Range Technology Beta Testing

[AXE]

It's becoming clear to me that I'm gonna have to install one of these in my ZR2 to see what happens. I've got a lifetime average over 12k miles of 12.1 mpg in my ZR2. I've gotten 26 mpg over 50 miles and I've gotten 5 mpg off road. Since it seems to help the Tahoe, we'll see if it can overcome the horrible aero package in the ZR2 and my driving habits.

With the dfm range installed was there a change in transmission shifts? In my 2017 there was a change for the worse. Anyone have issues?

Not that I have noticed.

The Range impacts the ECM, not the TCM.
