Ecu internal Counter and MFI relais (fan)
Ecu internal Counter and MFI relais (fan)
Form the evo 8 manual:
The main fan control relais is wired to the MFI relais.
i think its just the delay for the mfi relais which is set to 5 min when coolant is above 110 degC.
Under normal temps it is active for some seconds, then you hear a clicking sound when it switches off.
After reflashing its emmediately clicking.
Does anyboy came accros the coolant temp, or the counter for the mfi relais?
anything that could help?

NOTE: If the engine coolant temperature reaches 110°C (230°F) or higher, the cooling fan control runs the
cooling fan for up to 5 minutes even after the ignition switch is turned to the "LOCK" (OFF) position [the fan
stops its rotation when the engine coolant temperature decreases to 110°C (230°F) or lower.]

In the wiring diagram there is no sign off a non-ecu circuit.
MFI relay is switched on by the ecu itself. And the MFI relay is connected straight to the battery. The ingition wire is just a trigger to wake up the ecu.
