The GMC Canyon AT4 / AT4X speedometer calibration device calibrates the speed to ensure a precise speed display on your car after installing new rims or tires. Upgrading to a new tire might be tempting as it can optimize the driving performance; however, it can also affect the accuracy of the speedometer display. If the wheel diameter changes, the displayed speed will deviate from the actual speed. Consequently, this deviation will result in incorrect mileage and can cause problems when passing the MOT inspection. The provider may require an adjustment if the tire size is changed. Otherwise, you may not be able to obtain the certificate for your vehicle.

GMC Canyon AT4 / AT4X speedometer calibration makes it easy to precisely calibrate the speed signal on your digital speedo to comply with legal requirements and pass the inspection for MOT, DMV, or other technical authorities. Installation is straightforward and ensures that the speedometer display is accurately adjusted so that your auto can be used in accordance with the law after modifications.
The calibrator is particularly necessary when motorhomes, Vans, or other types of vehicles are equipped with larger and more resilient tires. The change in the circumference of the wheel affects not only the speedometer and odometer display but also electronic systems such as ABS and ESP. Calibration after making such major adjustments is pivotal to ensure compliance with legal requirements.

If you consider the complexity of your automobile, there’s more than meets the eye. The ABS/ESP control unit transmits the speed signal to the instrument cluster via the CAN bus system. GMC Canyon AT4 / AT4X speedometer calibration is installed in front of it, and a speed, as well as an odometer, are adjusted in real time.
Our module ensures that the speedometer, ABS, and ESP continue to work correctly. Furthermore, our gadget has a plug-and-play interface and can be installed easily. You just have to plug it in, and you won’t need to do anything else. This is the best and most cost-efficient solution, making MOT approval considerably easier.

Firstly and most importantly, GMC Canyon AT4 / AT4X speedometer calibration comes in handy to make sure that your car records the correct mileage and that it appears clean in the MOT report. You can count on this unique device to adjust the speed based on the tire size and avoid going to the service centers that may charge you extra and keep you waiting unnecessarily.
Secondly, unless you conducted the test drive and know what the deviation is, you may get a speeding ticket and endanger yourself and others by speeding inadvertently. In some cars, small speed deviation will not be noticeable until you make a displeasing revelation from the received ticket.

The original wheel speed signals remain unchanged so that the function of the ABS/ESP control unit is not impaired.

The speed display may deviate when changing to larger or smaller tires. For example, if you change from a standard tire size to a larger model, the speedometer will often show a lower speed than you are actually driving.
GMC Canyon AT4 / AT4X speedometer calibration corrects this deviation and ensures that the speed display works accurately as before. This is pivotal for road safety and compliance with legal requirements.
