Do you mean the PID "Spk Adj"?
Ignore it. It goes up and down all the time even when Actual Spark Cyl 1 is relatively flat. I've stopped even logging it. imo it has no actual value.
Logging my
Rev B list gives you nearly every PID you need to tune and its still logs pretty fast ~.15s per sample or ~7 samples per second.
Try logging with the laptop to see if its faster. A new crom update to the Trinity ramped up my logging stream up to ~60-70 samples/second and thats when logging +32 PIDs.
