both.
The throttle actuator angle will start to increase
(1 degree every 2 seconds). When the
calibration process is complete, a new offset is
created, and the angle on the display shows
zero again.
The calibration process takes approximately 30
to 60 seconds to complete.
Note:
Do not touch anything during the
calibration process, as this will cancel the
process, requiring you to restart the procedure.
Note:
During calibration, the engine speed
(rpm) should remain constant. Only at the end of
the calibration process you may hear the engine
speed slightly increase. If the engine speed
increases continuously, there may be an issue,
and the engine speed is not communicating with
the TEC controller.
