Hello , Im trying to attach a coil driver to the oem obd1 ECU to have individual coils , any inputs or help is really appreciated ,

Im using an arduino micro controller for now to control separate channels for every coil , d17a2 coils (3wire) and Im thinking to take the ICM signal to know every spark signal and then use either an injector or the CYP sensor to synchronize what cylinder goes next.

here's the link for the post on my forum and a video of the first channel test.
