Orion VPM (Vehicle Personality Module) 1994-1998 Navistar

The Orion VPM, Orion Lite, and Orion Reflash System all use the same hardware, but have different Software and different functionality. If you have questions about which setup is right for you, please read below. Feel free to send any questions to support@phptune.com The Orion VPM (Vehicle Personality Module) allows you to adjust the Optional Parameters, read DTCs, and view live data off the "3-Box" 1994-1998 Navistar-equipped International vehicles.  Optional Parameters vary per vehicle, but the most common Optional Parameters adjusted are governors and speedometer corrections.  Due to the PCM setup of the "3-Box" systems, the Orion VPM cannot adjust horsepower levels. For additional horsepower, these vehicles require a Hydra Chip. The Hydra Chip can be purchased HERE
