Been working on a Arduino TCI project last couple of years. Got it mostly working. Still a few issues, but 95% of the way there. Here is a shaky video of a test in the garage this morning. The proto board was cut to fit into a tci plastic box, but for this test it is not mounted in the box. The input and output circuitry was patterned after the yamaha TCI boards with a few modifications. The Arduino programming measures the rpm of the bike from the pickup pulses and calculates a time to energize the coil and a time to fire it. The advance curve is similar to the tci board with idling at about 15deg and fully advanced at 40 deg. The curve ramps up from 1900 rpm and maxes out at about 3300 rpm. Had an extra circuit that would only allow the coil to energize when the engine is turning but had to temporarily disable that. still a couple of bugs to work out. Apologize for the shaky video. It is a video of a static test in the garage.
