Well that makes a lot of sense. I still dont understand how the very first pop is gona bee retarded as its takes at least two times through the sensor to get a speed. mine you can put it just before the sensor and flip it through and it will pop off and run. I guess its probably not retarded at that point till it hits the second time through the sensor.
so if your just pulling it through slowly by hand to see where it sparks then it sparks at full advance right?
Naw its smarter than that. It can tell the RPM on the first turn. It measures the dwell time of the magnet under the sensor and compaires it to 4mhz clock. So the size of the magnet is important. Its calabrated to work with andyhing smaller than 1/4" inch dia.
