DFCO tuning So since my last cam swap, I've noticed that I've not had as much engine assist when slowing down. The reality is I wasn't entering DFCO anymore. On logging I found to hit ~25 kpa on decel.
On the HP tuners forum I found 2 trains of thought, one is go with the decel kpa and run 5 kpa higher.
The other is go with idle kpa.
I've tried the idle one and found there is a delay on re-entry ie a delay on stepping on the gas and the reaction.
I've also noticed there's a "jump" of the car when it hits the exit rpm of DFCO, nothing too serious, but I've alleviated it by putting the exit just a bit higher than idle (900 idle, 1000 exit) since I usually step on the clutch at that point.
Thoughts on DFCO? I will try the decel kpa I've logged and see if it helps that kick back
