no tried that as have a scanguage,i know the mass air flow sensor is shot so am replacing it,just its a wrx ppp running 270/270 when standard.
its since had a front mount
wrapped ported headers
decat full system etc
apexi induction
all this was done ages ago,and car runs fantastic!(you cant map the standard ecu with ppp)
was told i should do a ecu reset and allow it to sort itself(allthough its been fantastic anyway)that the ecu would re read it!
ive driven the car easily over the last year as clutch was slipping now and again.
just had a big act clutch fitted and having never reset the ecu before thought id give it a go.
