Hi Jon-Magne,

I don't have test the cdi on a real engine, but on a real enginetester.
The cdi works great.....if you reverse the timetable, like I did.
I have to speedup the freq of the coil, 140 Hz was to slow to run high rpm.(~140 Hz =60x140=8400rpm)
I dubble the freq so the engine can run now ~17,000 rpm........I like 20,000 rpm, need more to test.
BUT.....the coil/ocsillator will not work with this freq.
I'll try to replace the coil to a real transformer 2x 3Volt - 220 Volt with a flipflop.
Something like this but NOT with this the components !!
