1999 Formula WS6 M6-sold- 2001 Silverado Z71
I started playing around the DFCO (Decel Fuel Cut Off) settings to make it come on a little more often and see if it'll give me a MPG boost. I'm also thinking about running open loop and leaning out the cruise areas for better mileage. It seems to correct back to stoich when I make changes and run closed loop.

Those two things give me the biggest mpg gains. DFCO wasn't even working on my wifes car, the rpm activation rpm was never reached during normal cruise.
I keep it in open loop and command the AFR I want in the light throttle cruise areas. Had my wife car this way for a couple years now.

yah, the stock DFCO settings were nearly worthless on my truck too. I lowered the rpm (so it'll come on when I'm above that), raised the MAP sensor enable (so it'll come on sooner), and messed around with the spark enable and mulitpliers (again so it'll get into DFCO sooner). I can feel it working now. I let off the throttle at 70mph...it coasts for a second or so...then the fuel shuts off and it feels like its engine braking. I'm gonna play with it some more.

That sounds like the off RPM's probably need some tweaking so it stays on longer. I set mine as low as I can go without stalling when coming to a complete stop. I think I have my "off" rpm at 1100.
If you get too low the engine will struggle to maintain idle or die because the fuel is still cutoff, especially if you have a cam in it. Just have to play with it till you find what works for yours.

Yessir, mine was a bit high....1600 entry/1000 exit, so I lowered it to 1000/800 to try out.
