I know there are CGR users out there, hence my surprise. With the dual CGR30's (P and C) I believe I can replace everything primary, as I can with the EDM900, but will do the math for sure. The worksheet that needs to be filled out and sent in will keep me (and my A&P) honest. I forgot - yes on the CIES fuel senders, thanks for that suggestion; I was somewhat on a fence on those but yes, it simply makes sense to do it right from the start.

Thank you all; to summarily respond: - yes, if EDM900 then definitely landscape mode; I am still tempted by the format of the CGR30P/C, I'm somewhat surprised nobody voted for them; I'm waiting for my mechanic to offer his input on this as well; - good idea with moving the AP annunciator, if I decide to bite the bullet and replace the KMA24 with a PMA450B, which I might not, see below; - I have all four seats wired into the KMA24, so attaching a simple intercom to it should not need major rewiring, just the jacks and an interconnect, whereas replacing it with a PMA would require me to also redo all the avionics connections; I'll take another look, and see how the prices on the engine monitor install work out, but will likely leave this for when I redo the avionics; - does removing the existing gauges save me anything except weight? if not, I'll probably leave them in case the new sensors develop infant mortality and remove them when doing a true cleanup of the whole panel; - I have no preferences nor allegiance to brands, I just want the stuff to work well and play nice with each other; I have a slight mental preference to support the smaller guy if all other things are more or less equal. It won't be an "all in" new panel. In the future, yes, a IFD440 is an option, but the G5's are not, they won't drive the KFC200, so that will have to wait till something breaks and forces my hand or new things / interconnects appear; perhaps an Aera 660 or an ipad running the Avidyne app will eventually replace the KNS80, but then I need a standalone DME (we can't officially substitute GPS for it here). But all this is not going to happen now.

I would like to ask the good people of MooneySpace for suggestions on rearranging the panel in my M20K 231 in a cost conscious way, as well as help on deciding on a engine monitor. Any other hints for now and for the future are also most welcome. By "cost conscious" I don't necessarily mean "cheapest possible", rather "inexpensive but sensible". Work will likely be outsourced to a shop, a FAA A&P/IA is a rare sight at EPKP, one that would sign off my self-install even more so. I currently have standard analog / vacuum instruments as pictured below; in the avionics rack: KMA24, GNS430W, KY197, KNS80, ADF; in the right panel: a FT101 fuel totalizer, the adjustment panel for the remote compass for the HSI, a WX950 stormscope, TIT, ELT, XPDR and a void. The AP is a KFC200, which works well but is lacking, as far as I can tell, GPSS. Everything works and I see no signs of something wanting to fail. My primary goal for now is to install an engine monitor. I do want a "primary replacement" unit, since the cost difference vs the non-primary units is likely close to fixing whatever gauge breaks first, and I want the recording of as many parameters as I can get. I do not plan on removing the original gauges at this time. I also need an intercom. I don't think I can afford to replace the KMA with a modern unit, since it would probably mean major rewiring. So a Telex PC4 or similar will most likely go above the AP annunciator panel. Hooking it to the KMA should be simple enough. In the future I do want to replace things that break with modern devices, if cost is not prohibitive and compatible with whatever remains, but future-proofing is not a primary requirement at this time, so let's not get too carried away. Think more G5 (if it becomes a KI256 replacement) or Aspen, not G500. GFC500 only when the KFC200 breaks beyond economic repair (hoping never...). For the immediate task at hand - an engine monitor - I am thinking either a CGR30P/C combo (where the ADF indicator and the electric AI are) or a EDM900 (landscape across ADF and VOR, which gets moved to where the AI is). When I try hard enough, I can imagine a MVP50 or a EDM930 in the right panel, but it is more rearranging of stuff and I'm not convinced that the ergonomics will work. This is a stock M20K, with a GB1, so I expect it to need fairly continuous tweaking of the knobs. I really don't see them in the avionics rack, I want to keep the KNS80 for now, and moving it, if even possible, is likely a major PITA. I have, briefly, considered using a Dynon HDX / Garmin G3X / G500 as just engine monitors that I can expand into full glass cockpits later, but as others here proved, they won't really work in that capacity on a budget, and I am not ready to go "all in". Thank you all in advance!

No advice to give, just saying "congratulations". Do you have an intercooler or better wastegate? I'm jealous of your speeds...

Engine out in a single a couple weeks ago at Zurich. It is in German, but the pics of the engine (need to click the 'next' button a few times) tell the story (it ended well).

I can fit a 3.125" device (or both, with any luck) in the left panel and I don't see how I could do it with a MVP-50 / EDM930. Redoing the right panel / avionics rack would be a major undertaking which I don't think I have the guts to undertake at this time (although I probably should). If I can fit two on the left side, which is likely, I could also do a EDM900, so I think it is down to those two. I'll post a panel picture and ask for ideas later in the week, in a separate thread. Thank you for taking the time to comment!

Yes, I looked at Aspen. And the "new" "King" stuff (KI-300 / KA310) and Aerovonics. And the GFC500 ;-) What I really need now is an engine monitor. If Dynon would interface with the KFC200 maybe I could rationalize getting it for the engine monitoring features and finding the extra money by repeating "futureproofing" enough times. As of now it looks like a EDM900 or CGR30 combo go in now, and I worry about "next steps" when I get to them...

I seem to recall reading of people successfully fixing stuck ring issues (blamed on, iirc, too much low power flying - na engine up high) by adding a fully synthetic automotive motor oil (Mobil 1 0W20) to the sump a few hours before an oil change.

The KFC200 needs an attitude source, the KI256, and that is what I am asking about a rerplacement for. Since the HDX is more like a G500 than a G5 and all that... Would help menatally justifying a piecemeal approach, I for one don't see myself doing a "replace everything at once" upgrade.

Thanks for making the points above, I see the silliness of my comment when put in context.

So like the Mooney speeds advertised back in the day? :-) Hey, they learned from the best!

Like, for example, the tie-down loopy things that should be removed when not needed, as mentioned in some other thread? ;-)

Bob, people around the world go through sometimes great lengths to enjoy the on-condition approach to maintenance allowed by the FAA for part-91 operations... Don't let that advantage you have disappear by performing unneeded maintenance based on an arbitrary time limit, which more often than not based on a CYA approach... :-)

Are there any plans for Dynon HDX to be able to drive legacy autopilots, specifically the KFC-200?

EI currently has a $1000 discount on the pair, so the price is basically a wash in the overall scheme of things...

In the days of my youth, and USENET, it was called a "kill file"

In lieu of a DB9 serial port, which could be hard to find on a modern laptop, one can use a USB dongle with a DB9 connector; the standard is called RS232.

I know this is about a EDM 900, but how does the layout on a EI CGR30P work for a 6 cyl? I'm about to decide JPI vs EI and any input is appreciated.

Till the debris level reaches new highs

What is the temperature on the ground around SA these days? As in, would 20 minutes on the taxiway not be long enough for any ice to have melted away?

The "Travel John" (and Jane, respectively) lines are said to work well, too...

THIS IS WRONG. It resets the flight time (f/t) on the ADF. I don't know what I was smoking. Apologies. mine looks the same and is labelled "F/T RESET" andvbit resets the totals in the fuel totalizer; make sure your JPI EDM does not have a fuel totalizer that replaced a factory FT-101.

I think there is a G4 in the for sale section, if you can find a spot that won't require too much redoing...

Isn't that adapter still vaporware?

Or 10BASE5 or 10BASE2
