Hello Guys!

I tried on the scooter today, it works
Here is a video...but there is a problem, that i sad yesterday...somehow it recieves more than one pulse per revolution, and displays me 10.000 rpm where it is actually 5-6000...so i have to fix it somehow...maybe it can be the solution to make the reciever less sensible, but how?
I don't know wat kind of power youre using, but I think you need some more capacitors and building your CDI into a metalcase.
Its possible spikes from the coil disturb the hallsensor or the timerboard.

But a big thank you for this fantastic project!!!
Thank you !!
You show use the first CDI on a real working engine, GREAT !!!!

BTW, is't a 2 or a 4 stroke engine ?
If it's a 4 stroke, the table must be rotated, start at low degrees and in high rpm high degrees.
The table a see on your laptop must be use for a 2 stroke engine.
