Thread: Motorcycle data logging??

I'm looking to build a data logger for my motorcycle taking feeds from:

the speed sensor
the throttle position sensor
the tachometer

I have a basic understanding of electronic circuits and programming PIC controllers, so could probably put something together that will accept the signals from these sensors. But I have no idea how to go about storing the information I get from these sensors onto an onboard flash chip, and then how to get that information onto my computer (USB interface of some kind?).

Once I have the info on a computer I am able to write a program to interpret and graph it so it's just the middle bit that's the problem (I hope)

Any pointers or direction to books/websites that might help would be most welcome!

There are products on the market (such as Motec) that produce these types of systems - in the £1000's to buy and predominantly for fuel injected motors.

Then there is a Bazzaz system which uses the sensors I have mentioned to create a form of traction control based on rate of acceleration - again for fuel injected systems and around about a grand to buy.

I'm looking at playing with a project that does something similar to the bazzaz system but in a more generic manner, but with a carburettor system - and hopefully for much less than £1000.

I have the ability to program the PIC and write the software, and while I could work out the electronic circuit over time through reading and browsing, I thought I'd try here for a few short cuts into the flash circuit and computer interface

Here is a data logger for the tracks.
