I tuned an 08 LMM and at the same time I corrected for his tire size as the speedo was off about 10%. I thought everything was ok but when he took it home he noticed that it down shifted really easily on a small hill. When he brought it back I test drove it and it definitely isn't right. After fooling around with several aspects of the tune I finally figured out that it was the speedo change that is effecting it. It seems like the cruise is seeing too much speed loss for some reason.
Resume is also terrible. IF you set the cruise at 60mph and slow down to 30mph and hit resume it will speed up, down shift, up shift, down shift, etc.
Either I am overlooking something or something was perhaps overlooked by EFI Live?
