    D180 GPS-connection, but no course indicator

    Thanks, that was the solution. Now everything works as it should

    Rotax oil pressure fluctuations

    We fixed the volatile CHT (and cooler CHT in climb :O): It was the connector to the CHT probe.

    D180 GPS-connection, but no course indicator

    Checked the connection: The D180 receives GPS data if output of the Garmin 496 is set to either: Input NMEA, output NMEA, forced 4800 baud or Input Aviation, output NMEA and VHF, forced 9600 baud and the D 180 is set to either Input Auto or Input NMEA and the baud rate is set to either Auto...

    D180 GPS-connection, but no course indicator

    I wasn't clear, sorry: Course information from the NAV receiver (VOR) isn't there anymore as the radio replacement doesn't have NAV capability. My point is that the serial data connection between GPS and Dynon D180 is established. GPS data displayed by the D 180 are: calculated wind, UTC...

    Rotax oil pressure fluctuations

    Thank you for the clarification! The information you added helps differentiate worrisome pressure value displays from normal behaviour. I wish Rotax would have done this too. Something loosely related: I had a firmware upgrade from the version approx July 2007 to the actual one from March...

    D180 GPS-connection, but no course indicator

    After replacement of the NAV/COM Garmin SL 30 with the Trig 96Y (which should be plug and play wit a Trig-supplied adapter) and Dynon software update, everything works fine except the course indicator. GPS is a Garmin 496. Previously working: selecting NAV or GPS as nav data source using GPS...

    Rotax oil pressure fluctuations

    To sum this up: we systematically examined most of the factors that could affect oil pressure indication in the cockpit. These factors are: 0. div Mass/sensor cable connections Vibrations, heat affecting the sensor 1. Oil pump 4- and five-star rotors of the oil pump Oil pump housing oil...

    Rotax oil pressure fluctuations

    We did that: heated sensor externally with air pressure: no fluctuations of voltages or dynon instrument. This sounds too tempting to be true. With an mechanical gauge, we see the fluctuations. We saw them with old oil pump housing, old pressure valve spring, old ball, old rotor as well as...

    Rotax oil pressure fluctuations

    What leads you to this assumption? Both the new-type Rotax-supplied and the Kavlico sensor show fluctuations when connected to the Dynon while the values themselves are correct and the engine appears not to have any real pressure fluctuations. I think we will switch to the VDO-sensor rotax...

    Rotax oil pressure fluctuations

    An update: Kavlico sensor, Dynon-Display https://cloudstorage.uni-oldenburg.de/s/9SnWCPDjxSSuCDr with fluctuations Kavlico sensor, analog instrument https://cloudstorage.uni-oldenburg.de/s/yK1wZiaqBsZh8op no fluctuations This appears to me to point to the Dynon EMS. What we checked: Rotax...

    Rotax oil pressure fluctuations

    Every value (RPM, MP, Oil temp, CHT, IAS, Alt ...) is normal under all conditions except the oil pressure when oil is hotter than ca 60 deg C/140 deg F. Thus if the engine is off, value dispayed is 0,something bar oil pressure as in the books for the new rotax sensor. We did not monitor...

    Rotax oil pressure fluctuations

    That's what you see in the linked video: simultaneous reading of the Rotax-Dynon installation and an independent (battery powered) Sensor-Bluetooth-phone display. The independent Sensor doesn't show the fluctuations.

    Rotax oil pressure fluctuations

    That addendum from 2012 supplements the installation manual H from 2010. It refers to the Dynon-supplied Kavlico sensor, but not to the Rotax-sensor. Or is the Dynon-supplied Kavlico-sensor identical to the Rotax-sensor and are you saying that the new installation scheme diagram with 5V refers...

    Rotax oil pressure fluctuations

    The Kavlico is the Dynon-provider sensor, right? Don‘t know the make of the Rotax-provided. The wiring diagram I uploaded appears to reflect the one at page 3-6 of the Dynon  D180 installation manual. As I understand it, it is a voltage divider. Measurement is done at pin 6. The old Rotax/VDO...

    Rotax oil pressure fluctuations

    Hello! We are desperately looking for some good idea ... Situation: Rotax 912 ULS from 2007, 600h, with the old VDO oil pressure sensor. Dynon D180 as EFIS/EMS instrument -Shortly after takeoff oil pressure fluctuations from normal 3.x to 1.x. Not reproducible on the ground or at the next test...
