Hypertech 730119 Speedometer Calibrator – High-performance Speed Calibration Tool Review

This kit was programmed and installed by a certified contractor. My speedometer was still at 15 mph at 65. I called Hypertech and they said the 2019 has a different computer so the tire size will change, but my speedometer, shift points and estimated range will not change. i give it back

It wasn't difficult to install, the hardest part was programming because entering the gear ratio and tire size made the speedo wider than it was. I had to put the 5.29 gears I have, but the tire size was to put a 41 inch tire instead of a 35. Just so it would match the speed in the GPS app I tested in 3 different apps all came back with the same speed

Installation is easy but takes about 30 minutes. This gives you an accurate speedometer and in turn a reliable mpg value. I haven't changed the gear settings, but it's nice to know they're available. I recommend leaving the USB cable plugged in and hidden behind the steering column for future changes without having to do another full install.

After installing 295/70R18 tires on my 2021 TRD Pro I wanted to put the speedo and shift points back in place. Installation following the instructions downloaded from Hypertech was very easy. Leave the USB cable connected to the device as you will need to play around with the settings to get the correct calibration. I found that when changing from Michelin factory tires to a 295/70R18 Falken Wildpeak AT3 I had to use the "Diameter" setting and set the original tires to 32" and the new tires to…

2014 Toyota Tundra Crew Max: Everything worked as described, speedometer was fine. It took two attempts to get this unit to my house. The first time it got lost in the mail or something and it never showed up. It was quite difficult for me to get the software I needed to calibrate my car. Luckily I was able to find a drive from a previous Hypertech purchase that I used. Otherwise, I'm not sure I could get it to work using the software download site. The installation is quite easy. I removed…

. Hello everyone. Just wanted to let everyone know how this part works. When I first received the part I went and installed the drivers and software that I needed to install. As announced, no disc was included. So I went to their website and set it up. After downloading the program, I launched the application. He kept saying that he couldn't connect to the tuner. After trying 5 or 6 times to get it to work, I read the messages that were in the window above the connection attempt numbers. It…
