Hello
Firstly about the car. Its an Evo Viii with an ECU swap, there is an Ecumaster Black Emu and tuned up to 390-400Hp, it has racing sparkplugs in the engine, and racing resistors on them, and new fuel pump. I have to tell that the IACV (idle air control valve) is bad right now, on the way the new one, but i think its not related to the case.
The problem is periodic, thats why i dont know where i need to search it.
So I turned the key to Ignition:ON (not starting the car), and the A/C Condenser fan (the bigger black one on the left side, not the engine cooler fan) comes ON and cooling crazyly.
Inside the car it has a JDM module for AC, the AC button is turned max to left side and OFF. So on this settings the fan need to be OFF too, but its ON and spinning as hell. This problem is present in 70%. In the other 30% its working normally how its need, the A/C fan is off ,if i push the button inside the car it cames ON and cooling.
I thought about that maybe the tune of the new ECU kidding me, but if the tune is bad, its always bad and its not working fine in 30% of time.(in my mind)
Where i need to searching the problem?
