That guy kind of tuned my truck last night but it wont kick down and when i put it on cruise control it jumps up to like 3000 to 3500 rpms and he wont answer his phone to finish it so i am messed up pretty bad.

 

Damn

 

ok i'll ask !!! whos that guy!!!!

 

That is his name on here...'thatguy'...

 

wont kick down period? or just the MPH and RPMS arnt set at a meeting point? Sometimes they 0 out the MPH and do only rpm shifts and that will screw with the kickdowns.

 

i told you haha

 

I mean its like every spot is dead, i stomped it at 25, 35, 40 60 65 and its just dead. The rpms wont move and im just barely moving.. He says he has to do something with shift speed.. Does that sound right?

 

this is why I leave the tuning up to the pro's...

 

HPTuners has a Shift Speed table for mph points the PCM will use to acknowledge an acceptable speed (mph) and engine revolution (rpm) to allow a shift to occur. If those parameters are met, then the shift occurs. RPMs (if not mistaken) is the final "say so". That's obvious b/c if the RPMs are set too low, and the mph point is too high, you'll hit the limit before the mph is reached... thus the vehicle falls on it's face & bouncing the limiter.

As a part of that same table, there are downshift characteristics regarding designated mph points versus throttle position. If your downshift cells are set to "zero" or they're set lower than what you need, then I can understand why you will not get a downshift @ WOT. I hope that is not what was done.

 

listen i didn't half *** ****... i missed one little thing while doing his truck... no reason to ****** bad talk me for a small problem. and 07 keep your fuckn mouth shut.
