ROTAX Logs Vs. Garmin Logs

I went out and acquired a Level 2 ROTAX Dongle and have been Playing with the data.

I have a Montaer MC-01 with 915Is and dual Garmin G3X’s.  The Garmin records all the Engine Data including CHT’s, EGT’s, Oil Temp, Coolant Temps, RPM, MP, and other data.  What other additional data does the Rotax Dongle collect that I’m not getting on my Garmin data?
