Please see this log, cam and heads Fbody with 4.56 mostly dialed in
Both the RPM and MPH are wildly different between the channel list and gauges during playback.
Which one is real and why is this happening?
Thanks (log attached)Attachment 107648

The channel list on the left is displaying the exact sample values, while the gauges are interpolating for the sake of smoothness. The difference normally isn't too noticeable, but this log's sample rate was fairly low, so that makes it obvious.
I assume you're on the v3.1.4 firmware... If so, we have a v3.1.8 firmware update in testing that includes performance boosts for GM vehicles specifically. I hope to get that into the public beta in the near future, but we can get you access a little sooner if you submit a support request, include your MPVI2 serial number, and tell them that I asked you to do this so that we can put you on the MPVI2 Alpha firmware list, specifically to resolve a standalone data logging issue. If you link to this thread, that should help clear up any questions they have.
Done, thank you very much.
Request #is 2368 and I did include all the info and the serial number. I appreciate it and I look forward to working with you to improve this.
Just to give you an update Weston, I am on the Alpha firmware now and have submitted my first few logs to Chad at support. Thank you again.

Thanks for the update. I can see that Log 0013 is definitely using the GM VPW speed boost that's in v3.1.8, as it's a consistent sample rate and is about 5x faster than before. 11 and 12 don't appear to have the new method active, so those may have been recorded before the firmware update was applied, but they were still somewhat faster than your previous log just on account of having less parameters selected.
yes agreed sorry about the mistake. I will let Chad know as well. Of course all the subsequent logs will be correct. :) At least we can see the difference lolQuote:

also plugging in a vacuum line that was completely disconnected and bleeding the clutch.
Not sure how easily those changes can be spotted in the datalog. Drove the same way (normal)
I have too much fuel getting into the oil and it runs rich at idle...
