Help to get larger tires calibrated with speedometer on 2021 Power Wagon

[Whitetaildeer13]

Hey guys, would anyone be able to tell me all of the products I will need to calibrate my speedometer with my larger tires On a 2021 PW? Thanks in advance.

I used AEV procal snap. Many users on here are savvy with Alpha obd as well

There are a ton of threads on this. 2019+ are all the same.

AEV Procal, AlfaODB and Ram Tazer are all products you can search for on the forums and will do what you are asking.

All 2019+ trucks need a security gateway module bypass cable.

AEV Procal and Ram Tazer are both simple to use.

AlfaOBD takes a few more steps but is more powerful in enabling other features on your truck.

Happy searching.

Rough Country calibrator works too. I used the one I had from my 5th gen 1500. Worked fine and comes with everything you need.

Is there a sticky somewhere that has the command and places to go within AlfaODB to turn on/off the popular features?

Ive watched a few vids on it and there is sooooo much in there, i dont know how anyone finds the specific thing they are looking for.

Yes

I'm probably going to put 35's on my 19 pretty soon. I'll let you know how it goes with the recal.

I already lowered the TPMS threshold to 40 psi with alfaobd. Kind of wanted to make sure I could do it before I bought the tires.

Hope to get the tires next month.

I installed 35's (34.6) on Saturday and got around to playing with the Tazer Ram last night. It took me a little longer than I expected to get it right, but it is pretty straightforward to use. I adjusted the tire size and the TPMS settings along with a couple of other items.

Their product page says you still have to visit the dealer to adjust the TPMS settings and have the vehicle recognize the changes from the Tazer. Did you have to do that?

Or did you disable the TPMS altogether?

I read that part and decided to try it anyways. The changes seem to have stuck without the PIN. They have three different settings for the TPMS NONE, BASE and PREM. I left mine on PREM and adjusted the tire pressure threshold down for front and rear. I did a couple of reboots and this morning, my tire pressure low indicator light was off on the way to work while showing 53 psi front and 48 psi rear. So, it seems to have done what I wanted it to do.

Awesome! It has some other features I like so I might swap out my rough country calibrator for the Tazer.

Anyone know the best way to get the KODtech white can blocks back out? I cannot get them out with a screen driver for the life of me.

I use a small pick to press the release button while pushing in on the plug. If you are pulling out on the plug while trying to release the lock, it wont work.
I finally, after fighting the locks a lot, jut cut them off. So now I can install and remove the plugs with ease.
