A software tool that assists in determining appropriate circumference settings for a vehicle’s onboard computer when modifications to tire size are implemented. Accurate modification of this setting is crucial for proper speedometer calibration and transmission shift point management. An example of its use would be recalibrating a vehicle’s computer after installing larger tires to ensure accurate speed readings. This action directly impacts the accuracy of the speedometer and odometer.
Implementing correct tire size settings contributes to the vehicle’s electronic stability control system operating as intended, and ensures that the transmission shifts optimally for fuel economy and performance. Historically, mechanical means were employed to achieve speedometer calibration. The software solution allows for a more precise and easily adjustable alternative to older methods, like gear replacements within the speedometer assembly. This precision minimizes error and improves overall vehicle operation.
