4.2.1 Pressure Sensors
The label PRESSURES contains parameters to calibrate oil pressure POIL, ambient pressure
PAMB, crank pressure PCRANK and fuel pressure PFUEL. All pressures are calculated in the
same way. Example: Ambient pressure PAMB
PAMB_OFF; PAMB_GRD
Sensor offset and gradient. Consult the sensor manufacturer for details.
PAMB_UMX; PAMB_UMN
Maximum and minimum accepted sensor voltage. Set to approx. 250 mV / 4750 mV. If vi-
olated, an error is set (pamb_e = 1).
PAMB_DEF
Default value. If a sensor error is set, the output is switched to this default value.
PAMB_FIL
Filter constant. Use modest values, ~ 10 - 40 milliseconds.
All other parameters are named by the same rule. Replace PAMB by e.g. POIL to apply
data for the oil pressure sensor.
4.2.2 Temperature Sensors
All temperatures are calculated in the same way. The label “Temperature” contains para-
meters to calibrate oil pressure TOIL, intake air temperature TAIR, engine temperature
TMOT, fuel temperature TFUEL, etc. Example: Intake air temperature TAIR.
TAIR_UMX; TAIR_UMN
Maximum and minimum accepted sensor voltage. Set to approx. 200 mV / 4800 mV. If vi-
olated, an error is set (tair_e = 1).
TAIR_LIN
Sensor characteristic. Consult the sensor manufacturer.
TMOT_LIN
Ask the manufacturer for the linearization curve of the motor temperature sensor or
measure the electrical resistance by the temperature and calculate the characteristic.
TMOT_DEF
Replacement value in case of error, should be in the normal temperature range of the en-
gine (for example between 75 °C and 90 °C).
TFUEL_x ; TOIL_x ; TEX_x ; TEX2_x ; TAIR_x
If used: name as described in TMOT.
