Thanks for that but I'm going 100% custom on this one ;)
I have found a few that say contact us for different wheel sizes. I am happy to change a speedo cable but I am not 100% when it comes to replacing the whole unit. I may have a look in the summer and see if I can get the speeds checked for accuracy.Quote:

I would immagine that these universal speedos will have some way to change the wheel size as it would be uneconimacal to have a seperate model for each wheel size, it would probably be some sort of dip switch or potentiometer.
I bet that these are kind of hard to install as a lot of custom wiring will have to be done.
Well it's taken a long time because I'm lazy and stuff but my project is basically done, all that's left to do is fit it! I have ironed out 99% of the bugs in the software and it does appear that this thing is going to be pretty accurate when I actually stick it on my bike.
Wires everywhere :O

I have added a clock to it which should be handy

A distance and trip meter with a 0.05 mile resolution.

Top speed and 0-60 times which are kind of the main parts of this project

A basic fuel reading, the ammount in litres is based on the assumption that my tank holds 14 litres when the reading reads 100% but this will probably need a lot of tweaking to get right. The reading only updates when it is stable to within +/- 5% for 2 seconds which prevents the level from going all over the place while braking and accelerating. I plan to add some way to calculate MPG at some point.

...and a dedicated 0-60 mode which shows the best and last 0-60 times

Easy Tiger ... 0-60 mph in 98.99 secs that one quick bike must be a ducati, no all jokes aside
good job well done spencer keep up the post
Thanks prince ;)Quote:

The good thing about this system is it's universal and could be fitted to anything with a wheel (the RPM reading requires a crank position sensor to tap in to) so prehaps I could have a few of these made as an external unit to mount on the handle bars of a bike or on the dashboard of a car. I have seen some universal dashboards like this before but I don't think they recorded 0-60 times.
