My knock sensor rarely goes off. And I'm dyno tuned. I keep count of knock count too and very rarely do I have a number in there. Your ECM will track knock count during an ignition cycle, so that number is accurate in torque. As far as other numbers in your torque app....it's not really all that great for data logging. You can get the jist of what your engine is doing, but it's not very good to make a decision with it. For instance I have mine set to "sweep" the sensors every 0.1 seconds. Unfortunately because it's writing as well, it doesn't "update" the information for about 0.7-1.0 seconds. So a lot of the entries on the sheet will be the same line after line. For instanace, i'm looking at one of my old logs and my numbers didn't change for 6 lines, which was .8 seconds and I was at WOT. My RPM on the sheet jumps from 2893.5 to 4251. So that tells you how bad the log is.
