What speedo calibrator for 2020 with park assist?

[Spidartanks]

I had a rough country one but it won’t work with the park assist
I have a 6” lift and 35’s. My oem had the 22s so my speedo is off by a few kmh
I would like for it to be right

what calibrator tools work? I just read about the auto calibration feature which seems like a bust. Does the tazer model keep the park sense and re calibrate ? Thanks

the dealer said they have to buy a code from Chrysler for $250
If I’m paying that I’d rather buy my own and Change it for if I go to 37s too

thanks for the help

first post here but I’ve been reading lots since got the truck last July. Cheers

I did some research on the Tazer DT
But does this speedo calibration work with the park sense system on the ram, I’d like to keep the option available to me still

I did purchase the rough country one and it loses the park assist feature

When I contacted Tazer they said the trouble with park assist happened with tires over 35". At least that's what users reported to them. They haven't had a '21 in the shop to thoroughly test.

I got an answer back from them too over txt.
Seems to be an issue on 2021’s over 35 inches. Haven’t had trouble on 2020 that I know of

So for my 2020 ram it should be completely operational

also there is a 30 day moment back guarantee

the only thing I find odd about this module is how you unplug 2 plugs from
Under the dash and just plug in the tazer unit.

It works but I find it odd how those 2 harnesses are now unused and just there
