I have a Subaru Impreza 2.0 GT AWD from 2000 and I would like to fit in my car (if I find one to buy) a Prodrive WR Sport ECU only. I already have a complete ScoobySport exhaust, turbo/intercooler and cooling Samco Sport hoses and I would like to know if I install (if I can I do not know) a Prodrive WR Sport ECU I can have some problems or if I have to make some upgrades in my car. The car work weel?? If I buy a second hand Prodrive WR Sport ECU I have to made something to reset it or I can fit it whitout doing anything??

Thank you whit regards.
