Ladies and gentlemen after months of waiting and preparation, I've finally got my EDM 830 installed! I couldn't be happier with the job that Auric Avionics did in installing it, unfortunately I can't post pics right now but they'll be up as soon as I can. Installation took 39 hours so right where I was expecting. However on the flight back home I noticed a lot of things that seemed weird. First off the MAP was always about an inch above what my factory gauge was reading and the RPM was always about 100rpm lower than what my factory tach was reading. As far as leaning my cylinder EGT spread was about 100-120F I'm not sure if this is a big spread, I flew in a cirrus yesterday that had spreads of 30F. I tried leaning LOP but it seems like once I peak the hottest cylinder I can only go about 20-40F cooler on that cylinder before my engine starts running really rough. Is it just impossible to get LOP with my engine or does that mean theres something wrong? Also on climbout my hottest CHT will always go above 450F and start the alarm, I'm usually doing about 100mph for the first 400ft and then I start to transition to 120mph, but does this mean I just need to pull the power back quicker on climbout? My fuel flow and fuel used has been very accurate so far so no complaints there. I've also noticed that on takeoff when I go full power my %HP only gets to about 75% and I'm around sea level all though it is pretty hot. I think this partially has to do with the fact that I've noticed my OAT on the EDM doesn't match up my other OAT gauge I have. It reads a lot higher on the EDM, but my other gauge matches up better with the temperature that it feels like outside as well as what it says the temp should be on the winds aloft charts. So I'm wondering was the sensor installed wrong. And finally my carb temp was not what I was expecting. When I'm taxiing it says its above 100F even when its 85F outside and during cruise it will read about 7F warmer then the outside air and only when I start descending do I see it drop to the OAT or slightly lower (and this is compared to my non-EDM OAT). Thanks guys and sorry for the excessively long post.
