Hello Guys, Paul here from Germany.

I am doing a little project and I need your help.

I consider to tune the fuel maps by myself. Therefore I need a good RPM signal to feed into my arduino.

Some guys here had there bike on a dyno. Probably one of you has still in mind where the tuning dude picked up the rpm signal.

The circuit diagramm didnt supply any good information.

Maybe someone has a interesting idea.

Greetings, Paul

Dyno guys usually just use an induction pickup at a coil
I think the Ecu is conditioning the RPM signal from the coils..
There must be a cable on the harness, where I can pick it up.

I will have a Look at the coil cables with a osci.

Tanks for your reply
