Problems with radiator fans (Want change values with ecuflash)
Hellos guys, I have a problem.
My car had overheating problems a couple of weeks ago. It turns out that the radiator was bad and had to change the radiator and thermostat. My car is a JDM Evo 4 and buy a new thermostat for Evo 8 (thinking they were equal). When I compared the evo 4 thermostat active at 76.5 ° C and the Evo 8 is 82 ° C. Now radiator fans of my car when activated is never turned off.
I think this problem is because the temperature is above the original temperature of the car (76.5 ° C), so the fans never turn off. then, could be arranged by changing the values of temperature in the map of the car with ecuflash?
thanx!

Man I had exactly the same problem on my evo VI, You have a bad ECU swap, please check this link: http://www.evoscan.com/manuals/Evo45...20Diagrams.zip

Mauricio yo soy de Costa Rica tengo un Evo VI, mi problema era que con el ROM RalliArt de Evo 8 JDM se me encendían los abanicos a baja temperatura y luego siempre pasaban encendidos, luego pase al ROM tephra V7 y tuve miles de problemas, al final me dí cuenta que me habían montado mal la ECU del evo 8 ahora los abanicos prenden a 88ºc que es lo normal y cuando bajan a 82ºc exactamente se apagan, al final pude dejar bien puesta la ECU y pude poner a punto el ROM tephra por que a nuestros evos nos prenden muchos codigos que no tenemos como el Rear O2, si quieres te paso el ROM tephra para que pongas a punto tu evo y tengas mas opciones que con una ROM normal, tengo un Tephra con los mapas de combustible y tiempo del ROM ralliart del Evo 8 JDM si te interesa. Saludos.

Mira, la ecu esta bien montada ya que este sería mi 3er tune con mi evo. Ahora que ya lo desarrolle y monte un FP black, esta listo para el tune, creo que con la ecu todo esta bien.
But, i want to know what can I do with my problem?? i only change thermostat and i think that is the problem. I want to know how can I move the scale in ecuflash of the temp engine!

check the ecu coolant temp sensor in stat housing isnt disconnected or faulty (2 wire one).
fan shouldnt run till nearly 100c
what eng is in there as evo8 thermostat housing is completely different to evo4 and thermostat is bigger so physically wont fit
