It is a japo ECU that is near exact same as UK PPP ecu settings. So needs be run on optimax. I think its set up for a TD04 turbo so see if this is wat you have!

I don't know the exact figures but the WRX is 260bhp as standard iirc as a result of the different map to the UK cars used in the Z4 ECU. Do a search on here. A lot of people use the Z4 for a cheap increase in poke.

It will increase the boost to 12.7spi from 11.47 psi and the fuel/ignition maps are slightly smoother then the standard UK. It will be safe to run on 97/98RON.
The prodrive map was based on the Z4 but ran a peak of 13.64psi with very little change elsewhere. Prodrive recommended this to be run on 97Ron also.

I ran a Z4 on a MY95 UK for ages, it does make a good difference and with a MBC you can push boost to the PPP level and a bit more, i ran 1 bar saftely with no knock on SUL97.
I was told it will never give the 260bhp standard as the WRX has different cams, and the figure is claimed using 100 ron fuel. I never got the car dyno'd but from the datalogs we were seeing airflow that should produce around the 270bhp mark, Decat, panel filter and 1 bar.

Fuel cut on the Z4 is about 15.9psi IIRC.

Many moons ago I ran a car with a Full decat, uprated panel filter, Z4 with 1bar and got 280 BHP
Same car without the raised boost gave 265 BHP
