Np, dude. I like infecting everyone with knowledge.
Get this, I live in BFE, Michigan. There are NO emission laws here whatsoever, but for some reason I still find the concepts envolved with emission control fascinating. I have to give props to one of my auto-tech profs for turning me on to that stuff.
Just to show you how much of an automotive engineering dweeb I am, I do "experiments" with my carbureted 4-bangers just to see how much mileage I can squeeze from them. I brought an '85 LX up to 32mpg, and my record-holder is my current '84 "winter-beater" 626 is running 35-36mpg, and climbing. It's nice getting 500+ miles to a tank when you're not burning the high-octane stuff in the summer through the 'Stang. I MISS DRIVING IT ALREADY!!!!
I guess it's an even tradeoff, really.
FYI, I'm working on intake temperature vs. mixture effects right now.
