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.

With the circuit you provided you want to install a diode.  With the door switch open you are basically feeding the EMS input with 12V through the relay coil.  The diode will provide isolation / very high impedance from this. With the diode installed the EMS signal will "Pull-up" to the 5 volts...

This is the reply I got from Seattle Avionics's Steve Podradchik: "Hi Kurt. Yes we just became aware of this and have already fixed it for the next release. We did test the Dynon support before release but a change was made after the test that, unexpectedly, caused the problem. Love to get you...

I normally would not use this forum for this problem but in case I am not the only Skyview driver that is using Seattle Fly-Q. I would recommend that you DO NOT UPDATE TO VERSION 3.0 I updated to FLY Q EFB 3.0 and flew with it for the 1st time. It will lock up or abort immediately when it...

Thank you all for the information! Ill give them a try. Kurt

Has anyone had any luck with any Android App (Samsung tablet) that will connect and display traffic and weather from the SV? I am currently using the NAVIATOR app but I am unable to get any traffic or weather via wi-fi connection. I have e-mailed Naviator a couple times and they have never...

Either have a VP-X fault or a Custom Engine parameter is out of range. You may be able to get more info from your alert log. Check the SV Pilot User Guide, last section.

Select the "Front side" course with the CRS knob. This is one of the functions of the LH SV knob "CRS" . Select CRS with the LH knob and rotate until correct course is on the arrow head. You set the inbound course after you select and load the desired approach. Press the OBS button on 430 to...

I dont know for sure but I know that DPSK in a communication system means Differential Phase Shift Keying. This is a modulation technique that is used in digital transmitters / receivers. I suspect if you are getting this error you will have to contact DYNON and most likely send it back for...
