If you have 1 x Ems ground wire going to a good airframe ground then that will work.

A bit of clarity here. - the pressure sensor grounds, fuel flow, map sensor etc should be connected to the ground wires ( there are several of them) that are available out of the EMS module - the Oil Temp sensor body uses the engine case as a ground, there is no separate ground wire for it. all...

The best grounding method is to connect the sensor ground to 1 of the EMS module grounds - if you run out of grounds there then just join into 1 of them. you are using the Dynon (Kavlico) pressure sensors, correct?

Bill, I hear you however to expand on my point - this is the first time I’ve heard of this type of request so I’d suggest it would be a low priority ‘enhancement’ considering most of us would automatically check the Txpdr settings as well as comm frequencies. I too have missed checking the Txpdr...

Akash - the default K Factor is 68000, as per the Install Manual - afaik there is now minimum/maximum K, it all has to do with each individual installed FF unit & variations of its install. For most GA 4/6 cylinder engines you can probably expect to see the calibrated K factor be in the 50000 -...

It's one of those things - if you want full automation then I wonder what flying is about for those people, having checklists is part of the 'fun' & discipline - next thing is someone will want a parachute & a Dynon widget advising it has indeed been deployed - get over it !

BTW - no resister on the P-Mag lead ;)

Make sure the PPR (Pulse Per Revolution) is set at 2.

Ok, so your ADSB IN is working & not related to Txpdr. Can you post a screen shot of the Txpdr setup menu please, it would be most helpful ? Are you able to select the transponder using the MENU button at bottom of the screen ?

Agree, & if you did mess with it then I’d suggest the ‘fixed price’ repair most likely will not apply -could be expensive territory. I know of a situation where the G company would not even touch the unit or replace a memory battery for the GNS 480 - due to that the owner searched the internet...

He has only 1 I believe, it’s a legacy TT unit. Maybe he wants to display the VOR/ILS on the Dynon HSI instead of a separate HSI/CDI? Also something to do with the rate of Arinc data = slower for TT than most other Arinc equipment ? We really need more info from the OP.

I have one 10" screen & always wish for 2 however not possible in my panel - 2 x 7" screens just doesn't work for me.

A minus number eg -99 indicates a disconnect somewhere & maybe at the D25 end - when installing the thermocouples/wires I usually Remove the backshell & the blackheatshrink near it Carefully bend the harness to the shape needed when it's installed so the pins do not retract back from the fully...

My musings - is to maybe make up a 'rig' using a calibrated gauge & the MLH sensor, inject ~5 volts into the sensor power (connect the ground of course) & measure the output volts at the particular psi for say the 'green' range, you could also work out other 'range' points. Then set up your...

Email is the best/quickest option IMO.

OK - try this Honeywell MLH02KPSB06A = 0 - 2000 psi. you'll find a data sheet. There are 6 output options & 1 is 1-5volt - I'm going to try 1 on a Glasair in the next 2-3 months.;)

Although you have a 0-5 volt output is the sensor you have rated for 0-2000psi ?

Q1- Did you read the manual ? Q2- If yes & you couldn’t find the answer then we’ll try to help. Q3 - also if yes, & don’t comprehend then some of us will help where we can. A = it’s on page 5-11 in the Pilots User manual - please read it first, you may learn other things about the equipment you...

Did you bother to contact Dynon Support ? That’s always a good course of action.

Not sure what Dynon did in relation to the internals however I guess they have just disabled that usb cable input on new units after a particular serial number.
