Gotcha...I'll give that a shot. Should I turn on the "sync after every cycle" back on? I originally followed the instructions from the Speedy wiki page, but found I had better luck not using it.
I followed what you meant by "electrically noisy" before. I just noticed it was mechanically noisier than others I've used in the past so it made me wonder...
I had some success with ferrite cores and an O-scope last night. I found random spikes of 1.5v on the cam and crank signals. After installing the cores, the noise was limited to under 500mv. One thing that did concern me was I couldn't always get the larger spikes to show up when the cores weren't
installed. I would move the harness around and it wouldn't always hit 1.5v but rather be around 500mv. Either way, with the cores installed I got a consistent value that was always lower.

Set offset to 0 and adjust cam manually.
The decoder is not written to have an offset and can cause issues.
Noisy as in electrically.
If the issue only happens during cranking then it is likely a culprit.
