Hey mike, have you heard of after puting a tune on it messes up the cruise control? 2005 wk 5.7l
Thanks

I cleared the codes, so i dont know. Im going to finish rhis work week then get into it friday morning. Ill post codes if the battery dis connect does not work.
By chance have the T-1000 messed with the cruise control on the 2005 or other 5.7l jeep grand Cherokees? It either does not work at all or ...

Can i get a more in-depth answer on how to fix this? Chrysler bulletin? Can i use the tuner?
Thanks

Sounds like it. I did not even try to drive it. I just got the t-1000 yesterday, it had me update or calibrate the pcm, then it let me put the tune on. I reinstall stock tune to put the 1r13k 05-10 chrysler gas revision on it instead of the 1r13 mega crom. All my engine lights are off, the t-1000 ...

I re-installed the stock tune 2005 jeep Grand Cherokee 5.7l to update the T-1000. The jeep ran terrible and threw 4 different pcm codes. Updated and re-installed tune its fine. Can not clear pcm codes. Why was the stock tune messed up? How to fix this.
Thanks.
