Several other screens and adjustments are available for diagnostics and fine tuning.

Throttle Position Sensor Voltage

TPS VOLT

This screen shows the current voltage on the pressure / throttle position sensor. This provides diagnostic information only.

   2.50V

 

Throttle Position Sensor Calibration Low Voltage

TPS LOW 

This screen shows the voltage on the pressure / throttle position sensor that represents the 0% throttle position.

   1.50V

Usually this value is automatically determined by the TPS calibration. If it needs to be fine tuned, it can be adjusted here. Press “select” to adjust, then use the “up” and “down” keys to increase or decrease the value. Press “select” again to exit.


 

Throttle Position Sensor Calibration High Voltage

TPS HIGH

This screen shows the voltage on the pressure / throttle position sensor that represents the 100% throttle position.

   4.50V

Usually this value is automatically determined by the TPS calibration. If it needs to be fine tuned, it can be adjusted here. Press “select” to adjust, then use the “up” and “down” keys to increase or decrease the value. Press “select” again to exit.


 

Speedometer Adjustment

SPD ADJ 

This adjustment provides the ability to fine tune the output that drives an electronic speedometer.


 

Speed Sensor Calibration

There are two menus that allow calibration of the vehicle speed sensor.  The default pulses per mile for both GM and Chrysler applications is 8000, but if the on screen speed reading needs to be adjusted, these menus can be used to compensate for final drive gear ratio and tire size differences.  

PPM CRSE

This menu adjusts the pulses per mile in a course fashion.  Each press of the up or down arrow changes the pulses per mile by 1000 counts.

PPM FINE

This menu adjusts the pulses per mile by one count at a time.


Measurement Units

UNITS   

The measurement units for the system can be set to US customary units or metric. Press “select” to adjust, then use the”up” or “down” key to select either

      US

or

  METRIC

Press “select” again to exit.


 

Factory Defaults

FAC DFLT

If necessary, all of the original settings from the factory can be restored using this screen.

Press “select” and then the “up” key to confirm.

The COMPUSHIFT Mini will reset and all previously-set parameters will be restored to their defaults.
