Quote: 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.
Attached is a my last run recorded on my LM-2. Maybe later when I have time I'll try to explain all that's going on but there is a lot! The converter seemed to let go on that run and I lifted, that's why the RPM drops in second gear. I can't imagine wideband tuning by reading a gauge real-time. I'm recording 7 things on my 4 input channels, in addition to the RPM channel.
Need a little more smoothing on a couple of those graphs, I think.
