The A9L does effectively disable the DFSO by extending the time intervals til activation to 31 seconds (I think?). I have not checked on the other A9* series stuff, but would guess it to be more of the same.
The X3Z is actually quite aggressive in cutting fuel on decel, probably for the reasons you stated above - Roush having to pass emissions on the first go.
I had very little luck messing with the tip-in stuff.
The DFSO settings did make a major difference though.

In my mind there is a difference between lean on tip-in, and remaining lean after a short closed throttle decel or a shift.
It seems that it is fairly common to have issues with lean on tip-in, but very few have had to mess with the DFSO settings.
I could be wrong though, I still feel like a noob with CalEdit.

Actually, it is quite a bit longer than that. 200+ seconds, IIRC. Effectively eliminating it's usage all together. Ford software engineers couldn't get it to implement well - it caused bucking when activated (imagine that).

I think I know what Scalar you are thinking of.
That same setting is used for the X3Z though, and the X3Z does cut fuel on decel.

Here is a table I put together and posted on another site.
I haven't had much of a response so maybe you guys can offer some input?

I cannot claim to fully understand all of these settings, but I am trying.
The colored cells are the ones I have had the best results with.

Nor have I...

Well, I messed with all of them except the shift ones. Couldn't find a satisfactory compromise so just locked out the function like Ford did.

YMMV, Don
