My super fancy scan tool software was not offering misfire data and I just assumed it was a function of the PCM rather than the software. I thought hooking up to an engine analyzer was my only option to gather ignition data. Anyway, I ended up dropping $40 to have a local guy plug in his fancy snap-on scanner. It immediately flagged #4 as misfire and once I swapped the plug wires the misfire moved to #3 so I knew it was a bad wire.
I am now better educated regarding the limitations of the scanner software I select and am looking at alternatives that support mode 6 among others.
I am 95% NovRun ready. Just have to install my new ram cylinder.
I've been using this scanner on my ODB-II vehicles with good success. It was $80 on sale but has a lot of features. OBDLink MX Bluetooth Scan Tool Part #426101 https://www.scantool.net/
