V7.5.4 Build 66
V2 FW 2.05.20

I was going to try logging RPMs on my LLY while disabling injectors, but with only RPM (SAE.RPM) selected, I get the message "One or more _DMA PIDs are selected. This Duramax ECM can only scan _DMA PIDs in Dynamic or Stream Scan Mode. Please change the scan mode to Dynamic or Stream (menu: Edit -> Properties -> Logging -> Scan mode) before loggin _DMA PIDs." (logging is spelled wrong ) The problem is it was in either Dynamic or stream-fast (I don't remember which), I tried Dynamic, Stream-Slow, and Stream-Fast and all got the same message. Also, SAE.RPM isn't even a DMA PID, is it?
