I have been looking at options for a reasonably affordable engine monitor that will fit in or on top of a standard 3 1/8" instrument hole. So far the monochrome LCD MGL E1 EMS is definitely the one to beat at $345 (not including senders), especially as the senders are connected directly to it rather than through a separate engine monitoring box. The display is a little sad, though, and I wish the tach readout were bigger. The color MGL Xtreme EMS is nice but a big step up at$1265 including the engine monitoring box but still less senders. Are there any other options that I am missing or than the very expensive ones? Let's say under $500 ideally or under$1,000 in a pinch.

Alternatively, are there any affordable interface boxes that would allow you to display engine parameters on a little Android or iOS device?

Cheers,

Matthew

I’ve been weighing the same options for about the same reasons – space, budget and reputation. I like the Mini, but have poured over the E1 and F1 MGLs and keep coming back to them… alternatively, the GRT old standby, with flight readout options…

The truth is, I like steam gauges (not being of the iPod generation), but not the space consumption or weight of them… I recall flying with Roger over at Zenith and finally saying… “okay, I give up, where is the ball…” on the impressive, but confusing, digital display… In any case, I keep coming back to the MGL E1 – although I’m probably about a year and a half away from needing it at a minimum…

Similar thoughts here, thinking about a VP-2, in which the instrument panel is built in to the main spar bulkhead so unplanned holes are to be avoided. The stock arrangement is an aluminum panel over a 12" x 3 1/2" rectangular cutout plus two optional 2" holes. The main panel only has enough space for three 3 1/8" gauge or four (maybe five if staggered) 2 1/4" gauges. Then you still have the two 2" holes. I'd like to have ASI, ALT, RPM, OP, OT and ideally CHTx4 and EGTx4 for early warning of engine issues. I would prefer to go with no electrical ssystem, just analog, mechanical gauges and a tachometer and low oil pressure light running off a small battery. That's certainly possible with all analog instruments, but the weight does add up and the panel gets cluttered. The compass would go on top in any case.

Whatever I do will probably have some redundancy… I’m unreservedly VFR and planning to run a big-gauge ASI and a manual/capillary oil-pressure regardless of what I may do digitally… I figure if all else fails that will give me enough information to get back on the ground when the techno-gizmos die. Oh, and a voltmeter -- since I’ll not be running a magneto…

I would need the voltmeter, too, with or without magneto, forgot that.

I was lookin for a long time for an affodable EMS and finally, I made my mind on an minEFIS MGL Xtrem.
In fact, it's not much more expensive as the EMS option, but has some basic EFI/GPS functions that could be useful in my Experimental plane.
An added point was the SD card logging feature that allows me to be able to compare objectively the influence of modifications I make on my plane.

I like the Xtreme but am not really happy with the form factor. I'd rather have fewer functions, the E1 EMS would be great (it even monitors voltage and records hours) except for the drab display and maximum of four CHT/EGT inputs. A very similar model but with a color LED screen or even a bright monochrome OLED screen and the ability to monitor eight or more CHT/EGT inputs would be perfect.

Since you mention something hooked up to your tablet, I figure I'd mention the iLevil. Pricy but kind of cool idea for AHRS.

Interesting... was not familiar with this techno-gizmo...

You have everything what you're need in one small box.

Looks pretty impressive if one is using those powerplants -- do you know, is there a generic model for the rest of us...?

Given the current exchange rate, that seems to be about \$1200-1400; assuming VAT can be avoided... (?)
