Rough Country Speedometer Calibration Tool?

[West1]

Rough Country has a speedometer calibration tool listed for sale. It is specifically for the F-150 but they say it will also work on the Bronco. I was wondering if anyone has used this device? For those who have upgraded wheels/tires how have you recalibrated your speedometer after the upgrade?

I know this is an old post, but did you try it? I just ordered it and am praying it works!

Just for the record, I watched a video on installing that rough country calibrator and backed out. Ordered an obd2 connector and used forscan. I had no experience with anything like it before but it was easy. Way easier than I thought.

We did the forscan method in both of ours. It looked like you have to remove the dash display to install it. If I watched the right video.

Yes I think it was actually for the hypertech one, but it's basically the same thing. I'll pass on taking apart that much of the dash!
