Hi, I would like install one KOSO instrument in my ETZ 251. I have the electronic ignition from powerdynamo.com. The tachometer work with one sensor in front wheel, this is not difficult to install. I can install too, one temperature sensor in the Cylinder head. My problem is set up the RPM in my ETZ 251. I dont understand much about this so I would like somebody help me understand where and how can I install the RPM

I would try to get the signal from yellow wire between sensor and ignition coil with rpm wire set A. But i´m not sure, please wait for other answers.

Bad news: push At first you should find out internal ratio of the Coso instrument, if you did it, you should contact Powerdynamo GmbH directly and describe your problem to them.
