Please provide your TIPM calibrations. Need to have a scan tool that will read the TIPM.

When I took my 2012 RAM 6.7, auto with 34 gal tank to the dealer for an update (dont ever go to dealer) my once accurate EVIC is now off between 1-2 mpg.

They want $100 to look at it. I've done some research and looks like I can buy Alpha OBD app on google play and Bluetooth adapter to access and change TIPM settings which I suspect were changed by dealer flash.

Please only post if you have an accurate EVIC to avoid confusion.
