hello i no there is a difference in map sensors between ofac and ofab can u put a 3 bar straight on ofab.
what size map sensor are they 2 bar 2.5 bar
just need to no if u could run more boost then the other

thanks

 

You can only run 1bar of boost on ofac ofab you can run more

 

OFAB is a weber map sensor, so you can swap for a 3 bar (absolute) and run 2 bar positive pressure. OFAC is the ford type map sensor, and you can run 1 bar positive, but apparently this is a software issue and can be worked around to enable you to run +1.5bar. Speak to Stu@MSD as he'll be able to give you better answers than me

 

As Rab says the OFAC issue is a software not a hardware one.
