I need a tire size calibration for my new style 19 1500 4x4. I been thru the original Edge Pulsar. 3 to be exact. I had the typical dash lights flip out and it goes into limp mode. I haven't tried the newer version yet. I did like it because I actually picked up a couple mpg from it.

The Tazer DT was fine until I adjusted my tire size then it would turn off my front and rear parking sensors. I tried many times but I had it sent back and refunded. No mpg change really after adjusted so the Pulsar did seem to make legit games.
The dealer tried but can't do it.

Flashcal isn't made for above 2016 Rams.

Rough Country may work but I think I read where it won't work on Rams with parking assist.
So for the new style guys, what are you using and your experience?

I have a 2019 2500 I just put bigger tires on (35s). I used the Hypertech speedo calibrator. It was stupid easy to use. Plug into OBD and a wire going to the green BCM bus bar...couple key ons and key offs and got it dialed in.

That said...I just added AlphaOBD to my tool kit and plan to undo the hypertech settings and redo them with the AlphaOBD. Hopefully I can unpair the hyper tech from my truck and sell it on the used market to recoup some expense.

I just came across the alphaOBD and I'm reading up on it. May be the way to go since it has so many functions.
