The GaugePAC, Hypertech's Performance Automotive Computer, allows you to perform runs just like you're at the drag strip, dyno test your engine to compare gains from aftermarket modifications, monitor virtually every engine and transmission function as a digital or analog gauge, diagnose problems, and clear "check engine" lights. The Drag Strip program allows you to measure your vehicle's performance and produces an exact duplication of a drag strip time slip, with reaction times, 60ft, 330ft, 1/8 mile, 1000ft, and ¼ mile speeds and ETs. The Dynamometer programs calculates both the horsepower and torque verses RPM at the engine as well as horsepower verses road speed at the driving wheels. Gauges function will display all sensors available for your vehicle. Touch any sensor from the vehicle list to be displayed. Depending on vehicle sensor configuration, up to 14 sensor inputs may be selected and displayed. The Diagnostics function allows you to read and clear Diagnostic Trouble Codes (DTCs). In addition to Code number information a short description of what the codes mean will be displayed. The Vehicle/Owner Information feature gives the owner the ability to review or configure various overall setting for the GaugePAC such as display settings, volume, basic vehicle information, etc.
