I don't know the answer to your question as it pertains to conduction angle. I do know that the older coil packs could take up to 5 ms total dwell without much trouble but the newer coil pack are happier with 3-4 ms of total dwell time. Whatís important to remember is that you only need enough dwell time to fully charge a given coil. Adding more time doesnít necessarily benefit anything and in fact I usually find it can burn out coil packs and cause misfires. Why the misfires? Iím not 100% positive if this is due to overheating or possible spark jumping. I can tell you with conviction that I have not lost power by reducing the dwell times of the STI as I have tested the lower settings on the dyno. We usually make more power because it stops misfiring.

Thanks,
Phil
