Interesting problem

[alexander.foti]

I have a failry simple 125cc motorbike with electronic fuel injection.

I also have a cable actuated speedometer.

I know I can calculate fuel economy from tank fillups but it would be really nice to have on the go mpg readings.

If I fit a magnetic speed sensor, like those found on bycycle speedometers, how viable is the mpguino?

I really like the concept.

Thanks in advance for your help!

sounds pretty feasable to me

junk yards are full of cam position sensors they make great tach pickups. are your spokes stainless?

[alexander.foti]

I have cast magnesium wheels, no spokes here

Like this:

Would a cps sensor work on that type of wheel?

Also how would I go about obtaining/creating the mpguino as I have NO experience with this type of thing.

Thanks

Any ideas also where I could get this in kit form?

Thanks
