From my experience the RV' float senders don't 'read' the last (top) few gallons, it's the bottom few that really count. Maybe this is your situation ? :) Jake J

Would it not be better if Dynon now supplied a 2 wire sender as s'standard' issue ? - it sure would save a lot of time for all with troubleshooting/questions. Jake J

The owner just pressed the button to turn it on - has about 90 hrs on it since installed. We could wait and see if it happens again ? Jake J

Just had a D120 shut itself off a while after engine start, engine battery and charging system was ok.  Turned unit back on and all now ok - Is there anything I can check if this problem presents again ? Jake J

Rolly, Why I asked about the EDC10A (magnetometer) is you need to also update it as well when doing the EFIS ;) Jake J

Did you also do the update on the EDC ? Jake J

Ken - FWIW I doesn't appear to be the Dynon (was replaced and still the same symptoms - I've never had a faulty unit) and your connections seem solid (crimp and soldered) however I'd thoroughly recheck your wiring ie make sure they ARE going to the correct sensors etc. I found a customer who...

Hi Paul This is a wild guess but may apply - does the fluctuation occur with changes in RPM ?  If so, temporarily disconnect the MAP line and check again. I once saw similar issues with an Encoder connected to the Manifold Pressure line (Helo) had 3 Avionics shops baffled. :o cheers,  Jake

Will check it out - was aware of the problem in an earlier version reading approx 20 degree too high.  Fairly sure we downloaded 4.0 however. regards,  jake

Dynon Support ??

Hi geoff The problems with the autopilots are not unique to them only otherwise why would we talking about this on the Dynon site - see my point :) Went flying today and discovered that initially the a/p would lock on ok for 2 goto way points then the plane would go around in circles. This...

We have an RV10 that's showing an approx 8 deg C higher than actual (checked with a calibrated gauge) right through the range. Aircraft has 2 x engine ground straps and a separate ground from the aft battery to eliminate any possible audio or sender issues - so it's more likely grounding isn't...

Hi Geoff From my experience last week there are still some issues with the Avmap with the lastest software version (Vers confirmed by Avmap,Italy) eg when engaging an autopilot it would initially start to intercept a track but then start wandering followed by going in circles.  So there appears...

Is there any way of checking whether the pitch sensitivity is too high/low as it appears to move much faster up/down than air driven gyros ? jake

Re: Picking my EFIS.  

Just press the NAV button again (when Nav frequencies are selected) and voila! you have both nav frequencies monitored. jake

Peter Give me a call re the KX 135 - there are some issues with these and also the KLN 89/90 models as well. cheers, jake

Re: Dynon GPS Support- AVMAP EKP IV From my expexperience there have been some NMEA datastream interface issues with the Avmap EKP IV mainly with autopilots including the most recent SoftwareUpdate 2.04.110R - 2007-09-26 - an autopilot will work on the ground but looses the Gps (NMEA) at speed...
