The E1 universal engine monitor combines in one compact 3 1/8” format instrument all that is needed to monitor most smaller aircraft engines from two-stroke ultralight engines to medium sized four strokes such as from Rotax, Continental and Lycoming. Most automotive engine conversions can benefit from the use of the E3 engine monitor.

This device would be great if it worked! The screen is easy to read in day light. The menu is simple enough. Has a lot of potential in a small package. but I can never get it to read EGT, CHT accurately. RPM is never anywhere near correct and Tech supports answer is pretty much Keep messing with the pots on the back. No thanks. I dont trust it and would not recommend it. |

Will the E-1 from MGL monitor 4 EGT and 4 CHT as I have a Lycoming 360?
The E-1 is a four channel system. 2 EGT & 2 CHT or 4 EGT or 4 CHT are its options. You would have to buy two E-1 to monitor your 4 clynider engine or go with the Xtreme EFIS from MGL.
Does the E1 come with the 2 9 pin plugs or pigtails?
The MGL Avionics E1 Engine Management System comes with two connectors that attached to the back of the unit. The connectors are attached to 8 bare wires.
I would like to run this instrument alone side the Flight 2. My question is that, is it possible to share the rpm signal pulse from my Slick mag for both units?
Yes, pulsing signals such as RPM may be split between two units.
Will this unit use the oil temperature and pressure senders as supplied by Lycoming?
Per the manufacturer: No, not all Lycoming senders are compatible with the E1.
Is this unit approved for certified aircraft, ie TSO'd? I would like to install this on my Citabria running a 0200-continental.
No, MGL avionics products are intended for use in experimental aircraft only.
Can I use the MGL E1 to display the output from the standard engine sensors in a stock 912UL, that is the RPM, oil temp, oil pressure (20mA sender) and the 2 provided CHTs?
Yes, the Rotax senders are compatible with the MGL E1.
What size is the MGL Avionics E1 EMS?
This is a 3-1/8" instrument.
Does the MGL E1 include MAP monitoring? Also, is the display user -adjustable ( for which parameters are displayed )?
The system will display manifold pressure and rpm indicator but you have to buy the senders for the gauge. The display is not user adjustable. This is not a TSO'd gauge.
