Keep your calibrations in check with the Hypertech Speedometer Calibrator. Monster mudders, custom rims and aftermarket gear swaps are great for your rig's performance and style, but the vehicle's brain still thinks you’re rolling stock. And, that means your odometer and speedometer calibrations are way off.
To instantly dial-in your speedometer and odometer, the Hypertech Speedometer Calibrator plugs into your OBD-II port, or the in-line module connects right to your instrument cluster. No more false mileage added to your tumblers which affects resale value. And, no more blasting the speed limit—by accident of course—which leads to expensive speeding tickets.
Beyond keeping your speedo in check, the Hypertech Speedometer Calibrator also reads and clears annoying trouble codes—putting an end to costly diagnostic work (inline module does not). Plus, your Calibrator is easy to update, via the internet, so you always have the latest and greatest programs. And best yet, your Hypertech Speedometer Calibrator is backed by a Lifetime Warranty.
Thanks to the Magnuson Moss Warranty Act: US Code – Title 15, Chapter 50, Sections 2301-2312, your vehicle’s factory warranty is protected by law when you add aftermarket parts. Details

I was a little disappointed that for the price it isn't more accurate, my tire size is 25.31" and the calibrator only calibrates in 1/4" increments so when I pass the several radar signs on my way to work each day I am still off by 1 mph on my speedometer. I have calibrated it for 25.25", if I calibrate it for 25.50" then it is off by 1 mph the other direction. It is better than the 5 mph difference that I was originally seeing but for the price could be better.

Overall, I'm very satisfied with this speedometer calibrator. Initial setup and software update is a little clunky but I'm no tech wizard and I figured it out. Install in my truck was simple and the items works as advertised.

Worked like it was supposed to after installing larger tires. I compared my speedometer to my GPS before and after I installed it. Very happy to not have to worry about the difference in speed.

As easy as it looks I plugged it in and the first thing it told me was I need to update it for my vehicle. I am very busy chasing kids around and work. I was very dissatisfied after giving my vehicle info and did not work. When I find some time to get it updated I will use it.

Bought to recalibrate speedometer to improve mileage, trans shift at correct RPMs, and accuracy back to stock-- it did this exactly as product was described. Very effective, very easy to use which is a big plus!

Easy to use. Accurate. It's nice having my speedo and odometer read correctly with a bigger tire. I'm going to regear here soon so it will get some more use when I do that. Worth the price.

Once the calibration has been done, can the unit be removed and calibration remains? Or does the system need to be in place to maintain the changes?

The Speedometer Calibrator is never connected to the vehicle while the engine is running. The key is on and the engine is off during the programming process. Once programming is completed you'll disconnect the unit. You can reconnect to return to stock or make changes when needed.flag Accept Answer
