Thanks for posting the charts. There appears to be a good amount of sample speed aliasing. Do you know if the sample speed (aka: scan rate) is any higher if fewer 'channels' are selected? You know, like uncheck the boxes for the data you don't want. I think that might have increased the scan rate for the GS-911, but I can't recall.

Was the fuel injector pulsewidth, or fuel rate, collected? If the resolution is high enough it might be useful as well. In order to see small changes better you might need to put some gain into the data, and shift the signal with some offset, then limit the y-axis range when building the chart. (Excel techniques to increase the y-axis resolution)

Edit: ooops, I meant y-axis
