5.0 Plug-in Specific Information
5.1 Fuel Model
The base ECU calibration is supplied in Speed Density mode. It is recommended to install an
Emtron 4Bar MAP sensor and wire it to a spare ANV Input in the Emtron expansion port.
The ECU may also be configured to run on MAF only or using a combination MAF and Speed
Density (MAP).
5.2 Inlet Air Temperature
ECU Pin 72 is assigned to the Inlet Air Temperature Sensor. The sensor is physically located
in the Mass Air Flow Meter. This is not ideal for the fuel model and it is recommended to
install an inlet air temperature sensor in the inlet manifold. This can be wired directly to pin
3 in the Emtron expansion port connector as shown in Table 3.0. Anv8 may then be
assigned in the inputs setup page in Emtune.
Some EVO models have an inlet air temperature sensor fitted however this is not accounted
for in the Emtron Plugin ECU. It is recommended to wire to the expansion port connector.
5.3 ECU Pin 40 Configuration
ECU Pin 40 configuration will depend on the model. A low current, low side driver is
connected to this pin controlled by Auxiliary Output 13.
EVO 8- Crank/Cam Sensor Ground
This is a ground pin for the Crank and Cam sensors and acts as an immobiliser function. Aux
13 needs to be switched ON to provide a ground and allow the engine to start.
EVO 4-7
–
CAT Light
This is the CAT light and requires a ground to switch the light on. Aux 13 can be used to
control this light.
