01 STI PPP ECU on WRX 03
Will this work ok?
I take it the engine is basicaly the same - just different pistons etc?
The only thing I can think of is the rev limit might be higher on the STI so pistons might not stand up?

Ohh dear, do not try this on your WRX.
Firstly the ECU wont work at all unless you have your engine immobiliser on the ECU reprogrammed to match your keys.
The STI is a totally different beast to the WRX, injectors, Turbo and Fuel pump are all different and the engine is NOT the same.
The major difference as already pointed out is the VVT fitted to the STI unit.
Dont presume that you will suddenly get 265 BHP as you wont, stick with the original ECU and have it Ecuteked with a full de-cat and expect 280-295 BHP.
