I made a tachometer input module in order to use my datalogger without the Ignitech controller.
It connects to the coil primary and the output is a 5V square wave.
On my desk, I ran a +/- 7.5V signal in (blue) and got a 0-5V signal out (yellow).
This, coupled with GPS, is enough to provide a gear indicator for stock bikes.
I'm also working on adding an ADC module to read the system voltage.
System voltage is also provided by the Ignitech, but this allows system voltage readings on stock bikes.
If there's any interest, I can set up a module to read a MAP sensor that is connected to either carb vacuum port, to capture engine load.
