I recently put bigger tires and lifted my F150. When i did that the speedometer and navigation was off. After a bit of research i was lead to this speedometer calibrator. Once i received it, it was easy to use. Just follow the prompts. Within about 5 minutes it was done and my speedometer was dead on and also fixed the issue with the navigation being off( Nav runs off of speedometer and GPS signal) I would definitely recommend this item.

Purchased this after having my son's truck lifted with 35" tires. We wanted to capture his desire to have the look of a big truck while still maintaining the correct speedometer readings and transmission shift points. The system does require you to use a Windows based PC to update the unit to the most recent software package (it is not Mac compatible), but other than that it is very straight forward to use. Hook it to the OBD port, input your tire size and allow it to update your ECM, that's it.

Great product very intuitive for installation and programming on my vehicle. I installed and finished updating my ECU in less then 5 minutes. Only downside I wish the calibrator did up to 35 inch tires but that's not really a major issue. Overall the hypertech did its job so im happy.

Finally, something that works!

I'm not young, and I've been a car, truck and jeep enthusiast for a very long time. I bought a new 2013 Ford F150 a few months ago and immediately replaced the tires - nothing radical, I changed to the larger factory option. I took it to two dealers trying to get the speedo calibrated. Their equipment showed their changes were accepted but the speedo was unchanged. After spending $135 at one and $65 at the other (and wasted all that time) I bought the hypertech unit and fixed it with no drama

Took me a while to get it dialed in. I originally used the tire diameter from manufacturer. Speedo was still off. I eventually just started entering in different diameters & checking it with GPS. So it does work you just may have to play with it to get it right. I will say I haven't measured the diameter of tires myself. that may explain it. I do think it is a little pricey for what it is but no one else has anything to compete with it. I went from stock to 295/20 Nitto Terra Grapplers.
