ecu's
 

can any one tell me the difference between the 2 fiesta rs turbo ecus,(i think one is called ofab?) is one better than other any help would be great thanks :top:

the ecu is on the passenger side behind the dash, it should have a sticker on the bottom saying ofab/ofac, i think it also says on the plug on the top end of it (you will need to remove the large rubber boot near the jack in the engine bay to remove the plug, x2 10mm nuts). also, the map sensor on the ofab is exactly the same as the standard saph cossy one, sort of triangular. the ofac one is more rectangular (like 10 silkcut size!) this was asked on www.fiestaturbo.com a few days a go. i posted a pic of the ofab map sensor on there (can't do pics on here :( ) :top:
