Hi everybody, I'm having issues with my tune, doesn't matters if I modify something as simple as the torque limiter or the whole upshift pressures and slip parameters... it's the same unless I put the stock file...
There is a transmission DTC I should disable?
The codes I'm getting after the TCM flash are U0140 U0402 U11BC ...
I'd really appreciate your help...
Some of the torque limiting tables can give you strange errors.
Make double-sure that stuff is back to stock by starting over with your stock file before making changes. Just changing the numbers back doesn't always work right.
If in doubt, multiply everything by 1.1.
I put the stock file and works good right away... but it doesn't matter what number I modify, my tcm or my jeep srt doesn't want anything different than the stock file...
srt eli 6.4 Supercharged 091920 tcm.hptsrt eli 6.4 Supercharged 091920 tcm modded 2.hpt
stock TCM file is the one that says 091920 TCM the other is one of the modded files I made with no luck
Coming at this way late, but I just wrote a tune to my SRT grand cherokee, and the same thing happened. Did you ever resolve this?
post tune and log
Still working my way through it, but it appears in my case that adjusting the max torque limit is what's causing my issue.
Could you share the latest tune?Originally Posted by Chubby Racer

I'm having this same problem in a 21" ScatPack. Any ideas here? Did you ever get it fixed?
