Install the wiring for the thermofan to one of the Digital/PWM outputs as described in figure
16.6. Be sure that the relay contacts are rated higher than the current drawn by the thermofan.
Run the E6K programming software and go to the Options page. Select the Thermofan
function on the appropriate output and set the two temperatures as required.
Switch On Temperature
The temperature the engine coolant must exceed to switch the fan on.
Switch Off Temperature
The temperature the engine coolant must drop below before the fan will be switched
off. This parameter should be at least 5° lower than the Switch On temperature to
prevent the fan from switching in and out repeatedly.

16.7 Electric Intercooler Fan Control (IF)
This function can be used to switch on an electric fan on the intercooler when the inlet air
temperature exceeds a certain value. The fan will stay on until the temperature drops below a
second value.
NB: The electric fan cannot be driven directly by the ECU. A relay must be used to switch the
high currents drawn by the fan.
To use this function, you must have the following:
An electric fan, fused and relay switched;
E6K programming software and cable.
Install the wiring for the intercooler fan to one of the Digital/PWM outputs. This should be
done as described in figure 16.7 for the intercooler fan. Be sure that the relay contacts are
rated higher than the current drawn by the fan.
Run the E6K programming software and go to the Options page. Select the Intercooler Fan
function on the appropriate output and set the two temperatures as required.
