Ford F-450 Super Duty Speedometer Adapters

If you’ve installed tires that are larger or smaller than original equipment tires, or if you have installed a ring and pinion gear set with a different rear gear ratio, the Max Energy Spectrum allows you to re-program for correct speedometer readings, as well as correct part-throttle shifting. The vehicle’s computer calculates your vehicle’s speed based on the diameter of the stock tires. If you’ve installed taller or shorter tires, or changed the rear gear ratio, the vehicle’s computer doesn’t know how fast your vehicle is going. As a result, the automatic transmission may not shift correctly and the speedometer readings will not be accurate (as required by law).

Product Features:

• Speedometer correction for multiple tire sizes
• Adjustable tire size/gear ratio change
• Return back to factory settings
• Reads/Displays/Clears Diagnostic Trouble Codes (DTC’s)
• Internet updateable

Hypertech’s In-line Speedometer Calibrator Module is an in-line module to correct the speedometer and odometer for non-stock tire sizes and/or rear gear ratios. This module is perfect for vehicles with computers that don’t allow for tire size and/or rear gear ratio correction or re-calibrate for tire sizes and/or rear gear ratios outside the range of programmers. If you’ve installed tires that are larger or smaller than original equipment tires, or if you have installed a ring and pinion gear set with a different rear gear ratio, the Speedometer Calibrator allows you to correct speedometer and odometer readings. The vehicle’s computer calculates your vehicle’s speed based on the diameter of the stock tires. If you’ve installed taller or shorter tires, or changed the rear gear ratio, the vehicle’s computer doesn’t know how fast your vehicle is going. As a result, the speedometer readings will not be accurate (as required by law). Using the USB cable connect, the In-line Speedometer Calibrator Module to your PC and enter the new tire height and/or rear gear ratio. There are no limitations for increasing tire height or rear gear ratios. Next, disconnect the factory connector to the instrument cluster (behind the dash), snap in the Speedometer Calibrator Module, reconnect the cluster, and you’re done! In a matter of minutes, you can accurately correct your speedometer and odometer readings (as required by law).

Product Features:

• Perfect for vehicles with computers that don’t allow for tire size and/or rear gear ratio correction or re-calibrate for tire sizes and/or rear gear ratios outside the range of programmers.
• Inline speedometer correction device installs easily to the factory wiring harness
• Use to recalibrate after tire/gear change
• Return back to factory settings
• Reads/Displays/Clears Diagnostic Trouble Codes (DTC’s)
• Internet updateable
