I was wondering if anyone else has the same problem that I do. When DFCO is enabled, the tcc is locked. When I press on the brake, the tcc unlocks immediately and DFCO stays active. This causes an extreme drop in rpm and the motor has to catch itself from stalling. I guess it's not really a problem, but it annoys the hell out of me. Why doesn't hp tuners have a way to deactivate DFCO when the brake is applied? Isn't that how the factory tunes DFCO?

You can modify the dfco entry and exit settings...but add some more advance during dfco to prevent the big drop in rpm

Yea all the entry and exit settings are changed to how I like them. I just don't like the big drop. How much advance are you running during dfco? Mine goes to 0 advance. Should it be more around 10 degrees?

When I slow down and hit around 42mph my DFCO kicks in and it does acouple jerks and it annoys the **** out of me!

It looks like the active spark tables arent used. Why is that? Does it only use the entry and exit spark tables?

It uses the "Spark Advance Table A/B" in the "DFCO Active Spark" section.

Yea those are the tables I'm referring to. Under each table it shows a throttle position percentage that must be exceeded before that table is used. On all the tunes I've seen, those percentages are 99 and 100%.

Yea, I think they defined it wrong, mine uses the b table

Thanks man. I will see if I get that drastic drop with higher spark advance.
