Hi guys.
I have a 93 WRX import with the following mods- Induction kit (pipercross), 3" decated exhaust, Megan headers, MBC, Baily dump valve. Do I need to do anything with the ECU yet? Who do I need to see? And how much? Cheers for any advice. Mark.

 

To get the best out your mods a remap is advisable but you can run your standard ecu as long as you use optimax and booster. to get a rempa you would need to get a new ecu e.g apexi power fc from andy f.

 

Cheers Banny. Due to cost I think I will see how I get on for now. I just use Optimax without booster at the moment. I will do an ECU reset and get some octane booster. Cheers. Mark.
