That’s why I suggested you call Aspen directly. I suspect some of the busier shops aren’t providing accurate information due to their scheduling issues... take it for what its worth. Sent from my iPad using Tapatalk Pro

If you are working with an avionics shop, you may want to check with them directly. Mine was scheduled for November, just before Thanksgiving. It was done in about 10 business days. Sent from my iPad using Tapatalk Pro

Had the same failure yesterday. Momentary rough running. I think the mag was bridging the gap but I did see a lower EGT, not higher as you might expect running on one spark plug. When placed in a spark plug test box, it did not fire. Sent from my iPhone using Tapatalk Pro

Then explain how most Cessna 177s sell for more than a Mooney of the same age and condition? This site is NOTORIOUS for self defecating on our plane’s values. Sent from my iPhone using Tapatalk Pro

You got me on that one. I didn’t install the 900 in my plane so I have no clue what fittings were used. I suspect one IAs or AP guys can answer that. Sorry. Sent from my iPhone using Tapatalk Pro

This may help you. It is the wiring diagram for the left inboard and left outboard senders. I have 4 CiES senders running in frequency mode. Few things to note. 1) The outboard sender’s blue wire connects to the gray wire for the inboard sender. 2) You will want to make sure you use the JPI provided harness and run the ground (black) and signal (blue) to the JPI’s wire (CiES black to JPI black and CiES blue to JPI’s white). The instructions provided by CiES at that time talked about grounding them to chassis only. That gave is sporadic readings. I believe the harness is for JPI’s P5 connector (it’ll be marked). 3) I also grounded the CiES senders to the chassis by attaching a wire from one of the attachment screws to the airframe (verify conductivity). 4) The biggest pain is running the wires from the outboard senders. Don’t be tempted to use the factory original wires. Get a good quality shielded wire (Aircraft Spruce sells them). - if you need numbers, let me know. Don’t be too shocked that the CiES senders don’t look like the factory resistive senders. Just make sure when installed they have full range of motion. Sent from my iPad using Tapatalk Pro

You should have 4 senders. You should have 2 tanks. Even with extended tanks, there are only selectable tanks. You will want frequency as long as the 930 supports it. Sent from my iPhone using Tapatalk Pro

Why does this new thread feel like a drive-by shooting?

Interesting that they wrapped your's up in a heat shield. Where was it mounted?

I agree. The cost difference between the two is insignificant. BTW - TIS-A is starting to go away.

Mine is on the firewall on the pilot’s side. Should be a red unit. Sent from my iPad using Tapatalk Pro

Seeing that they used FL000 for their altitude, my guess they were on the ground. If they were airborne, wouldn’t they have reported their actual altitude as something in the air? Sent from my iPad using Tapatalk Pro

I hear ya. My panel didn't just end up looking like this. I went through phases and I wished I had taken the time to better plan the panel. There were two other updates to the panel before I ended up with what you are seeing now. Take your time. The hard part is that as soon as you think you're happy, one of the avionics companies introduces something new. With the exception of the Max upgrade, I am going to do my best to resist the urge to do another upgrade. But those new GTN products sure do look nice. Inner self: "Stop it you moron!"

Yes indeed. I am the knucklehead who spent all this money to make it look this way.

It looks pretty small right in front of the pilot!

I think based on the size of the gauge, it will fit. The bigger issue is that being all the way over to the right, it will be really hard to see. The font size on the GI 275 has to be pretty small. You may want to see one in person and compare. Also, it looks like it is an expensive gauge (starting at $5,295). I suspect that there will be additional charges for extra probes that you may need. https://buy.garmin.com/en-US/US/p/719027/pn/010-GI275-08 ENGINE-INFORMATION-SYSTEM-05202839-d316-44ed-9fdd-b257cb391674.webp

Your 64 C is HIGHLY modified. I don't believe those gauges are factory original (or the yokes or the panel, heck almost anything! [emoji4] ). Are they? I thought the 60 vintage planes had the square gauge block group on the right side. I see what you mean by the real estate problem. The issue with the GI 275 will be the size. It fits into a 3.5" hole, not a 2.25" one. You would need to do some serious redesigning to get anything else into the panel as it sits today. You need to get the Aspen Max PFD & MFD and then you can dump the ASI, altimeter, vacuum AI and the second CDI.

I would check the accuracy of the gauge and probe as TheLachlan suggests. Your gauge before start up should be reading the ambient temperature or somewhere close to it. If the hot water test shows the gauge or probe has an issue, I would check with Alan Fox or just open an open request to see if anyone has a Mooney cluster gauge set or probe they could sell you cheap. It does sound like an issue either with the gauge or the probe. I know you indicated that you were considering a JPI down the road. Since you have already have EI primary gauges, if the gauge is suspect, you might consider dropping in an EI primary oil temp gauge if you aren't ready to making the big commitment to the JPI.

If you want to dump your Swiss watch now Erik and keep the KFC 200 running, it looks like you need the GAD 43e (provided it interfaces with the GI 275 or is even needed at all). The GAD 43e is the digital to analog converter. If you later move to a GFC 500, I think you may need to drop the 43e in favor of a GAD 29B (again, the GI 275 may already have this built in). Easy solution to all this. Just give the avionics shop your wallet and ask them to make it work.

Mine were upgraded with Jaeger's spatial design. Maybe check with Bruce Jaeger to see if he can sell you the parts.

I love my ESI-500. It's a solid unit and with the Nav & magnetometer added, it does everything a self contained AI should do and more.

If you are a stock holder of Garmin, this is a "breakthrough". It is another way Garmin has figured out to separate you from your money.
