TPS sensor must be calibrated on the first time the ECU is turned on
only, and should be recalibrated only when it has to be replaced or the
throttle opening on idle was changed. TPS calibrations are individual
by map file.
TPS signal voltage must go up, as the pedal is pressed, and must have
at least a 3V difference between the idle and WOT positions
15.2 Electronic throttle/pedal calibration
IMPORTANT:
Every time the pedal calibration is done the
throttle automatically calibrates its opening
limits. It is very important that during this
calibration the engine is turned off because the
throttle is fully opened and closed.
This calibration procedure is exactly the same as the mechanical throttle
calibration. The only difference is that the calibration screen shows
voltage value on both TPSs of the electronic pedal.
With this done, it is necessary to adjust idle speed control parameters
as guides chapter 19.2

15.3 Fuel/oil pressure sensors inputs
In this menu are the settings for fuel and pressure sensors. There is
a predefined configuration for PS-10A, PS10-B and VDO pressure
sensors, but any kind of analog sensor with 0-5V signal can be used.
This configuration is done through the PC and software FTManager.
In case there is a reading error between the FT500 / FT500LITE
screen and the real value of the sensor (comparing to an external
gauge), this compensation is easily done by adjusting the sensor
offset. It is possible to edit this compensation in mV or in pressure
offset. Just change the button on the top part of the screen between
“Input value” (mV adjust) and “Output value” (pressure offset). The
field “Read value” shows readings in real time..
Make sure your external gauge is correctly calibrated and that the
correct sensor is selected, as incorrect use of this function can cause
significant error in pressures reported.

Reading
The FT500/FT500LITE has fully customizable inputs, which allows to
read any 0-5V analog pressure sensor, since its pressure vs voltage
table is known. In this case, just select the custom option and fill the
interpoltation table through FTManager.
15.4 Intake air and engine temperature sensors
In this menu are the settings for intake air and engine temperature
sensors. There is a predefined configuration for GM and Fiat sensors.
In case there is a reading error between the FT500 /FT500LITE and
the real value of the sensor (comparing to an external gauge or to the
dashboard), this compensation is easily done by adjusting the sensor
offset. It is possible to edit this compensation in mV or in degrees.
Just change the button on the top part of the screen between “Input
value” (mV adjust) and “Output value” (temperature offset). The field
“Read value” shows readings in real time.
Make sure your external gauge or dashboard is correctly calibrated
and that the correct sensor is selected, as incorrect use of this option
can cause significant error in reported temperatures and possible
engine damage
