Please Help with TCM tune
I have a 2012 Jeep JKUR with an edelbrock supercharger. since the SC the transmission holds 2nd gear and 3rd gear. I have changed the shift scheduling part throttle rpms and it does not fix the problem. It shifts great under %30 throttle. But when I start from a stop and give %35-%40 throttle it will hold 2nd gear until 5500 rpms. The MAP starts dropping at 3900 rpms which is when it should shift. My Tranny shaft rpm is at 1700ish. So according to my shift schedule tables it should shift but does not.
I am new to tuning and have been doing so much homework lately trying to learn. Just need a little guidance on what I am missing here???:banghead:
