The Electric cooling fans can be controlled separately. Just a reminder – the system only controls a RELAY. DO NOT CONNECT DIRECTLY TO THE FAN – THE ECU COULD BE DAMAGED, AND DEFINITELY THE FAN WILL NOT WORK. The ECU provides a grounding signal for the control solenoid of the relay, which energizes the relay and allows the battery to supply voltage to the cooling fan.
Fan 1(2) ON Temp = Above this temperature, the electric cooling fan will be turned on.
Fan 1(2) OFF Temp = Below this temperature, the electric cooling fan will be turned off. Make sure to set this temperature below the Fan ON Temp.
Option Fan1(2) Enable = If you are not using an electric cooling fan that is controlled by the FiTech ECU, set this to Disabled. If you are controlling the electric cooling fan with the system, set it to Enabled. Leaving the fan in enabled mode, but without connecting a fan relay will result in a Fan Fault Code, and also some minor RPM fluctuations at idle when the ECU attempts to turn on the cooling fan.
