20.6 Cooling fans 1 and 2
The electric fan control in the engine cooling system is based on the temperature in which it is expected to be
activated and disabled. One can establish that the electric fan must be activated when the engine reaches 194
o
F and
turned off when it cools to 180
o
F.
This ECU can control up to two cooling fans on different
fans to be activated when A/C is turned on. As these fans may draw considerable load, a fuel compensation is also
available.
20.7 Air conditioning
To control air conditioning through FT500, first you have to setup an output to control the A/C relay. Then, setup
the input that will receive signal from the A/C button on the car dashboard. Check chapter 14.2 for more information.
20.8 Fuel pump
This output activates the fuel pump by grounding the relay that controls the pump. When switching the ignition
key, this output is activated for six seconds, and it turns itself off if the ECU does not receive any RPM signal. The relay
must be adequate to the current needed to power the fuel pump.
