Gauges
Aside from dual Aeroforce Interceptors and a vacuum/boost gauge, is there anything else I should be monitoring with a gauge that the Interceptors don’t cover?
What gauge combinations do you use?

i dont know what the inteceptors cover but...
fuel press. - you need
pyrometer - will help you know when goin lean or rich if you dont want to spend $$$ on a wideband
Air fuel ratio - wideband or dont bother (mostly needed if tuning yourself)
trans temp - might be in cluster (depends) or i think its covered with interceptor

Thanks!
I have the trans temp on the gauge cluster already so I won't have to spend any $$$ on that. I was just trying to figure out what else I needed and where the heck to put them.
Not much room in the SS for extra gauges!

You can set the Intercepter up to read analog inputs from a wideband and a 0-5 volt fuel pressure sender. I have it working with my Tech Edge WB now and I think Auto Meter makes a sending unit that's 0-5 volt, but it's not to cheep, around a $100 I think.

How does that work? Dose it use the led lights or can you actualy see a number from it?

Analog 1. This selection allows the user to enter a conversion for this 0-5v
input, which uses the right pin of the three pin connector. To read raw volts,
enter “1” for slope, and “0” for intercept. This is the default setting as well.
For example, say you want to input the analog output of a wide band O2
sensor kit. You know from the kit’s documentation that the output is scaled
such that 0v=10 A/F ratio, and 5v = 20 A/F ratio. The conversion would then
be a slope of 2, with an intercept of 10. In other words, voltage multiplied by
2 plus 10 would equal A/F ratio. In this example, a voltage of 5 would result
in 5*2+10 equals 20 A/F ratio. Another common use for these analog inputs
are for MAP sensors. The GM 3 bar MAP is a common sensor used to
measure high levels of boost. The conversion for this sensor would be V*9-
14.8, or a slope of 9, intercept of -14.8. The intercept can be tweaked if the
sensor does not read “0” with the key on, engine off. Our personal 3 bar MAP
had a slight zero offset that we adjusted by changing the intercept value.
These inputs use a 10 bit A/D device, and are highly accurate to .01 volts.
You will only see a resolution of 0.1 volt displayed, but the calculations are
based on the full 10 bit conversion and are not rounded off for higher
accuracy.
