In setting up my Gen 4 Jabiru 3300 on my CH750 STOL and doing the test flights in 2021 I was frustrated with the poor charting available from my MGL EMS data files.  I am fairly handy with Excel, but it takes time and effort to move raw data to fancy graphs.  There is also a software that you can buy for you MGL files that looks pretty good, but I found a cheaper solution.  Savvy Aviation has a well-known paid service where they keep track of your engine monitor downloads and evaluate your numbers for the certified Lycoming and Continental crowd, but they also have a free section where you can download your engine monitor data and evaluate individual flights.  The graphing functions are great and Savvy Aviation benefits by adding to their data set if they someday decide to provide service to experimental aircraft or if they expand to the factory LSA community.  They support all of the engine monitor brands including the less common MGL.  

It is not perfect, but it is free, and the graphing is great.  I would encourage the Jabiru crowd to take a look at it.  It helped me diagnose an electrical problem in my charging system by looking at the charging graphs of some problem flights.   Savvy Aviation Free Stuff
