How many pulses per revolution does the speed sensor get from the output shaft?

Well, when another guy was setting up a cruise control, which has a VSS signal, he set the cruise control to something like 38,000 pulses per mile, or there-abouts, to come off of the bikes VSS (speed sensor), and said that worked for him.

Thanks JDC.

But after thinking about it, I believe it's 4. Because of the 4 lobes on the front sprocket nut. So, for each revolution of the output shaft the speed sensor see's 4 pulses.?

Ok. But isn't the speed sensor rotation rated for pulses per kilometer/mile (PPK or PPM)? For the cruise control gadgets that seems to be how they are set up at any rate.

What type of mischief are you getting into?

I'm setting up the speed calculator in my new Motty AFR Tuner software

On my 1st run it recorded a top speed of 146, should have been 166.

The "speed scale calculator" asks for wheel circumference, # of front & rear sprocket teeth, and speed sensor(gearbox output shaft) pulses per revolution. You input this info and it returns a "speed scaling factor". I'm assuming with this info and engine rpm they calculate speed.

Ah... very nice.

I saw you Motty post. I had considered one. Maybe it is better than Bazzaz...

I put a post on your bikeland Motty info.

I'm interested in hearing how it works out.
