was the problem because the coils used more current and the edis could not drive them in parrell?
Yes, I feel that was the problem. Since then, I understand others have wired them in series and fired them OK. I would question if there's enough dwell time at high RPM to do this, but no one has reported running out of ignition at high RPM with them in series.
Another interesting setup might be to use Tundra coils, or other type that have integral igniters, wiring them in parallel again, and this way, the EDIS8 module isn't seeing the high current; it's only being used as the "switch" on the low current side. I don't know that anyone has tried this yet, but I think it could work :idea:
