Is that good/bad/normal etc ?!?!?

ive read a few posts so my understanding is the Z4 ECU is a better one than standard or is an uprated one fitted by subaru, feel free to enlightenme guys.....

i wanna convert my wrx back to run on regular, so am looking to get a uk ECU so i can swap between regular when im skint, and the Z4 for optimax etc when im flush and want more umph.

does this sound feasable ?

can a uk 4 pin ecu, say, 7d be fitted to an import with no problems ?

cheers all.........

the z4 variation fitted to your wrx is standard for late 1994 1995 and 1996 wrx's ideally it functions very well with optimax only , but i have know a few people with z4's run on 95 regular unleaded for long periods with out any problems, except a slight loss in ooooomph, iirc am sure that the z4 map is almost identical to the prodrive map of the same era, so u dont need to change about unless u r planning serious mods.

cheers,the only reason i want a uk ecu is i dont want my lump going bang when i use regular on the z4 map, whatever it mite be.

safer to use a uk ecu isnt it ?
