Default Determine which coil fired from log

I have some logs of a random misfire I've been having and was wondering if there is a way to correlate which cylinder fired right before the misfire. I'm running sequential ignition. I'd like to be able to tell if it was the same cylinder every time.

is this information stored in the logs?

What about a composite log...that would catch a missed ignition event right?

It would catch anomalies with the trigger. If your miss happens fairly often, it's worth a try to capture it with a composite log.

Grab a normal log using the SDcard, set the period to 2ms, log the portb variable.

In the log:

1 = Cylinder 1
2 = Cylinder 3
4 = Cylinder 4
8 = Cylinder 2
