Doppelganger, I should add that, despite the error code, there was nothing wrong with the cam angle sensor, after fixing the wiring for the crank angle sensor I put the original cam angle sensor back in just to see, it has not thrown an error or acted up at all. The entire issue was the wiring for the crank sensor.

Since you have an aftermarket ECU, it would be simple to replace the OEM coils with better coil on plugs or coil near plugs.

Coils are wear items and degrade over time. .035 gap is on the higher side. Plus gap should be set with a feeler gauge or a real plug gap tool. Eyeball won't tell you if you are a couple of thou off--and a couple of thou could be the difference between getting a good spark or not.

After speaking to a few other people, it seems like it might be the coils indeed. I guess pushing them pretty hard for so long and getting them extra hot at the track causes them to degrade. Unfortunately since it's not something that happens on the street (or hasn't yet) getting another set of coils won't be in vain. A full COPS setup would be nice, but budget is only going to allow me OE replacement coils for now.

You know, come to think of it, I've heard from other people having issues with cam sensors on 01+ cars when they get particularly hot since it's right on the side of the valve cover. Dunno if those sensors just die or degrade though...but I wouldn't mind taking a look at both the cam can crank sensors.
May not be your problem but it is worth investigating. Long thread about it here, with some links to other good discussions.
