I just completed the LH3 upgrade on my es98.

The limitations chart showed 134 datapoints (as opposed to LH2's 117 or so), but I cannot seem to find them. In fact, I have items like TTZ and SOC (which, I've Googled, and cannot figure out what they mean), but no longer do I have CMG & DMG on LH3. Surely those cannot have gone away?

Any insights would be helpful.

Welcome to the Raymarine Forum FastMarkA,

Please excuse this late response. Many LHII features have not yet been incorporated in LH3. However, when running LH3 v3.5.40 software, DMG and CMG may be located within the Navigation data group. I was unable to find any instances of TTZ and SOC within this version of software. Within which data groups did you find these data item.
