If you are redoing your panel, consider a primary JPI EDM. With the 900 on board, you can remove many of your old engine gauges, open up valuable space in your panel, and fly with peace of mind knowing the JPI will alert you instantly if any of the parameters exceeds the programmed limit. Like the 730/830, the EDM 900 is offset, and can fit both directions in your panel. Using the USB port data can be downloaded using free EzTrend software, or easily updated with a thumb drive. Non certified information can user configured. The EDM 900 is a TSO’d, compact and very easy to use and read in flight.
Not only is the EDM 900 TSO'd (available as non TSO'd for experimental aircraft as well), but all of the functions covered by the EDM 900 are TSO'd and STC'd as PRIMARY functions.
