Doug G. Posted March 13, 2014 Report Share Posted March 13, 2014 I don't know if this belongs here, but I cranked up today and the Dynon had a red X through the oil pressure gauge. Since this is the first time I have started the engine since I updated my Dynon displays I am wondering if that is the issue. Does a failed sensor give a red X or just an indication of no pressure?

BMcCand - N248CT Posted March 13, 2014 Report Share Posted March 13, 2014 Hi, I've got analog engine gauges . I had the oil pressure sensor fail twice, at about 300hr intervals. Pressure would swing from 20psi to offscale high, rapidly. I'm not sure how the d120 would respond. I finally put in a Lockwood sensor relocation kit, at about 600hr, now 775 with no more trouble. Sensor failure is likely if the sensor is still up at the oil pump. Oh, one simple thing to check is the security of the wire with the nut at the sensor !

Farmer Posted March 13, 2014 Report Share Posted March 13, 2014 I have seen the dreaded red X. CTLS at 11 hour since new, replaced the Honeywell oil pressure sensor and all was restored to normal. We completed the update Dynon skyview from 5.? to 6.2 and it was very disappointing. Not nearly the options that Dynon is capable of. Maybe in a couple of years. Spoiled by exposure to the 7.? Better than before but not nearly enough. Senior citizen here FD, let's keep moving, I don't have forever. Enjoy airplanes and alway will want more.

Roger Lee Posted March 14, 2014 Report Share Posted March 14, 2014 Which Dynon's? D120 or Skyview? Bad sensor or broken wire or disconnected wire. Usually a bad sensor will give some reading. Link to comment Share on other sites More sharing options...

Farmer Posted March 14, 2014 Report Share Posted March 14, 2014 Roger Bad sensor I was told Instant Red X while airborne no other warning, high temp, etc. I just kept going on that 6 hour and 20 minute flight. unit supplied by FD and change out by Tom Baker 2011. No further problem. Farmer Link to comment Share on other sites More sharing options...
Doug G. Posted March 14, 2014 Author Report Share Posted March 14, 2014 I'll check the wiring first. I see that LEAF has a new sensor for less than $50. (Assuming it is the same type. Link to comment Share on other sites More sharing options...
FlyingMonkey Posted March 26, 2014 Report Share Posted March 26, 2014 Doug, if you don't have the relocation kit from Lockwood, I'd highly recommend it. I went through two VDO senders in 30 hours when it was in the block, and my pressure indications were often uneven between 20-45psi. Now that the Lockwood kit is installed, it's 70psi on startup and rock steady 45-50psi in normal operation and never varies from that range.

Doug G. Posted March 26, 2014 Author Report Share Posted March 26, 2014 Turns out the problem isn't the sensor, but the software update. I'm waiting for a fix from FD. Link to comment Share on other sites More sharing options...
Anticept Posted March 26, 2014 Report Share Posted March 26, 2014 As much as the skyview looks neat, with all the problems it seems to have, I think I rather like my D100 series Link to comment Share on other sites More sharing options...
Doug G. Posted March 26, 2014 Author Report Share Posted March 26, 2014 First issue I have had and it is probably my own fault - I assumed that I could use Dynon updates, but should have only used FD updates. Now I am waiting longer because the wife of the software guy in Germany had a baby - if I have to wait, that's a pretty good reason. Link to comment Share on other sites More sharing options...

I had no problem after he gave me the unlock and download programs. Link to comment Share on other sites More sharing options...
Doug G. Posted March 27, 2014 Author Report Share Posted March 27, 2014 I used the unlock, and thought it had worked well until I started and then found the oil pressure indicator Xed out. I believe Dave Armando is usually the one that handles these things for FDUSA, and he had to go to his counterpart in Germany to get the specific configuration files for my units and sensors.
