Speedometer Calibrator

The HYPERTECH Speedometer Calibrator (MPN 742502T) is an electronic tuning module designed for vehicle owners and enthusiasts who require accurate speedometer correction after modifications such as suspension lifts, wheel and tire upgrades, or differential ratio changes. This device addresses the common issue of inaccurate speedometer readings that can occur when a vehicle's rolling diameter or final drive ratio is altered.

The calibrator adjusts the speed signal sent to the instrument cluster, helping to restore accurate speed readouts without the need for costly dashboard replacements. It is designed to be compact, measuring 5.3 x 2.5 x 8.75 inches and weighing only 0.9 lbs, allowing for easy installation under the dashboard or within the center console. The unit uses programmable electronic correction to accommodate changes in tire diameter and gear ratios.

This speedometer calibrator is particularly beneficial for truck and SUV owners who have upgraded to larger tires or lifted their vehicles. It ensures accurate odometer and speedometer readings, which can be crucial for warranty compliance, insurance claims, and monitoring fuel economy.
