teach me oh bonneville obsessionists
since i got my aeroforce scan guage i have seen a lot of parameters that i dont really know what they mean.... i am putting a :?: next to the ones i would like a better definition of, and what to look for....
MPH: idle: 0 WOT: ???
:?: Knock Retard: idle: 0 WOT: 2.5-3 <--- exhaust mods should take care of this?

Your timing is low becuase of the KR. Once you get rid of the KR your timing should come back to 17-19*
IPW'* are fine-once you start getting in the 22 range you just maxed out your stockers.
The rest somebody else will have to help you on, as I am learing myself.

its 17-19 On my series II NA as well, and 24* on the 91 LE 3800....
Haro,
Have you thought about the PEM'* or Headers?

What exactly do you mean? The definitions of the terms/phases or what?
I'm confused, because it looks to me like you knew what they meant?
I'll be more than happy to help, if I new the question. :?

:?: Pulse Width MS: <-How long the injector is open for.
:?: Short Trim: <-Short term memory of sorts for the fuel. This ultimately changes the long term fuel trim.
:?: Long Trim: <- Long term fuel memory kinda. How much your computer is compensating for a lean condition (positive %) of rich condition (negative %)
02 voltage:<-- If its oscillating, thats good. If it stops at WOT thats good too. During normal driving it tells you nothing much really. But at WOT you want your 02'* to be at a certian # ( I can never remember that, 850 mV?)
Battery: <-Sopose to be around 13.7
:?: IAC Position: <-How far the idle air control valve is opening. This valve bypasses air around the TB plate allowing it into the engine. It allows the TB plate to be closed and still have the engine suck in air. There is a sweat spot for this too which I forget exactly. Basically if the value is too high you need to open the TB plate via idle screw. If the value is too low your TB plate may be open too much.
Engine Load: <- pretty much what determines what gear your in, how much fuel, spark advance, wether or not to turn the egr on etc.
Intake Temp: <-you know that one
Coolant Temp: idle: 138F WOT: 192
Trans Temp: idle: 102F WOT: 145F <-- in the summer, what is the maximum temp i am gonna wanna see? <---In the summer you'll probably see 180-190.
RPM: idle: 930 WOT: ~5500
:?: MAF LB/M: <- lb/min of air your TB is flowing
:?: MAF Frequency: [b]<-The frequency is calibrated to the flow rate above
Manifold PSI: <-Vac at idle (not sure how much on a */c) and whatever lbs. your runngin at WOT
Throttle Percent: idle: 0 WOT: 99
:?: Throttle Volts: idle: .33 WOT: 4.09 <-- shouldnt this be 4.75v, i need to do the TPS mod right <--Since your throttle percent is 99 you should be fine.
