The biggest difference is the OBD2 "real time" viewing/logging as stated above. So to answer your question about "old school" cars like ours, the OBD2 features won't be of any use and the LM-1 will work fine.



That is one way to look at it. Another is at what rpm does your engine go lean or rich?
With add ons you can get rpm on the LM-1.
The LM-2 you just hook up a wire to your MSD rpm/tach wire. Then you know what your carb does at launch, on the shifts, at idle if you have a couple feet of pipe after the sensor. I like it as a VERY useful tool for tuning! Don
