Am converting to EFI and wondered what the difference between these two E.C.U systems are and which one is the best to use.

 

OFAB is the earlier type with marelli MAP sensor

OFAC is the later type with a Ford own MAP.

OFAB is rumoured to be the better, plus you can easily upgrade to a 3 bar cossie MAP sensor.

 

New you would come up TRUMPS.

 

yep ofab is the better one why they ever went to ofac to beoned me

 

double post

 

what is better to use out of OFAB and Cosworth management?

 

what level of cosworth mangement?

im just curious as some people use Cossie management and some use Fiesta Turbo management. just wondered if there were any particular advantages for one over the other...
