The SAFC I have has a high and low throttle setting, and you set the curves
per throttle percentage, say, your low is set at 0 and high is at 60% and
your curve is -10% at 3000RPMs, low throttle, and +30% at high throttle.
You happen to be at 30% throttle, its correction factor will be +10%, it is
not a set % per RPM or throttle, it will caculate the % needed as per your
tuning curves... not a sudden change...

I have it on the neon to just play around w/ it while the truck is gettin
worked on.... the video is shakey, but if you look at the bottom reading,
that is the correction %...
I understand what you are saying, but I think w/ the SAFC you'll get it
pretty darn close... 8 points of adjustment, from 1000PMS+ (under 1000 will
give you correction for what the 1000 is set at)
I mainly got it for using bigger injectors and a big cam.... (I'm sure you
know the darn MAP sensors suck when its time for a cam and idleing)
