DFCO fuel cutoff tables?

[Firebirdjones]

I think it's called DFCO? I need to look again,,,but anyway...there are a ton of tables in that area to look at, almost overwhelming.

Is anyone familiar with adjusting the tables to be more aggressive on fuel cutoff when coasting? It was one of the fuel saving ideas talked about in years past but I never explored it. I remember reading in the factory tunes it's rather mild and doesn't kick on until after you are off the gas for a long period of time, something like 15-20 seconds. People were picking up several mpg by making this function more aggressive.

I'd like some tips or pointers if anyone has experience with it. Thanks.

Where are all the savy tuners? Frost around anymore?

I've never messed with those tables other than for SD tuning.

What would they have to do with SD tuning? I run all of our LS vehicles in SD now but I've never touched the DFCO in any of them.

Got a handle on it now.

sorry....missed your reply. Glad you got it figured out. I've always disabled dfco when sd tuning so it doesn't skew the numbers.
