I plan on doing it. My only question is, we all know how unpredictible the fuel pressure readings are with that FPR. I'll set my idle pressure and 10 minutes later it'll be way different. So, if i get the AFC and tune my car, then my fuel pressure changes, will all of the settings on the AFC be void and useless or does it not matter?

Get a better FPR before messing with the S-AFC. Vortech S-FMU works nicely. Stable fuel pressure is at the heart of a good fuel system. Once you have that, then you can worry about adding a S-AFC.

That was pretty much how my fuel setup was, before I went with the Accel DFI. It worked pretty well for me. As long as you don't set the AFC fuel trimmings too much, for example, at .87-.89 volts, then I don't thing you'll have any problem. You should probably set the fuel system just a little rich to compensate for any possible FPR variations, until you have a known stable FPR.

I plan on getting one of those small convenient o2 voltage meters before i buy the AFC. I still have yet to determine much about how the S-FMU works,i've been too busy to read up about it. I just wonder why you can't adjust Hahn's FPR using that weird screw thing on the side of it.

Looked into it tonight, good idea Corbin. Most people are happy with the 2.72 disc am i right....i'll probably order one as soon as my Stafford loan comes in
