Hi people, decided i was gonna find out what ECU i have today and looked under the passenger footwell thingy to find out, and it seems i have an OFAB ECU.
So whats the difference between this and the OFAC one?
Think this has been asked before but i cant find the topic :rolleyes:

Later

OFAC is the later version of the ECU used in the FRST and requires a different MAP sensor, as Joris said. OFAC is a better setup than OFAB. However, OFAB allows you to run a 2 or 3 bar MAP sensor (from a Cossie) which is required for most big power Ze-VH and Zetec 16V turbo conversions!
