I put new EGT probes in, but that didn't help. What made the difference was reloading the current program software. Is everything else fairly steady. -------- Roger Lee Tucson, Az.

BUT I do have a fuel return to keep things moving, and the fuel lines in in the engine compartment are fire sleeved.

I did install the unit correctly and will switch wires per your advice Craig's, if Roger's suggestion to about reloading the Dynon software doesn't work.

Secure screws with LOCTITE 221." Presumably the Loctite doesn't interfere with the ground. The manual says to use Loctite 243 for the oil temperature and pressure sensors (section 79, 3.1.4). -- Craig From: owner-rotaxengines-list-server@matronics.com [mailto:owner-rotaxengines-list-server@matronics.com] On Behalf Of Les Goldner Sent: Saturday, July 19, 2008 7:56 PM Subject: RotaxEngines-List: Erratic CHT reading on Rotax 912 The forward left CHT value jumps all over the map on my Dynon 180 EMS and generally reads lower than the right sensor. I replaced the CHT thermocouple sensor on my Rotax 912S engine (80-hours TT) , and checked the wire connections but the problem persists. Has anyone resolved a similar problem on their Rotax 912? Les (PS: the CHT sensor is really pricy and I was not happy that the problem did not go away after buying it.) http://www.matronics.com/Navigator?RotaxEngines-List http://forums.matronics.com http://www.matronics.com/contribution ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message rotaxengines-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/RotaxEngines-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/rotaxengines-list Browse Digests http://www.matronics.com/digest/rotaxengines-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
