I heard OFAC was better, but couldn't tell u why myself.

OFAC is the later management. Uses a digital MAP sensor, limited to 2bar (-1 & +1). Using the earlier management, OFAB, you can use the cosworth 3 bar map sensor.

i built the car i aint payin sum1 else to change a loom and ecu and MAP

and i have spare engines and plenty of time

not that changin it to ofab is gonna blow it up neways

Yeah, OFAB will allow you to run more boost. With the correct chip/map and MAP sensor.

Only worth it if your going to actually run that boost though, rumour has it that OFAC runs the car slightly better, using the digital sensor, more mpg too !

Not too difficult to change over either,

ow now i dont know what to do again

i have a spare engine that will eventually be put in my mk1 xr2 (no holdin of breath tho) and my erst will go back to ke jet and the managment will go into the mk1

just wanted to free up some cash offeither managment setup and keep the best for myself

i think ill have to find out about the ofab chip to be sure (live map 1)

cheers for the input tho mate

Will an Escort cossie MAP sensor work with the OFAC management??

scort

Why would you want to?

Avinitlarge

Because I need a MAP sensor and cant get hold of an OFAC one but can get a cossie one

scort

Ahhhh, I see.

One way to find out......
