i have a my95 wrx wagon import which i recently changed the ecu to a z4.
does anyone know if the z4 ecu was off a uk car or imports as well. i ask this
in regard to whether the ecu is mapped for uk fuel.
also fully decatted it last week as well as rerouting the air duct through the inner wing to the front to take in cooler air. does anyone know what bhp the ecu is mapped for and approx how much i should be getting now. any ideas
or help is much appreciated. thanks

 

hi, I think the Z4 ecu is only on the import models, so you will will need to run on optimax and booster!
should be good for about 250/260 BHP.
