Yes. I really do want to use existing signals. They're easy to get to. It's just a matter of calibrating them.

PW at idle seems to be about 400uS.

After some experimenting, VSS = 8400 is close. Haven't gotten to uS/Gal yet.

I'm wrestling with what looks like noise. When the car is stopped with engine off, speed registers about 14-15 mph and mpg keeps ticking slowly. I'm reworking my connections to the car. Alligator clips now.

My MPGuino is on a breadboard and seems to be working correctly.
