YT90SC - You actually provided a lot of good information simply by pointing out the various factors that are missing and how to properly sequence the data. I'm working on a small, irregular but constant, pulse in acceleration through all gears under load and a slight loss of torque in 2nd and 3rd. It's a very slight irregular pulse (no bucking) and I've spent quite a bit of time analyzing other aspects of the vehicle with FORScan to rule out other issues. My main challenge isn't understanding where the data (of whatever type) is coming from and why, it's not knowing what a 'normal' trace looks like. You've helped already with the 'normal' aspect via your comments.
I'll do another trace, properly sequenced/timed with RPM included sometime this coming week and post for further comment. This might be normal wear/tear on a 220k motor, but I have always been proactive with maintenance and enjoy the analysis aspects of tools like FORScan.
