If needed, you can manually adjust TPS values by choosing “Adjust Idle” or
“Adjust WOT” in the TPS setup menu. Once the TPS calibration procedure is
completed, the values are permanently stored in the controller and will be active
for every tune written. TPS values displayed within individual tunes are then
irrelevant. If you require TPS customization for individual tunes or are using a
negative slope TPS, then the TPS values stored in the controller can be reset by
choosing “Reset TPS” from the TPS setup menu. Our provided tuning software,
Shiftware, can then be used to calibrate TPS values for specific tunes.
Possible TPS Calibration Errors:
Pedal Not Pressed / Acc Pedal Not Held
The throttle wasn’t pushed or held at maximum long enough for the test to
complete. Accelerator pedal must be held for 3 seconds and voltage must not
drop more than 0.168V below the maximum recorded value.
Pedal Not Released
The throttle wasn’t released within 5 seconds. The voltage must drop at least
0.96V below the maximum measured WOT value.
TPS V. Not Stable
The idle throttle position has changed values too drastically over the course of
the calibration. The idle voltage is more than 0.6V greater than the lowest
recorded value.
Error: TPS V. Low
The voltage is below the minimum allowed 0.2V during any of the tests.
M. Busy, Try Again
EEPROM is busy, so the TPS settings couldn’t be written to it.
