I bet this isnt the 1st post asking but anyway,
Whats the difference? OFAB can run more boost std?
And what would be best to convert my S2 and how easy/hard?

The main difference is OFAC uses a digital map sensor (like inside an escort rs turbo ecu), which limits you to 1 bar of boost (or fractionally over-it with suitable calibration).. OFAB uses an analogue map sensor, which means you can use the likes of a cossie 3 bar and run more boost..

Some people do various hacks to OFAC to run more than 1 bar, none of which are particularly proper.

So ofab is the one to go for,
