Pressure measurements

The system offers a lot of different pressure channels, please see function de‐
scription input signal processing for details. For gradient and offset information
contact sensor manufacturer.
Example: Ambient Pressure
PAMB_OFF, PAMB_GRD
UPAMB_MIN, UPAMB_MAX
PAMB_DEF
FCPAMB
All other variables are named by the same rule, replace "pamb" by e.g. "poil" to
apply data for the oil pressure sensor.

Temperature measurements

The system offers a lot of different temperature channels, please see function de‐
scription input signal processing for details.
Example: Intake Air Temperature
UTINT_MIN, UTINT_MAX

Minimum and maximum accepted sen‐
sor voltage. When violated, an error is
set (E_pamb = 1).
Default value if an error occurred.
Filter constant. For ambient pressure
use 1 second, for other pressures
choose appropriate values, ~ 100 ‐ 200
milliseconds
Minimum and maximum accepted sen‐
sor voltage. When violated, an error is
set (E_tint = 1).
