So we have established that one must ignore the UMA install guide as far as the wires chosen to connect the gauge to - on the 914 it is different - I will let UMA know how confusing this information is. Now I know which of the white wires to connect the gauge to, it does raise another question - since the UMA gauge requires that one of the signal wires is also connected to GROUND, is the Turbo Control Unit (TCU) fussy about which one ? Am I likely to short out the TCU in some way, by connecting one of these wires that exit the TCU and connect to the UMA gauge to ground ? I don't want to make a meal of this, but the TCU is a costly bit of kit to replace and I do not want to damage it of course. Any thoughts ?

I use 98 RON most of the time. 95 RON if 98 is not available and on very rare occasions, when no ULP obtainable, AvGas. I have always used 98 RON on the assumption (hopefully not false) that if the fuel had been adulterated, with other fuels (lower grade ULP petrol, Ethanol blend or diesel) then I am burning at least the equivalent of 95 RON. So my advise is; Be conservative with the way you set up your engine/prop -------- 46 Read this topic online here: http://forums.matronics.com/viewtopic.php?p=501547#501547 ________________________________ Message 3 _____________________________________ Time: 07:45:34 PM PST US Subject: Europa-List: Europa Classic Pre Purchase Advice From: "Griffo" I have just completed my finale purchase inspection of a Europa Classic. If the purchase proceeds, I will probably replace the transceiver As you will know the Europa's composite skin facilitates the installation of an internal transceiver antenna. I this case a dipole, in the vertical tail/fin. My question is: Is the dipole inherently "tuned" ? or could it require SWR adjustment ? In my research, I checked every Europa Mandatory& Recommended Modification - all Mandatory's have been done EXCEPT a LAA "Standard Modification" No SM11906, Issue 2, "Stabilator Torque Tube Drive Assembly Your comments/advice on this omission wold be much appreciated -------- 46 Read this topic online here: http://forums.matronics.com/viewtopic.php?p=501549#501549 ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message europa-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/Europa-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/europa-list Browse Digests http://www.matronics.com/digest/europa-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.
