hi i have been offered a mapped prova ecu from 95 classic impreza turbo, i was wondering if it will fit straight into my 95 impreza wagon turbo with out alot of messin around ?
thanks

 

from what they say id pass on a prova ecu bud. they are supposed to have a very aggresive map with very advanced timing etc to suit jap fuel. you would have to be running the same mods as it was mapped for and also would need to add octane booster to your fuel i think. better option is apexi and commander or esl live mapping.
