I would agree with you except why does the GNS430W show different from SV by 28kts? All the data is from same source( Skyview) except the GPS course. Why does the GNS430W gps course and the GNC250XL GPS course differ from SV GPS course by 7 degrees? Before about 2 weeks ago the GNS430W and SV...

I have some additional info that makes me believe this is a Dynon GPS issue. Perhaps related to the GPS time missing (parsing issue) on older GPS250 pucks. When I view the GPS Course on the GNS430W or my GPS250XL they agree with each other but the Skyview GPS Course is different; to the right...

I noticed on my last two flights the Dynon Skyview wind speed is off by ~25 to 30 kts.  The wind direction is correct as I compare it to the D-100 and the GNS430W.  I used to see all 3 be reasonably close to each other with the GNS430W exact same as Skyview.  Does the GNS430W not get all the...

The ELT needs a NMEA formatted GPS signal. If any of the other outputs are set to NMEA you can double up the connection match the baud rate on the ELT settings. The ACK has jumpers for Rx rate. Or, depending on what other GPS navigator you have you can move the ELT to an unused port on it...

If the fuel flow drops when the boost pump is ON you are getting air into your fuel lines. Probably between the Electric pump and the engine driven pump. Check lines for tightness and fuel stains. It is possible to have air sucking in without fuel leaking out (no stain). Another possibility...

You can move or remove any of the displays (Map, PFD, and engine) to any position (L, C, or R).  No problem having the PFD portion on the RH side of display. I think it is 50/50 when you have only 2 panels open.

Dynon, I have a D100 set up as my standby flight display as it is totally independent of the skyview system. My D100 is installed in my Glasair on the Future Vision instrument panel. This panel has the inserts canted to favor the pilots viewing angle (about 10 degrees). See attached photo...

Rob, Based on your description the problem has to be bad connection on the alternator side of the shunt, the ANL 60 fuse/ holder, alternator itself, or field wiring / field circuit breaker. Check all the connections between these points. Just because the alternator has been replaced does not...

It may help if you tell what brand of alternator (external regulator?) and how the shunt is connected. Is it configured as an alternator load meter or a battery charge/ discharge indicator. I assume it is in a Vans RV7 ? But it sounds like something in the alternator circuit is intermittent...

I had the GPS HSI (magenta info block and needle) blank out on 4 occasion in quick repetition, each about 1~2 second long.  This lasted for about 20 seconds total.  It was VFR so I immediately downloaded the diagnostic file. The problem occurred on 12/31/2018 approximately 16:39 to 1645 Z. Hope...

I had issues with inaccurate fuel flow readings specifically when i flew longer, higher altitude flights, >9000 ft. I would notice fuel pressure fluctuating when I started my initial cruise and I turned OFF the boost pump. The fuel was being heated from the climb and due to the higher altitude...

I have loaded the new SV software 15.3.4 but still see my HSI needle and info block blank out for a second or so. (all magenta blanks out). Saw it yesterday on a short 1 hour flight. Even though the change notes say: Fixed: A bug that caused ARINC to occasionally drop out. I was hand flying...

Regarding the P-Mag tach signal it is coincident with the firing. The falling edge of tach is when the coil fires the plug. So, they both should be firing at the same time. Check your timing and check the manifold pressure connection. if one p-mag has a leak it will not advance as much...

The pins you use depends on the type of transducer you are using and the output it provides.  My UMA pressure transducer outputs a voltage.  It is powered by the aircraft power buss, not SV.  The best choice for me was the "Type C" input.  You should be able to use the Type A for most pressure...

Tim, It has been a while since I have added my pressure sensor but this is what I remember: Export your current USER files to usb stick and put them on your computer  The .SFG file is the sensor definition file.  Open this file with Windows notepad or any text editor. I added a hydraulic...

I have used the Electronics International EGT probes with excellent results. Over 1400 hours and no damaged probes on my Glasair w/ Lyc IO360. These are noticeably heaver / thicker than other companies. The only difference you may notice is they are slower to respond.

Bill, I agree with you 100%.  If the SV tach inputs can be split into 2 independent measurements and can accept an Input of 12KHz (9897 Hz + 10% + margin for worst case of N2 ) will be the easiest to accomplish.  This will also be the most accurate hands down. It starts to get complicated if you...

Check your setting of the PULS/REV R and L values as described in the Engine Information Section. Value depends on # of cyl's and type of ignition.

I see a few issues that most likely only Dynon will be able to answer : What is the maximum input frequency to the Tach inputs? Manual say max RPM displayed is 9,999RPM but you can scale to % to get around this. What is the max Pulses per Rev you can input in SV? you need 115 (N1) and 297...

Has anyone with 15.3.3 tried to upload their flight log data to Savvy? I tried several times and got an error on the "USER_LOG" file.
