i'm looking at buying the PPE Excelerator. does anybody have any experience with this programmer? What are the feelings about PPE? i have heard nothing but good things about them but wanted to ask. Thanks.
Resetting the tranny just means that you have set it to "fast learn" mode. The Allison is a very sophisticated transmission, it constantly reads the driver's input and tries to adjust to your type of driving style. Typically it takes somewhere around 100 miles for it to adjust to something under its normal operation. But with fast learn mode, just like JDiesel said it takes about 25 miles max for it to adjust. I would run a couple of hard passes under the relearn mode so it will become familiar under heavy throttle. Having the tranny relearn for a different power level doesnt mean that it can hold lvl 6 (350hp) it will just try too adapt to the amount of power going through it. The max amount of extra power a stock allison will hold is about 90 hp, so running lvl 3 (160hp) is probably the limit. :blahblah:
I was kindof thinking that myself. I use 225,300 and 350 tunes, Sometimes I don't do the relearn when switching between the 3 tunes and the tranny seems to adjust pretty fast.PPE Hot+2 ET, I have only ever set the trans into relearn twice, I dont feel it is really needed after you have ran the higher HP tunes.
IMO...It's totally different power settings between "level 6" and "level 2" so shifting points would be very different.I was kindof thinking that myself. I use 225,300 and 350 tunes, Sometimes I don't do the relearn when switching between the 3 tunes and the tranny seems to adjust pretty fast.
I've been doing a bit of research about programmers mainly for an MPG increase. I currently get 17 1/2 to 18 1/2 MPG in the city and up around 21-22 MPG on the highway with my 2006 Duramax with the Allison trany.
What kind of mileage are people getting with the PPE programmer or even other models?
When you reset the Taps on your trans the shifts will flare up and the trans will feel weird.. Its best after a relearn to do alot of stop and go driving followed bye runs threw 1/4 throttle then half throttle. Try and avoid WOT untill the trans feels like its shifting normal.
PPe is a great tuner. I would definetly recommend the PPe 2 hot. It gives you a broad range of tunes for a stock transmission or a aftermarket trans. You will not be unhappy in choosing this tuner. PM Dan and he'll take care of you. Their customer service is second to none. He is always on the site and is very available for any problems you might come across.

Did a mileage run couple of weekends ago on lvl 5, 100 miles. Course included flat runs and transmountain routes. Total average was 20.8mpg with GPS miles and pump gallons.I was getting 17 in the city before the PPE.........now I get 19.8 ( hand Calc) on level 2. I have yet to do a roadtrip yet, but that is soon to come. I am expecting to see somewhere around 23-25 mpg.
