Just ordered mine. Anyone know approximately how many hours this should take (or took) to install?

Wow. just checked Mooneyspace after a long while and didn't previously know I needed this, but yes I'm in! I agree having a tie in to the gear indicator switch at some point would be great if at say 100 feet, the gear is not down and locked a very loud gear emergency warning could be potentially added which would be great if the FAA allowed this. Anyhow, Im in, website says its backordered. Any idea of how long is delivery from order? Looking forward to getting my LHS.

I have an EIS with my G500 Txi and I went through the same angst about eliminating my JPI which I had for years, and Garmin will not allow you to have any other redundant engine instrument if you have an EIS. There are more numbers with the JPI, but you can configure your EIS to display most all numbers (Except CO level if you have a CO detector), and you can set warning levels which will bllnk and turn color right in front of you so you can correct any engine adjustment without having to interpolate a number or look at a distant screen. Your detailed engine data downloads into Garmin Pilot (most of the time) or you can manually download them, just like the JPI. So I would give a thumbs up to the EIS integrated system, with the only caveat being I wish Garmin Txi would allow a Carbon Monoxide RS232 port input if you have a CO detector, as they have on pretty much EVERY other engine detection system out there (JPI, EI etc)

Prices were very fair and reasonable compared to other service centers. They figured out a a higher CHT temp issue that had previously stumped my mechanics for well over a year by being very detailed in their investigation and repair. Runs like new now! One thing I thought was different about Coast, is that they require a small deposit to reserve the time for your annual in advance which is applied to your bill. So when its your turn, they can devote their mechanics to work exclusively on your plane for that time rather than the shop scheduling as many planes as they can possibly squeeze in, with the shop assuming that some people will cancel.

PIREP - Just finished my annual at Coast Air Center at MGY, and they did a remarkable job. Very thorough and professional! Very good at diagnostic, figuring out things baffling to other centers. Hope they find a pilot able to fly all Mooneys for test flights, and get their avionics division up and running (they're working on it) and it truly might become a one stop service center of excellence. Recommended!

I think you’ll find you have fixed the surge issue completely with lowering you max MP. Good work. As far as fixing the gradual drop in oil pressure with altitudes above 11k, good luck with that! Keep an eye on your pocketbook though, I spent quite a bit on this replacing things with the final answer being hmmm not sure, you might want to think about changing ...($$$) That’s a head scratcher for all of the lycoming experts I spoke with, but everyone has theories! (The parabolic vs original tappet design theory was somewhat plausible though, but which one better still not clear) Another head scratcher theory! Thanks

3 inch variation? Wow. Didn’t know that, definitely adjusting mine!

Good graphs! Yes I believe I had mine set to a maximum of around 37, but I am going to have mine lowered soon because of my CHT issue I am noticing on takeoff and this great discussion. I have noticed that from different temperatures and atmospheric conditions the max Attained MP can vary by as much as 0.5” after being set by your A&P. So I completely agree with Don in that setting yours at 38 is too high and is VERY likely causing your surging issue in your engine trying to prevent catastrophic over boosting. if I understand this correctly if you exceed maximum by over boosting, your engine can fail completely on takeoff, At the worst possible time.

Old tappets work better? Wow there’s a thought I hadn’t considered. If you still have access to anything from lycoming saying that the old tappets work best with AF1B please send to me, as it will be helpful when I order my new engine when TBO comes up (soon) and I ask them to switch out the lifters? I would love for this yellow at altitude to be gone.

Don! Thank you! I'm going to have mine lowered next maintenance which im sure will fix my CHT on climbout issue. I went through this! Got my spring replaced which was already the recommended one I hear with higher tension, and it didn't fix the issue. So now mine like yours, oil pressure starts near redline at startup and requires a longer time for the oil to warm up (I usually wait until oil pressure is 160-165 degrees) so that the pressure is not in the yellow at full throttle forward. At altitude, mine starts to dip into the yellow in pressure above 11,000 feet which I don't worry about anymore. What I did notice is this relationship is also inversely proportional to oil temperature (higher temp, lower pressure), but there is also an altitude component to this which I have no good explanation for. Other than the one person I heard who says if I remember correctly that his M gets around 65psi all the way up to 20k with roller tappets installed, all the rest of the pilots I've talked to notice the incremental drop at higher altitudes (if they have digital gauges). I still think this oil pressure yellow at higher altitudes is an issue that we are all noticing now since we have digital engine gauges, and we get things blinking at us when we drop below 55 in the yellow. I have a picture of my old panel with steam gauges when I was at around 19,000 feet, and looking closely, my analog pressure reading was below 50 in the yellow, but much harder to notice and get an exact number.

Hi Don! Thanks for weighing in on this. Your experience is well appreciated. What did you have your mechanic set your max MP pressure at? I was thinking the other day that even 37" might be too high, as on warm days, I do get a warm CHT issue on climb. I can always just not push all the way forward which I do sometimes, but then I have to turn on the boost pump on and off manually,. Curious as to what your thoughts are to what max MP setting get the longest life out of your engine while keeping Bravo power on takeoff.

