Decided to pull the tune in the cruze and poke around just to see what it looked like. Saw a few things in there different from some other stock tunes that I've seen, particularly the DFCO table. It has minimum time settings at 255 seconds. So if I understand this correctly, this means the entire time I've owned this car it's never used a feature I thought all GM cars came with now? Ive attached a screenshot of the table. What do you guys think?

I'm leery on tuning this car as it is my commuter and I don't want to void the warranty, but this just sucks.

DFCO has been around a long time. GM probably has it off for fuel mileage and drive-ability. I've noticed in tuning that DFCO is more aggressive in trucks and more aggressive in trucks with HD tow options. Works as a good engine brake.

While driving in city interstate traffic like 45-65-45 etc... no load the DFCO was a pain in the ass as it was always coming on while I was coasting, so instead of coasting I had to accelerate...
