U7198 adjustments (upshift MPH vs TP)
Posted: Fri Dec 07, 2007 8:01 pm
I have a custom tune to help the rough shifting and I got my LTFT's dialed in, now the truck runs great. I have not adjusted the PE cuz I do not have a wideband to monitor the setings. I was reading about some of the adjustments that other members have made and someone said that they maxed out the (upshift mph vs tp) setting and it gave him better throttle response. Well I tried this but only changed it to 30% and WOW what a difference! When cruising between 25 and 55 if you step on it ,the truck just wants to go. Normally it would take a second to downshift and then go. After reseaching these boards Johan said that he does not change these peramaters unless you change gears. Will this hurt anything with stock gears? I know that it holds the gears a little longer, but what if any are the down sides of this change?