Good call! I think that explains your surges. Since redline is 38.5, I had mine turned to a max of 37" (or It may have been 37.5"), so on some days it can go as high as 37.7 but no more surges at that setting and plenty of power. When I did have it turned up to 38+, yes it did seem to get a little more power but it was not very efficient as it would quickly get my CHT's up over 400 if I didn't turn it down almost just after liftoff. Sounds like your plane is working just fine, particularly if your surges go away once you turn your Max MP down. Hope this saves you some $$$!

Very similar issue I had. As to the first issue, I found that it’s common at high altitudes in the teens that oil pressure drops below 55 and incrementally lower as you climb higher and higher. This has been present on my Bravo ever sine I purchased it and noticed it recently when I purchased digital engine gauges that give me the yellow readings on climbing. I put lots of money overhauling and replacing things and no significant change. This does not seem to affect performance. Haven’t really been given a good explanation as to why this happens (I asked several experts including some from lycoming without good answers) but I stopped chasing that one and just realized that my oil pressure will be in the yellow arc at high teen altitudes. As far as your surge goes, mine occurred when the max MP setting was too high, and on certain atmospheric conditions, on WOT, it would come close to redline and the wastegate would open to prevent over boosting which would produce surging. You should have your wastegate checked to ensure its working correctly, but mine went away when I adjusted my maximum attainable MP downwards.

Hugely helpful David and a Steve! My WOT gets me about 36-37”, ( these are on takeoff climb) so if only makes sense that my CHTs would be hotter on climbing like a banshee which then requires a power down / speed reduction to keep them lower. But at 34 I can climb all day without a cht issue, I’ll have to check what takeoff climb rates I get at that, but nice to know don’t have to spend any money on this one, thanks guys!

Greetings all! Question for Bravo owners only. I'm wondering what another Bravo owner's CHT's are on climb? I have noted that climb at 500fpm/ WOT, full rich , boost pump on, cowl flaps open, empty back seats, on an average day (like 70-79 degrees F) leads to CHT's of up to 390, but at 700fpm, the CHT's are 400, and even though I can climb at 1,000 fpm+, my CHTs would exceed 410 after about a minute or two. I'm wondering if this is typical? Since I installed a more accurate CHT measurement system I'm wondering if I am just noticing this more now that its easier to see or is there some issue I can get improved? II have had my mechanic check baffling which appears to be ok, but before I start throwing money at this one wanted to see what was typical.. Realizing that some may have "tall tales" on answering this question, like "My Bravo can climb 1,100 fpm on a blazing hot day at a CHT of 350".. right! But hopefully looking for an honest CHT as it relates to your rate of climb on takeoff if possible? Here's what I've noticed on an average day as above at near sea level. Climb rate CHT degrees F 500fpm 380-390 700 fpm 400 1000 fpm 410 + Appreciated In advance!

Has anyone tried to do this with a video camera? I wanted to see if my A20's would pair Bluetooth with my Garmin camera to get cockpit audio recorded rather than using the cables.

I was hoping by some miracle Oshkosh could happen this year, the trip across country visiting all sorts of cities, the Caravan, the Oshkosh band, those things pretty much define my summer fun! But deep down, I knew that was going to be almost impossible. Glad they cancelled it, though, as it would have put lots of people at risk, until there is a vaccine or very effective treatment for this virus. I'm now tackling my list of things I need to do "one of these days". Its very rewarding. Just did my first landing at LAX a few weeks ago (going back for another one once I get my plane decked out with cameras, huge thanks to @Skates97 for tips!). Flying nowadays is in such clear, smog free air, having my plane camera-ed out will be great. Got some of my little avionics annoyances fixed, and a whole host of other things, going down one by one on my OOTD list.

This one would work! Adding to order. Thanks Richard! John

Hugely helpful sir! Ill be buying this setup thanks! And I especially like you made the links with the smile.amazon link as makes it easy for part of my purchase to go to the Mooney Caravan! One question though, how did you connect your Nflight cable to your camera? On my Garmin VIRB, once you put the case on, you cant access the jack. Was thinking of drilling a hole in the case so that the audio plug will fit, but curious how you got yours to work. Great setup! thanks! John

I would be interested in a picture when you get it set up if you can share?

Thanks Paul! Hugely helpful

Paul, if you or anyone else still has a wiring diagram for an M20M, I would be interested in getting it thanks!

This has got to be the most horrific, ATC recording I have heard that unfortunately, I cannot un-hear, and will probably remember this voice every time I fly IMC. I won't speculate what happened, but would like to know the NTSB report final, but I sincerely hope that NO ONE is ever in a similar predicament or fate. Very sad, very sincere condolences to his family and friends.

Excellent, was planning on stopping in Omaha on the way to or from OSH one of these years, ill check it out! x2! Wow.. may need a bit of time in Omaha

If anyone travels to the West coast, would highly recommend Harris Ranch 308 for an awesome steak. Fly in to airport, walk to restaurant, with hotel if you need. Relatively narrow runway, but if you're comfortable landing near the centerline, its absolutely no problem for our Mooney's. Discounts for pilots. I'm taking notes as I'll be looking to travel to some of the other restaurants all of you are mentioning above after Corona season.. don't mind a $100 yummy steak stop!
