I/P Manifold
Manifold pressure input select. Enter for more pre-defined sensors.
Default=Internal
USER DEFINED=Define internal or external (On some models only), span and
offsets.
I/P TPS
Input Throttle position sensor
Span & offset can be configured manually, but calibration should normally be done
as follow;
1. Ignition switch on, engine stopped.
2. Disconnect throttle position electrical connector for at least 20 seconds.
3. Reconnect throttle position electrical connector.
4. Ensure that throttle is closed for at least 5 seconds.
5. Fully open the throttle for at least 5 seconds.
New limits of throttle travel will have been learnt and stored in the ECU during the
above procedure. Additional ECU functions ensure that throttle stops and sensor
wear are compensated for over the life of the engine. The above procedure need
only be repeated if the butterfly / sensor assembly is serviced or replaced.
I/P Air Temp
Input air temperature sensor.
Options;
Autronic standard(Pre defined lookup)
NTC(Pre defined lookup)
Linearization 1..4(Uses linearization tables 1..4).
Linear(Custom span and offset for linear sensor).
I/P Coolant
Input air temperature sensor.
Options;
Autronic standard(Pre defined lookup)
NTC(Pre defined lookup)
Linearization 1..4(Uses linearization tables 1..4).
Linear(Custom span and offset for linear sensor).
I/P Batt
Battery voltage.
Linear is only option.
NOTE, May be trimmed to read correct volts.
I/P A/F Ratio
Input air fuel ratio sensor.
Select the analog channel that’s A/F sensor is connected too.
For A/F control, must be in air fuel ratio units only.
This is a general purpose input so can be linearized to any scale.
I/P Spare A/F
Spare input air fuel ratio sensor.
Select the analog channel that the A/F sensor is connected too.
