Im converting to EFI on my series two and i have chance of an OFAC setup.....the more popular route seems to be the OFAB setup is there any reason for this or is it a case of theres more OFAB kits availible.

Is this a good conversion?surely its more efficent than mfi

Thanks

 

 

You can use Cossie 3-bar MAP sensors with the OFAB ECU - it will just need a chip or reprogramming. With OFAC you are stuck with the standard MAP, I'm not sure what the max. It can read is, probably 1bar boost, maybe 1.5?

 

Dont think i will be buying that setup then as im running around 20 psi...
thanks for reply
