Again, how would you do that ? I have a digital thermometer so would I have to get some water hot and stick the thermometer probe and the CHT probe in there together and see the difference in readings ? You mention grounding. Would I have to run a ground wire from the CHT probe to the engine ? I remember when I purchased the CHT kit the instructions mentioned that they could be off by as much as 75 degrees.

From: "royalevo9" --> JabiruEngine-List message posted by: "royalevo9" Hi All, New to the forum. Thanks to Andy Silvester for bringing this new site to my attention via the Yahoo Jabiru forum. Matronics looks very good on first inspection. For information my Aircraft is the first Jabiru engined Tiposy Nipper and my little donk is probably the oldest 2200 jab flying. It is engine number 17 ! :D I am an Aircraft Engineer by trade and am fanatical about all things aircraft.I am also a keen motorcyclist (Ducati 851) Other interests are model aircraft and bird watching. I would be most interested to make contact with any tipsy owners here in the south of the UK Kind Regards to all Pat G-ASXI Read this topic online here: http://forums.matronics.com/viewtopic.php?p=30608#30608 ________________________________ Message 3 _____________________________________ Time: 07:51:49 PM PST US Subject: JabiruEngine-List: Re: engine monitor problem From: "Jim Stone" --> JabiruEngine-List message posted by: "Jim Stone" When I calibrated my CHT's I set up about a pint of engine oil in a flat bottomed pot. Heat was provided by a fondu warmer. I got the pot a 'Bed Bathe & Beyond as a lidded canister for about $5. (My wife said OK to using the heater, but not the matching pot.) This gives a reasonable temperature ramp and can go to above boiling without agitation. I use a couple twists of safety wire to keep the sensor and thermometer probes together. A heavy alligator clip provided the ground. The ground should go directly to the engine block. My sensor outputs shifted by a factor of 3 between grounded and ungrounded tests. My sensors have a metal mesh shield but it turns out is is just for abrasion, it was not grounded at either end. The sensor also had a resistance to ground in the low milliohm range. Obviously, in use the grounded configuration is the real world environment. -------- Jim Stone Jabiru J450 N450SJ Clearwater FL USA Read this topic online here: http://forums.matronics.com/viewtopic.php?p=30742#30742 ________________________________ Message 4 _____________________________________ Time: 08:12:35 PM PST US Subject: JabiruEngine-List: Re: Ram Air Duct Installation From: "Jim Stone" --> JabiruEngine-List message posted by: "Jim Stone" Hi Bruce, Send me your Email address and I'll ship you a couple photos. Also the new Jabiru kits have ram air ducts that have the plug wires inside rather then sticking through holes in the sides. Which configuration do you have. I modified my old ones. There have also been suggestions to add a exhaust elbow to the back of the ducts to direct air at the mags in hot climates.
