Default Need tune file(s) please

I'm giving my decel issue another go today and have my sights aimed on my DFCO parameters. I've read every thread I can find on tuning DFCO across multiple forums so far and I'm coming across a lot of conflicting info as well as lack of specific detail, but I've got some decent info overall I think. I'm going to tinker with a few parameters, but also wanted to see if anyone would care to share any hp tuners files they have for a stock motor 6 spd with an A&A setup. Blower, pulley, injector specifics don't really matter as I would just like to compare/review the DFCO section.

Well, I didn't change them because I saw no reason to do that.

In some cases with wild cams and C6/E38 platform I tend to modify them to activate earlier.

What is your specific issue you're trying to fix?

Thanks for the reply. I actually resolved the issue the other day by successfully adjusting the parameters. I wish I knew exactly which parameter resolved it, but I figured I'd make other adjustments at the same time to kill 2 birds with 1 stone.

I was basically experiencing a light bucking/surging on decel at a couple rpm ranges intermittently, but at 1500 rpm without fail. Nothing insane, just enough to be annoying and inconvenient during a normal drive. After that only expert advice I had actually received told me it just had to be the used injectors I was using, I figured I'd try to hunt it down myself since my gut told me injectors weren't the issue. Finally figured out what I was feeling was actually DFCO turning off (injectors kicking back on after being off). I've got DFCO set to activate earlier now (1400 rpm vs 1800) and last longer (off at 1100 rpm rather than 1500). Greg Banish chimed in on my other thread in scan and tune and said it was probably the ported TB causing the transition to be more noticeable, which it may be, but lowering it closer to when I'm pushing the clutch anyway in is much better than having it interrupt decel from a higher rpm 👍

Exactly and I've done that too when necessary!
