Is it a given, that if you take your vehicle in with a CEL, that your ECM is always going to be flashed, even if not related to the CEL?
Wouldn't they read it, replace the part, clear it, and still wouldn't affect the AEM or GDE or whatever you have... or is it pretty much going to be re written just by being connected?

I’m wounding if I got this Could I save original tune? Pre ADM have not gone in for ADM yet! Waiting till last minute!
did you ever figure this out? I am also pre AEM and would like to save that original pre AEM tune. This way I would have the flash tune and the pre AEM tune. Does anyone know if this is possible?

It's possible if you get a tune and tuner with a company that uses a handheld device. Hit up Chris Monro at EcoDiesel owners of Canada and get a MRTuning tune. It will save your original file, and give you the option to switch back and forth between tunes for dealership visits.

2016 summit.

Updated with pc.

Plug into odb. Select dodge, ram, second entry with the Bosch engine code. Select to read stock file. Instructs to turn key to on position. Push button to run, with out actually starting car. Unable to read.

Also tried in acc, off, and running.

Doing something wrong or?
Thanks
If you have a jeep, how come you are going to the Dodge Ram page? Have you tried going Jeep, Grand Cherokee, and then selecting the entry with the Bosch engine code?
