There are pids that indicate the per cylinder misfire counts, and these are loggable with V1 and V2 (and any advanced scanner)...

log at these pids:
GM.MFCYL1C
GM.MFCYL2C
GM.MFCYL3C
GM.MFCYL4C
GM.MFCYL5C
GM.MFCYL6C
GM.MFCYL7C
GM.MFCYL8C
GM.MFTOTAL

on the PIDs tab, select those pids (and the usual ones, SAE.RPM, SAE.MAP, SAE.MAF, GM.TP, GM.SPARKADV, ...),
within the PIDs tab click the Save Pids button (give it a filename),
then click the Connect button (green, upper left),
then click the Record button (red, bottom middle)...

when done logging, click the stop button (blue square, bottom middle), and save log to file.
