2021 Speedometer correction attempt?

Anyone try the Rough Country calibrator on a 2021? It claims it is for specific years, and the 2021 is not available yet. Not sure how different it is going to be from 2020 to 2021?

For what its worth, I have the unit on my 2017 and it was pretty easy to calibrate and has been working great for about a year now. I would bet it works just fine on a 2021 if the gauge cluster is the same. someone here will confirm.

 

Try searching "Rough Country calibrator"or "Hypertech speedometer", and see if someone else answers this for you incase you don't get a direct answer. Hypertech and Rough Country calibrators are the same AFAIK, so someone probably has tried to put one on a 21 by now.

 

I bought this one for my 19 and it said it only supported 17-18. It worked not sure why they don't update their info.

 

I just chatted with Rough Country and they said the are not "programmed" for the 2021... They said they are working on it, but have no idea when it will be available.

 

I run the RC calibrator with no issues on my 19'. My friend with a new 21' Taco installed on his and hasn't had issues that I know of yet, but maybe he can chime in to confirm. @TacoTim85

 

They told me the same thing and I never heard back. I don't think there is any difference between a 18 and a 21 computer wise.
