Installation of JPI 830 and Gami's

[Bob]

This technical thread is dedicated to Mitch.

I have a appointment Tuesday to install a JPI 830 and also Gami injectors on my 1980 231 Mooney.   Yes these "toys" were purchased at Oshkosh.

I am doing an owner assist installation with my avionics installer.  My plan is to take some pics and share the details of the installation so anybody interested can become more familiar with engine monitors and their Mooney.  The installation is of the Complete EDM 830 unit plus TIT and CDT probes.  This will include, oil temp, oil press, fuel flow, OAT, EGT, CHT, TIT, CDT and RPM sensor.  In addition to the install, I have to relocate the Hobbs and Intercom controls to the right side of the panel.  Optional changes may include swaping the location of my 480 and the MX20 multifunction as well as getting rid of the loran.

A current panel picture is shown in my gallery.  The red circle is a warning light to slap me in the face to check the gauge.  The switch is to switch between screens on the 830.  All suggestions or tips are appreciated.

Would it be worth putting in a new PS Engineering audio panel instead of moving the intercom?

I hope you know I was kidding about all this.  I was away all weekend and only got fragmented views of MooneySpace during that time.  Seemed like everytime I did get a chance to look in, there was a new post about relief tubes.  I just thought it was fun to see so much talk about the subject. 

I love MooneySpace and all that goes on here.  In lieu of hanging out at the airport with other pilots, it's the next best place to just talk about Mooneys and airplanes. 

Bob, your panel looks great to me.  Yes, maybe the new PS intercom as Ron suggests.................fun!

[Bob]

Yes Ron, a new audio panel would be wise, but that is on my list for next year.  I do not want to get $maxed$ out.  This kept me from going all the way to the JPI 930.  I am trying to just do the 830 install and line everything up for step 2, while trying not to redo too much later.  After the 830 install, I have my annual coming up in a few months.  Then step #2 for the panel, will include a audio panel upgrade, remote mounted mode c transponder and a back-up gps.  I currently have a 196 on the yoke.  I would like to get rid of that and add a Aero, 696 or simular.  I am hopeing by next year they will have a larger Aero so I can panel mount it on the right side.  I will set-up the battery back-up gps for a traffic monitor, on always, so I won't have to flip thru the multifunction to see it.  Then in the event of total power failure, I can use it as a emergency gps.

As you see from the full, current, panel shot.  If I get rid of the Loran on the right, It will give me a lot of room for the Hobbs and intercom controls untill I redo the whole right side later.

Thanks for the feedback Ron!

Ditching the Loran and swapping places on the 480 and MX20 are both great ideas. Get rid of dead weight, free up room and make the back of you panel cleaner by chucking the Loran. The Arrow I used to fly had the same 480/MX20 combo as yours, but it had the big display on top and the 480 below. Not a huge difference, but I prefered this arrangement because I used the MX20 for primary navigation most of the time and liked having it closer to my line of sight. Down and to the right seems awkward to me. The swap shouldn't cost you hardly anything I wouldn't think.

Dave,

The 480 and MX20 swap will depend solely on the length of the harness.  If the existing harness has to be lengthened, I am going to pass for now.  My origional install was done back in 03 when the MX20 and 480 combo were new on the market.  The avionic guys realy did not know what to do with them at that point.  Now we all know that the Multifunction is more user friendly when on top.  This is why I flew the plane for 8 months before makeing any changes.  It is unbelievable how you evaluate a panel when you are all alone for a 4.5hr flight.

Well, I opened the box and am getting prepaired for the install in the morning.  JPI helps get things going in the proper direction by having everything in little bags with labels.  They also have a parts list for each bag.  It looks like they give you almost everything needed except shrink tube, plastic ties and fittings specific to your application.  I am very impressed overall except for one thing.  Any ideas?  See first picture.

My JPI unit was purchased from Gami along with the injectors.  Today I contacted Gami and requested that they overnight a JPI-830 for the 6 cylinder that I ordered and not the 4 cyl unit I received.  Gami took care of the small mistake promptly and JPI handled everything at a unbelievable customer service level.  JPI is a top noch operation!

Today was a great learning experience!  I basically installed most of the items on the engine while Matt, the avionics installer, took care of the panel dissembly and planning.  The EGT, TIT and CDT probes all installed by drilling a 1/8 hole and securing the probes with the supplied hose clamps.  The fuel flow and oil pressure installed with basic plumbing properties.  The oil temp probe screwed in.  The RPM sensor basically screws in to the mags, but is a very tight working environment.  Everything is very simple, but as we all know, takes longer than you would think.

As you see below Matt jumped in and went at it!  I learned that the ideal plan that I invisioned, sometimes is not possible or is just not financially wise.  I am able to swap the 480 and MX20 so the multifunction is on top.  But the intercom wires are too short to move to the right side of the panel without a lot of labor.  My only current option is to turn the intercom controls verticle to allow room for the 830.

In the morning Matt is going to re-install the trays and complete all the wireing at the panel.  I am going to run the engine wireing harness and connect all sensors and then top it off with a Gami installation.

If all goes well, we should be able to test the system in the afternoon.

Good Luck and be patient.

Will the JPI 830 serve as a FAA approved, TSO'd replacement for factory MP/RPM, Fuel Presure guages?  I've heard different answers from different folks.

[drpep]

i CHECKED WITH JPI REGARDING THIS POSSIBILITY BEFORE I INSTALLED MY 830. THE ANSWER WAS NO, YOU CANNOT REPLACE THE MP/RPM WITH THE JPI 830. WITH THE 900 YOU CAN. I AM NOT SURE ABOUT THE FUEL PRESSURE GUAGE

George,

The 830 does not have any primary functions as it is sold.  However you can add only 3 primary functions to the 830.  They are CHT, TIT and Oil Temp and cost $400 each.  This would be pointless since the TIT and CDT are both in one factory gauge and the CHT and Oil temp in most cases are also combined with others.  You can pay about $2000 more and get the 930.  The 930 is a primary replacement for all functions.  When I reviewed the idea, I determined that the panel space saved by getting rid of the factory gauges is lost by the size of the 930.  It didn't make any sense to me.  It would have also forced my Engine Monitor to go to the far right side of the panel.  Less user friendly and $2000 more, no thanks!

Jpi realy seems to be on the ball and has shown a history of offering existing customers with upgrades at fair price points.  I bet in the future, the primary upgrade for existing 830 customers may be offered.

Does anyone know if the outside air temp is primary required equiptment?

[Bob]

Today went very well.  Gami's are installed.  I need about another hour on the engine and 1/2 hour on the panel.  Then test and fine tune as needed, check for leaks, etc.

Not much to add today.  Basically just grunt work.  But boy was it great!

[drpep]

As far as I was told it is. The 830 I installed added oil temp, oil pressure, MAP  and RPM. I exchanged my JP1 700 with fuel flow for $1200 and added the 4 additional probes for a total of $950.
