How to set up a/f shutoff? Ok I ran through my setup to make sure all my spray stuff is working correctly.
Right now i have torquer v3, full boltons, racetronix, green tops, HSW wet plate kit, tr-6s.
I just put a warmer in and have all the safety stuff.
I am running 12.8 a/f and 23* timing n/a.
I have the recommended jets in for the 75 shot. The timing on the 75 shot is 20* and whatever fuel it adds itself on top of the 12.8.
What should I aim my a/f to be and how should i set up my a/f shutoff? I believe i can set rich cutoff, lean cutoff, and time to cutoff in tenths of a second.
Whats the best rpm to start the spray? I think i have it set for 3500 right now.
Im gonna learn to read plugs to fine tune things.

OK so I have a p series nitrous gauge with the a/f shutoff and a plx wideband.
I have a harris speed works wet plate kit up to 150 shot.
Ive been told my a/f should be between 11 and 12.5.
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?
