I just bought a 2009 Dodge Challenger with the Hemi. The car came with a Predator U7135 tuner and I have no idea what I'm doing with it. I wanted to try and turn off the MDS system.
So I plugged it in and went to performance tunes and it says "feature not supported for this vehicle, reflash might be required, call tech support with CALID" Where do I go from here? How do I go about disabling the MDS?
Also I didn't know the car had a tuner so filled up with 87 octane gas. Then on the tuner it said last tune written was a 91 octane tune. So I selected restore original back up. Does this mean the vehicle is back to stock? Did I mess up by filling up with 87 octane gas?
I attached pictures of the message I got when going to performance tunes. If anyone can help me out I would greatly appreciate it, Thanks.

Re: Predator U7135 Help
Im guessing it did not allow you to return to stock either?
Seems to me it was tuned to the 91 octane tune, then someone likely traded it in, dealer flashed it to latest stock cal from Dodge and tool is still married to the old calibration.
Few thoughts. Tool is super old and would be best traded in toward a new device for the 25% discount.
Also, your new Hemi didn't do anything mean to you, so please don't feed it 87 octane fuel
They do not run well on 87, will knock like crazy, and any performance tuning is designed for a min of 91 octane.
