Hello! I have the standard SparkSwitch, operating Moki 250 5-cylinder radial engine. Perfect. Now, I would like to replace it by the PRO version, predominantly for RPM measurement. Is it possible? Does it work with the radial engines? Shall I use the RPM pickup cable? When to place it? Around one high voltage cable going to the spark plug? Actually, there are 5 such cables.
Please, let me know.
