Some time soon i'm going to be looking to fit a mappable ECU to my JDM V3 STi. Not to run loads of power but to tweak it a little and so it runs safe on 98-99 ron fuel.

I spotted this ECU listed in the STi group N catalogue but can't find any info on it.

Can anyone shed some light on it? I doubt its mappable but if it would be more or less plug and play i'd certainly be up for one.

Its the one highlighted and is for a V3/V4.
