Well, here is the latest update, as promised:
Just to be sure you know all the factors involved, I was using the "Trans only" tune in conjunction with my Juice (no Attitude).
Initially, the shifting was great!!
HOWEVER, as I got more miles on her, I started noticing the shifts were all getting firmer the more I drove it, to the point they were down right harsh..... It started out as just the shift into OD being too firm, then the shifts into 2nd and 3rd started becoming harsh too....... I tried backing them down some and was back to the standard setting on the shift to OD. No help at all..... In Tow/Haul, every shift was even more extreme. The weird part was, if you floored it, the shifts were still really nice...... but at anything less than full throttle, they were WAAAAAY to hard. Then, to make matters worse, I went to KC to pick up a horse and on the way back, it started acting really weird..... If my speed dropped at all, (like going down a small grade, then up another one) when I tried to accelerate, it would smoke like a freight train and started bucking really bad.... I mean REALLY BAD!! The whole truck was shaking violently.......
-mad Using the factory programming, it would have downshifted there, but with the Evo in, it was like it was hung in gear and didn't want to downshift...... The further I went, the worse it got. At one point, I was questioning whether or not I was going to make it all the way home or not. When I got home, I returned the tranny to stock programming and took it for a drive..... It seems ok now..... The shifting is back to where it was before.
I have since talked to Edge about it. They had no real answer for what was happening with the bucking situation, but believe the adaptive learning strategy of the tranny may be what caused the harsh shifting. According to them, the standard "Trans only" tune has already raised the line pressure somewhere between 5% and 10%. They told me to try re-installing the "trans only" tune and leave all the pressure settings except the shift to OD at the standard setting and back that one down to either -5% or -10%. They also said if I continue to have the problem, to get back with them and they will send me a different Evo to try, because they believe it would have to be in my particular programmer if it continues to be a problem.
I will try their suggestion and see what happens and report back on what I learn.
UPDATE: I tried their suggestions last night and drove it for quite a while. It seemed to help, but as I was experimenting with different settings, I ended up getting an error message saying "Programming interrupted". Fortunately, I had the stock programming re-installed at the time. I called Edge today and they are shipping me a new Evo out to try. Gotta hand it to them, they are certainly doing all they can at this point.
I will again update when I get the new one.
