Fuel Pressure Regulator

Can you tell me more about what the S-AFC actually does. i know it regulates the A/F mixture but how?
Thanks
 
Hello

I didn't want to make a whole new topic so I ask in here.

As anyone used APEXi Fuel pressure regulator? One company offered Type B and C for me, but I can't find any info about these in the net.

Thank you in advance

The mummy is alive!

I have the intake freed up, the full exhaust has been done. Next plan is the P&P and I talked to the guy who dynod my car, he said the CO is coming close to the normal, which means A/F ratio is coming to stoich. And when I do the P&P , I just don't want to take the risk running it lean. So just in case I would need the FPR, when I have to add some fuel.

I hope I have understood it right :)

What are you looking at doing with FPR?
 
Once you have done the other stuff, I would see what you A/F ratios are before adding a FPR...

It might not be needed.
