Avionics LRU Installs and Programming

Avionics Install and Programming

Now that the wings are on time to install the Pitot

luckily I was smart enough to run the wires and tube long enough so everything pulls through the pitot mast.

Running the wire for the OAT.

Pinning the OAT

All set!

Screws have a little lock tight on them and the pito tube is installed! Making progress feels so good!

Securing the service loops.

I installed the Pitot tube inboard of the tie down so I didn't have to worry about it interfering with the tie down ropes. But this cause a new issue to make sure I wasn't interfering with the push rods. Little bending of the pitot and AOA tubes and the routing worked great.

Installed my hidden starter switch power.

Right now just with velcro until im sure I want it here.

The pilot stick has having a loose wiring issue so i cut and repinned the harness.

Pins installed.

Programming the G3X indications.

Section 53 ELT

 RV14 Build August 21

ELT

Purchased the ELT kit from Vans. Registered it with NOAA.

The install was relatively straight forward. Instead of riveting the beeper to the VS I attached it to the top of the ELT with hook and loop velcro and a zip tie for good measure. The cable was about 12" short to reach the location in the panel I had planned so moving the beeper here allowed for a shorter wire run.

Installing the tester in the panel.

There isn't much material on the faceplate but I did countersink it just because I liked the way it looks. Hopefully it doesn't crack in time.

FWF Routing Engine Sensors & Pmag timing

RV14 Build May & June 21

Emag wiring and FWF

Getting the CHT wired in, had to test it lol!

All the CHT are in. I used my heat gun to test that they are wired to the correct cylinder. All good!

We have manifold pressure! 

Another 14 was having trouble with fluctuating manifold pressure readings and I read that Garmin recommends using a PS-8G so i went ahead and installed one right at the base of the sensor

After the restrictor I install the elbow and pressure line.

The Oil pressure and Fuel pressure sensors are installed. Just have to trim the zip ties once I commit to this final placement.

Routing the CHT wires and securing them

Secuting the #1 CHT and EGT wires.

Keeping the rear EGT wires long enough to reach the front cylinders to help with future troubleshooting.

The EGT holes are already drilled you just have to open them up a little more. The plans have you use a #30 i think, but it wasn't enough to I let the bit wobble in the hole a little to make it slightly bigger. This gave me a nice tight fit for the EGT sensor. The sensor cables are looped to prevent fluids from wicking up the line.

Right side all wired and routed.

Left side all wired and routed.

Ive never used one, but I started to worry about needing an alternate static source so Im going to install this valve.

The valve really wants to spring open to I purchased a red flip up guard to help keep it closed

The switch is mounted behind the G3X screen on the subpanel.

Man buss with wire protectors.

The automotive wire harnesses are fatter than standard lycoming. I used a reamer to open up the mounting baffle pass throughs.

Tight and snug fit now.

Programming the PMAGS using the EICAD program. For a IO-390 you need to find version 4 to set the timing but use version 3 to read it and make sure it took. There is a glitch in the system for 4 when you use a negative value for advance shift it will display it as 12.6.

My initial settings are to fire at 20BTDC all the time with no advance to help with CHT temps and diagnosis if there is a problem I know its not advanced timing causing it. You can see on this version 4 the advance shift is displayed at 12.6 even though I put it in at -7.

Using the back to the spinner ring gear to set TDC

Line it up with the case.

Emag wiring and FWF

Figuring out how to route the ignition harnesses so they weren't bundles and had a good length.Next several photos just showes how I did it. I purchased some ignition harness wire separators, then ended up being a little large so 1 wrap of rescue tape on the harness clamped everything well.

You have to use a step drill to enlarge the hole of the cushion clamps. These are #7s. I need #8 for 1 since the alternate are cable will pass through it as well.

The harness are a fatter than standard magnetos, so the baffle pass through dont work as they are. TBD on how to fix that.

More routing.

Finally cutting and wiring in the Pmags.

Fairly straight forward. I did end up tinning the leads to help them not frey when installed.

I removed this cushion clamp to get the wires through, not necessary the wires will slide through so save yourself the trouble here.

Before I installed the second pmag I fogged the motor as best I could with ACF50.

Wiring up the second PMAG.

Running the ignition cables on this side.

After re reading the PMAG plans I realized my ground wire was too small so Im replacing this with 14awg.

Connecting the PMAG manifold pressure.

Installing CHT 2 and the fuel flow transducer and connecting to the wirring.
