Hey Sir,
I wanted to thank you for your input in all this, I really do have it dialed in and the shifts are GREAT, early and really smooth anything less then 55% throttle.
I am still struggling a little with an item or two that would certainly feel better (to me I think) and possibly help a tad more mpg. The factory tune yielded under 11 avg. it was like 10.6. I am up to 11.8 to 11.9, again it is very average as where I live there are a dozen different speed limits within a 5 mile radius and US 31 is a mile away too. As well, I do have a bit of a heavy foot when just tooling around. My best HWY on a 32 mile stretch is under 18, like 16.8 to 17.6, depends on cruising speeds.
The DFCO is one of them. I understand its purpose I believe, but seem clueless on setting it properly (or to my taste) as I am still getting some "engine brake feeling" in a couple spots as I coast down, and the first is immediately after you lift completely at any speed over 45, for a second, (more seconds at higher speeds it seems), but still only a few, then it coasts well til down about 29 to 32 (maybe a couple lower), then coasts well again just a few seconds after.
To best describe the feeling, is like lifting at a mid range rpm in a manual trans in a lower gear.
I'd love to find more info on this setting if you know of anything, maybe have a link or even a "tuner type video" as I've learned a "BOATLOAD" from several of those.
Thanks again, Merry Christmas and Happy Holidays!
p.s. You never did tell me your first name, I call you Mr. Squirrel............ lol
