As those who have the GRT EIS know, it can save a file to TXT format for later anaylsis.
I recently came across this on the Dynon Avionics forums... http://www.iflyez.com/EFISRecorder.htm It is a datalogger that monitors GPS data, EFIS and EIS data from a variety of manufacturers and collates it all into a TXT file. >From there the computer Guru's can do whatever they like for graphing it, but everything is time-sync'd to everything else. Should make life a little easier for those doing flight testing or just for those who want to trend-monitor their engine. Cheers, Rob.
