i dont know much about this tbh
the evo 7 uses a fan control unit so the ecu send info to that not the fan its self like the evo 2

hope im right in saying that :smile:

hi , i just checking my fan wiring .. now fan are working early on 90c off 88c
but different from the table ... i just adjust the table on 85c and off 80c
but how the table and the fan working so delay ? confused ......

it will not work, there are no duty cycles for evo 2, there is just high and low, to get duty cycles you need to install the fan control unit which runs on PWM.
