yeah thats what i've found so far, but its kinda hard to mount an oscilloscope to your bike and ride around to figure out the details of the signal...
true its probably not worth doing money and effort wise but if i can do it for anything less than $150 i would do it, most of them are priced from 100- 150 and up. I probably have more free time than you
and i've done some basic microcontroller programming before , but really need to know the signal details first.
