Hi !
does anyone kwn... who much power increase would a ralliart ecu
give me .. with a filter and exhaust mod on a stock evo 7 ..thanks

 

I think Ralliart ECU alone can give you 15-20 WHP a filter can give you 5-10HP and a cat-back 8-17HP.
I'm going to buy all performance parts from Ralliart but after a lot of search here I can't find detailed information about the function from Ralliart ECU. The only thing I know is that this ECU modify the air/fuel ration and the waste gate operation, But I don't know if this ECU was made to use together with another Ralliart parts. Example: I suspect that this ECU modify the fan temperature operation to a lower temp, so it would be good to put a lower temp thermostat and radiator hose etc...
I don't know why Ralliart Japan don't give me a tech support!
