Now see, this is why I like hangin out with you guys.
Look at all the cool stuff you can learn.
Now I not only need an AFR but an EGT as well now that I know
how to use em. All I need next is a flight engineer to watch em
all. Or maybe a data logger..that's the ticket!....I can get suspension
telemetry too
......please somebody stop me!
Great feedback, thanks

Subject: Re: [Fot] AFR vs EGT = brain damage
AFR and EGT in my mind are for different purposes. The EGT is a
quick check that I'm not going to send aluminum out the exhaust, and
when the car runs like crap it, along with my fuel pressure gauge,
give me something to help diagnose the problem.
Fuel pressure = 0 and EGT's go up and then drop means I forgot to put
gas in the fuel cell again. One EGT lower than the other - front
carb or rear carb problem. Good fuel pressure and egt's go to zero -
I just lost spark. Etc.
I've used the AFR on the dyno to get the carbs right across the
entire rev range. Made a ton of difference in power. Also killed
the new sensor over the course of the dyno session - it was a
standard single wire one from the Napa store.... Wasn't terribly expensive.
