Speedometer solutions got back to me 16 pulses/rev~16000 pulses/mi
Now it's time to figure out a few bits and pieces of math (for gear calculator). I need to know MPH/1000 RPM for each gear. I'm going to hit up google, but if anyone has this knowledge off hand it would be much appreciated.
EDIT: Well, guess what I just did
1st Gear: 5 mph/1000 RPM
2nd Gear: 9 mph/1000 RPM
3rd Gear: 13 mph/1000 RPM
4th Gear: 18 mph/1000 RPM
5th Gear: 26 mph/1000 RPM
As for 6th Gear... that I put at 0 mph/1000 RPM I may put it at 56 mph/1000 RPM so that it never gets selected--though I'm not sure which way I should go.
