Engine monitor for Arnav MFD

Would greatly appreciate some input from those who have installed the Arnav engine monitor, or point me in the right direction if it has already been posted on this site/ Most interested to know if most of the bugs are out now worked out, and if it displays “time left” for fuel/. I miss my Shadin fuel monitor and my Insight engine analizer on the Trinidad…but thats about all I miss.

Thanks in advance, Denis
