The Hypertech 752503 Speedometer Calibrator for your 2007.5-2017 Dodge 6.7L Cummins can correct the speedometer and odometer for tires up to 44 inches (depending on the application), and/or non-stock rear gear ratios. This device is engineered for consumers that want the speedometer recalibration functions of the Max Energy Programmer without the additional expense of the other tuning features.
The Speedometer Calibrator comes with a USB cable and a CD containing software to enable quick updates and upgrades over the internet. For an additional charge, the Speedometer Calibrator can be upgraded to a Max Energy Power Programmer via the internet to include all the Max Energy features available for that vehicle. Simply plug Hypertechs Speedometer Calibrator into the vehicles under-dash connector, select the new tire height and/or new rear gear ratio, and in a matter of minutes, the vehicles computer is reprogrammed for accurate readings (as required by law).
If youve 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 re-program for correct speedometer and odometer readings, as well as correct part-throttle shifting. The vehicles computer calculates your vehicles speed based on the diameter of the stock tires. If youve installed taller or shorter tires, or changed the rear gear ratio, the vehicles computer doesnt 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).
Read & Clear Diagnostic Trouble Codes (DTCs)
If you get a check engine light or service needed message, the Speedometer Calibrator will allow you to read the code and gives you the ability to clear the code and turn the check engine light off. This allows owners to access information about the vehicles operation without having to purchase expensive diagnostic computers or scanners used by dealership techniciansYou can then make the necessary repairs to prevent the light from coming back on.
Return To Stock Or Change Option Settings
Hypertechs Speedometer Calibrator downloads and saves the stock tuning program, then uploads your customized Speedometer Calibrator program. Before taking your vehicle into a dealership for service, always return the vehicles computer back to the factory programming. Once you have the vehicle back from the dealership, reinstall the Speedometer Calibrator Programming as before. The Speedometer Calibrator can only be used on one (1) vehicle at a time, so if you sell your vehicle or want to use it on a friends vehicle, simply return your vehicle to the stock program and you may then use the programmer on another vehicle that is covered in the same part number.
The Speedometer Calibrator comes with a USB cable and a CD containing software to enable quick updates or upgrades over the internet. If your vehicle has a new calibration not available when your Speedometer Calibrator was manufactured, it is possible that you will see a Cal not found message on the Speedometer Calibrator screen. If this occurs, you can simply update your Speedometer Calibrator with the correct new calibration via the internet. Simply connect the Speedometer Calibrator (using the provided USB cord) to your computer and go to www.hypertech.com. Then click on the Support button to get update downloads. You can also get the update downloads using the supplied CD which in addition contains an installation video and a printable version of the instruction manual.
