TPS (Throttle position sensor)

Throttle position sensor is, next to the MAP sensor, the key sensor allowing to define the engine's
load in algorithm Alpha-N, to calculate the coefficient of enriching the mixture with the acceleration
and controlling engine idle. Calibration of this sensor is limited to the determination of 2 limit
positions of the boundary locations of acceleration pedal. Voltage from TPS can be checked in Log
/ Analog Inputs / TPS Voltage.

DESCRIPTION
When checked, internal MAP sensor is used
Offset used to precisely calibrate internal MAP sensor readings
Measurement range of external map sensor in kPa of absolute
pressure
Offset used to precisely calibrate external MAP sensor readings
Analog input used to read voltage from external MAP sensor
Offset used to precisely calibrate BARO sensor readings
When checked, activates MAP sensor signal digital filter
Power of MAP sensor digital filter. Higher filter power gives more
"smoothing" to the signal, but with higher filter power comes longer
signal delay from MAP sensor. Value set here is used only when
Digital filter mode is set to Mode 0.
Mode 0 is used to keep compatibility with software 1.066 and lower.
Modes 1 - 3 are used to select low-pass filter cutoff frequency. Cutoff
frequency decreases with mode number. When mode 1-3 is selected,
filter power can be set in MAP Filter power table
DESCRIPTION
TPS voltage for fully closed throttle
TPS voltage for fully opened throttle
TPS value assumed when TPS voltage is below TPS Min. Voltage
TPS value assumed when TPS voltage is aboveTPS Max.
Voltage.Can be used as a failsafe.
Time constant used to calculate TPS Rate (dTPS) value. It is used to
regulate TPS Rate sensitivity.
