🏎️ Hypertech 730123 Speedometer Calibrator: Accurately Calibrate with Ease Review

Tacoma's essential tool for changing tire sizes. The instructions are a bit difficult to understand. I was told to measure the distance from the ground to the top of the tire, not the size

Dashboard is easy to remove, cable is easy to install, programming tire sizes in cable assembly is also easy before installation. The speedometer is on top compared to the GPS.

I increased the size of the tires and needed a more accurate speedometer so the odometer reading and estimated fuel consumption were closer. It did everything by simply entering the original and new tire sizes. I tested it on my Garmin and it was fully functional.

Plug and play, easy installation and connection to Tacoma, I recommend. I have 35th and 5.29. Gear I put the transmission part in the computer and when I connected it to the truck I took the transmission part out just measured the tire difference and accurate by GPS mph.

Easy to install with great results. The initial programming of the module was a bit tricky, so I called Hypertech support. You walked me straight through my problem. My speedo is dead to 45 mph now and about 1 mph at 60 mph (according to the GPS on my phone).

Very easy to install, not as scary as I thought it will take my 2019 Tacoma dashboard apart and pre-program new tire height measurements with a tape measure and then I just disconnect the straps that go right there and slide the Hypertech into the original seat belts and dash, pull back backwards and you're done! 🌮☕👍

Fitted bigger tires and wanted to fix speedometer and odometer. Since this is the only device I could find for the Tacoma, I was a bit skeptical. But it did its job well. Programming and installation each took about 15-20 minutes. I checked the GPS speed before and after the big tires. At a speed of 50 km/h the difference was about 4 km/h. Programmed and installed by Hypertech and it works with GPS again!

I have 33" tires on my 2016 Tacoma V6 4x4. The truck didn't feel sluggish with the tires, but the speedo was 10% slower than mine (less than my actual speed). Shift points should be off and fuel consumption fluctuate. After installation there was a noticeable difference in handling and it now feels 100% smoother and at the right time shifting and gas mileage has increased. I get 19mpg.
