cruise control issues

[karnage42]

After installing a tune my cruise is doing weird things. Worked fine before doing the recalibration and cai 91 tune
Now it will only set at 35mph and 55mph. Any other time it shuts off. The brake light switch is fine. It has to be an issue with the tune.

what vehicle?

2005 dodge magnum rt. Never been tuned and i installed the latest calibration for the ecu. Ihear this year has issues when doing a tune

Any idea why this is happening. I notice when firming the shifts the traction control lights come on, then go off
After tune is done. Is cruise affected by traction control.

I am guessing I need to update the firmware for my predator. u7135-9r30. Is this right?? I am having problems with the crom. It saves but doesn't open, cant read
