Yeah the problem with just upping the dwell time, it gets the ignitor super hot, which i dont think is a good thing. I mean, it can handle some intense heat, as that thing is bolted right by the cylinder head on the 4g63 engine. I also ran slightly larger plug gaps as well, which could have contributed to the misfires, esp when a weak coil charge is happening all at once. I ran around .032" gaps, and still run that with the crane box.
