Required Order Form Think of your EDM-930 as your personal flight engineer. Always there, working in the background, constantly watching over your engine while you concentrate on flying the aircraft. Your EDM-930 will be monitoring your engine conditions four times per second and will warn you instantly if any measurement exceeds the programmed limit. Analog Display Bar Graphs Section Display - Oil temperature
The Normalize view permits rapid visualization of EGT trends, rather than a percentage of red line. The missing segment in the column represents the cylinder head temperature. Above each column is a number corresponding to the engine cylinder number. The rightmost column displays turbine inlet temperature. Beneath the bar graph is the alphanumeric display. A single index dot above one column indicates which cylinder is being displayed on this numerical display. When the index dot is beneath a cylinder number, 1 through 6, the digital display shows the EGT on the left four digits and the CHT on the right three digits. Two other derived measurements are shown in this display: The difference between the hottest and coolest exhaust gas temperatures. EGT EGT is shown on the first four or six Scanner bar graph columns. These are labeled 1 through 4 or 1 through 6 above the columns. The lower limit of the graph range represents half of the TIT alarm red line (default is 825°F) and the top of the range represents alarm red line (default 1650°F). The numerical value of the EGT is shown on the left side of the digital display for each cylinder when there is a dot under one of the cylinder numbers above the column—cylinder 2 in this example. There are two views: Normalize view levels the EGT columns and increases the sensitivity of the Scanner bar graph columns to 10° per segment. To enter the Normalize view, hold the LeanFind button for three seconds. The NRM icon will be displayed above the Scanner section. Hold the LeanFind button for three seconds to return to the Percentage view. CHT TIT |
As the mixture is leaned, EGT rises to a peak temperature, and then drops as the mixture is further leaned. Peak power occurs at a mixture using more fuel than at peak EGT. Best economy occurs at peak EGT. Accurate leaning yields optimal engine temperatures. By being able to precisely adjust the mixture, your engine can produce either the best fuel economy or maximum power, whichever you choose. |

So how do I use the Lean Find Mode?
Upon reaching cruise configuration, you can use the LeanFind mode to identify the first cylinder to reach peak EGT. Note that this is the leanest cylinder, not necessarily the hottest cylinder. You begin the leaning process by pre-leaning the mixture to about 50 degrees below the estimated peak on any one of the cylinders. For example, let’s say that you have determined that 1350 is the pre-lean value for your aircraft. Now wait about 30 seconds for temperatures to stabilize. You can enter the LeanFind mode by simply tapping the LeanFind button. You will then see the exhaust gas temperature of the hottest cylinder on the left display. Now you slowly lean the mixture at a rate of about 5 degrees per second. When there is a 15° rise in EGT, the Lean Find will become active, indicated by the flashing cylinder number of the hottest cylinder. If you have the fuel flow option, the fuel flow rate will be shown on the right display. Stop leaning when the column begins flashing. You will see PEAK EGT on the display, followed by the value of the exhaust gas temperature of the first cylinder to peak.. In most cases you will now be on the lean side of peak by about 10 degrees. While the column is flashing, slowly enrich the mixture. The temperature will increase, returning to peak. Stop enriching at the desired exhaust gas temperature, usually peak to 20 degrees rich of peak for best economy. |

I have been running a 930 in my Debonair for a few years now and love the size and functionality of the unit. The ability to use data driven diagnostics is outstanding.. This was the driving factor around my whole panel build.
Installed a couple EI units before, decided on JPI this time. Wish I hadnt. Seem like good units, but manual isnt as clear as EI and you need to buy many more parts you wont know about until you install and ask JPI questions. Example is you need two one amp fuses and holders on the shunt lines, which dont come with the unit. Its tough to know what all you need before hand unless youve installed a couple before. My next install will be an EI.

The only difference between the EDM 900 and the EDM 930 is that the EDM 930 has a larger display. Other than that, they are essentially the same.
The screen has a panel cutout size of 5.5" X 4.7".
The memory size is 100 hrs which can be transferred via USB drive.
Yes, fuel flow and CHT/EGT are included. The different versions are for the amount of fuel tanks in your system. Everything required for installation is included.
AML has been added to our webpage. Please download and review it there.
Per the manufacturer: It is recommended to use the new probes included with the kit.
You will need to use the new JPI probes that are included in the EDM package.
No, JPI does not offer an upgrade from 830 to 930.
