I'm just starting to think about building an mjlj and rev limiter, but already thinking about how it could be done.
I already have a speed sensor on a front wheel (mountain bike speedo used while my speedo cable's been broken) that will produce road speed dependent pulses. I reckon that coupled with the tach out from the MJ and a simple PIC should let you work out if you're spinning up (in 1st gear at least) and cut spark. With rpm info from each wheel (or a front wheel and prop flange) full-on traction control should be trivial. Anyone laughing at me yet??
