MoTeC Calibration 45
Data Logging & Road Testing
The calibration must be verified on the road, this is best done by logging the
air fuel ratio and other sensors and checking them using the MoTeC
INTERPRET Software.
Data Logging is also very useful for uncovering unexpected problems such as
an incorrect air temperature reading due to fuel vapour cooling the sensor or
excessive air temperature due to hot air entering the intake system.
Data logging may also be used to verify and fine tune the operation of the
various advanced functions such as traction control.
The light load and overrun calibration must also be completed on the road as
these areas cannot be adjusted on a dyno.
