DFCO
Decided to play with DFCO in an attempt to smooth out some cam surge.
It was originally set to enable @ 1400 (which I believe means anything above 1400?) and disable at 1200. I changed those numbers to 2000 and 1500, respectively. Seems to have helped some, or perhaps improved only in my head. I am trying to reduce a surge/buck as I decelerate in gear clutch engaged. Something like coming down to a stop in 3rd without downshifting and declutching around 1500 rpm before stopping.
Am I doing the right things with DFCO? Anything else to try?
did we not have a scan/tune section years ago? I thought we did and it since has disappeared.

I need to check to see if there is a min MPH for DFCO to be disabled. Maybe it’s just too low for my liking. Have no issues at speed, it’s just under ~15mph stuff where I can feel the engine kick sometimes.
