Speedometer Calibration

[Hornet4096]

I just purchased a ‘24 1500 w/5.7. It has a 6” lift and 35’s. I need to calibrate the speedometer to the 35’s. Can anyone recommend a tuner that will allow me to do so?

AlfaOBD can do it to plus a lot of other stuff.

I have the Tazer on my truck running 35s as well

Tazer. Did my speedo with bigger tires in a few minutes. Doesn’t get any easier than that.
Lot’s of other options to use it for as well.

Does the Tazer need to stay plugged in for changes to stay?

 

[Hornet4096]

Thank you for the feedback!

No the changes stay. You might want to go to Z automotive web cite go to firmware and then go to manuale and you can look at all the things you can do with the Tazer.

Thanks for the info, I'm gonna go with Tazer or AlfaOBD
Dealer quoted me 345.00 to calibrate to 35s and I had to buy a service contract ?

do you have to get bypass cables or anything else with the tazer? I think with the Alpha you have to get a couple things besides

No, I did get the SGW Extension Cable so I don't have to try and get my fat hands up there.

Ultimate OBD JScan Thread

We have very extensive AlfaODB thread so I thought maybe it is time to start one for JScan? Seems JScan is slowly getting upgraded in what it can do and I am an Apple world guy so it is my only option right now. I don't mind buying an Android, but if I can use what I already have why not? I...

will the alphaobd work on a 2022 limited with the OBDlink LX? I just read that whole page and I'm confused on what works and what to get.
It seems that to use the LX I need the blue adapter. But I don't know what to search on in Amazon, searching for blue adapter returns all sorts of interesting stuff. I just want to recalibrate the tire/wheel size.

Yes. Alpha or Jscan, the OBD2 adapter, and an SGW bypass cable. Jscan also requires a one time license fee to unlock the VIN for you to make changes. Not sure about Alpha
