Would this be a sign of failing probes or something else? Dave Leikam ________________________________ Message 3 _____________________________________ Time: 07:37:01 AM PST US Subject: Re: RV10-List: High EGT readings From: Kelly McMullen Not likely anything is wrong. you may want to download and graph what data you have, but you aren't going to have uniform balance at all power settings. If you have a tight spread at your normal cruise, that is about as good as you can hope for. Only if something has changed over last flight or two would I be looking for anything.

Now days you can SEE the exact number, and it makes you worry about things that would never have been a concern if you didn't have a string of real numbers in front of you. of course, now days you can use these exacting numbers to see problems coming early on too. ... so there is a benefit. It just takes a bunch of flight hours in varied conditions to start to see a real baseline normal.

The #1 cylinder was reading 100 deg hotter than the rest in cruise. Turns out to be a deposit on the spark plug. It did not show up on mag check until later. SO I think the monitor did pick up the issue before the next mag check. Cleaned plug and all is well and temps back into alignment. -Chris Lucas #40072 -----Original Message----- From: owner-rv10-list-server@matronics.com [mailto:owner-rv10-list-server@matronics.com] On Behalf Of David Leikam Sent: Monday, August 08, 2011 10:11 AM Subject: RV10-List: High EGT readings I just finished my 40 hour phase I this weekend and noticed for the last few hours that my #1 and #2 EGT temp readings are a bit higher than the rest during low power settings.

When you go to single mag the EGT should go up about 100 degrees on all cylinders. If it doesn't on one or drops off, that plug is suspect.

Here is my solution. I have a Garmin 430W GPS antenna, a stand alone GPS serial receiver and the XM weather antenna's all mounted under the cowling. No issues in 270+ hours. The stand alone GPS unit drives the AFS Autopilot and the copilot AFS-3500 EFIS. The Garmin GPS is driving the pilot side AFS-4500 EFIS. They are forward enough to have a good view of the sky. The $30 GPS receiver is this one: http://www.amazon.com/Serial-GPS-Reciever-Cable-Kit/dp/B000VUFGF8 Jim Combs N312F - 270+ hours ________________________________ Message 9 _____________________________________ Time: 07:36:35 PM PST US Subject: Re: RV10-List: Red Fuel Transducer Mount - Firewall From: Jim Combs There was a discussion about alternate mounting if the red fuel transducer. I put mine on the lower right side of the firewall. Used 45 Degree fittings at the transducer. No fuel pump fluctuations and not engine mounted. Both fuel lines are adele clamped to the engine mount to reduce vibration loads on the cube.
