It's a shame that there is not an easy way to record A/F and RPM and then display in graph form. When you see the info spread out in a graph, it is much more useable. The details and trends become apparent.

The LM-1, though a bit clunky, was the best at this that I have seen. But apparently the newer versions have not worked as well.

For anyone looking to start tuning with a wide band, I would strongly suggest getting a combo with at least A/F and RPM recording ability.




My LM-2 has worked great and LogWorks displays the recordings as a chart. If I knew how to take a screen shot with windows 7 or 8 I'd post a graph.
