I see the gauge's formula for analog in is a/f=2*volts+10 and the plx gauges output formula is a/f=2.5volts+8.75.
I calculated it out and it looks like the plx will give off 1.5 volts for 12.5 and .9 volts for 11.
So does that mean i should set my a/f cutoff at 11.8(.9v) and 13.0(1.5v) on the gauge and then make the delay 3/10s of a sec.
Or should I set it up differently?
Give yourself a bigger window than that for the rich end of the spectrum. Honestly, everyone's car will be set up different so there won't be any 1 program that fits everyone's needs. For starters you can try that, but I think you'll have better results opening the rich end up a little.
