could anyone tell me what would i gain by fitting a z4 ecu to a my93.

bhp?
boost?

the car has still got a cat fitted but it does have a pipercross induction kit and a dump valve that is it

rated at 260ps not 240ps boost is slightly raised but held longer before dropping off at higher revs.

Did mine and it was a lot smoother through the gears.

WRX/STi Saloon ECU's 2C, U8, W6, W9 - As above, 11.47psi held to redline. Fuel-cut 14.57psi
WRX (1995/96) ECU Z4 - 12.71psi, dropping to 11.78psi @ 6600rpm. Fuel-cut 15.65psi.

6K ecu is allegedly the best straight swap ecu but when I did it I kept on getting a boost problem

yeah i made the upgarde. it aint gonna be jaw dropping but there is a noticable difference. car will drive smoother and come onto boost better.

cheers for the offer but the only reason why i ended up with this z4 is coz i won an ecu on ebay which had the esl daughter board in it but when i received the ecu the esl was missing but the ecu he sent me was a z4 so thats what is in my car at the mo ive had an apexi i 1 of my cars before plus ive had the esl before and i would say the esl is far better
