It has been months since iv'e scanned my truck or anything else,but in a couple day's i will be moving my 10,000 lb trailer 600 miles so i decided to take some timing out to be safe under heavy loads, all my other channels work fine but nothing shows up for retard. The only thing that has changed is i updated to the latest mpv download, nothing else has been touched. And the graphs are still as they have alway's been.
Re-poll for supported parameters. Remove the knock retard channel and re-add it back to the channels list.
That usually works to fix that.
2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.
If you don't post your tune and logs when you have questions you aren't helping yourself.
