The Engine Data Management 700 and Engine Data Management 800 systems are some of the most advanced and accurate piston engine-monitoring instruments on the market. Using the latest microprocessor technology, the EDM will monitor up to twenty-four critical parameters in your engine, four times a second, with a linearized thermocouple accuracy of better than 0.1 percent or 2F.

Think of the EDM as your personal flight engineer. It's always there, working in the background, constantly watching over your engine while you concentrate on flying the aircraft. You can make an entire flight without ever pushing a button, if you so choose. Yet your EDM will be monitoring your engine parameters three times a second and will warn you instantly if any parameter exceeds the programmed limit.

Leaning is accomplished quickly and automatically using the LeanFind™ procedure. With the EDM it is now possible to have substantially more diagnostic information available to you in a timely and usable manner.

The EDM collects data and displays it for you in a useful way. You use the EDM to monitor engine temperatures and voltages, adjust the fuel/air mixture, and diagnose engine malfunctions.

The EDM 700 displays temperature digitally and in analog format. The EGT as displayed is based on probes located near the exhaust outlet for each cylinder and the TIT probe, if installed, is adjacent to the turbo charger. These probes are not necessarily collocated with the primary probes therefore; EDM 700 may not indicate the same as the aircraft primary instruments. The analog display is an electronic bar graph (vertical columns, one per cylinder) of EGT & TIT temperatures presented as a percentage of 1650F. Below the vertical columns the specific value for EGT and CHT are displayed digitally. The dot over the column indicates which cylinder's digital information is presently displayed. The missing bars at the base of the columns indicates the hottest and coldest Cylinder Head temperature trend. During Lean Find mode the leanest cylinder is displayed along with the fuel flow (optional) at that time. Depressing the LF and STEP button simultaneously brings up the adjustable scan rate function, OAT in oC or oF.

The EDM 800 instrument has all the advanced functions of the EDM 700, but incorporates some new features like % Horse Power and Manifold Pressure. There are new easy readable digits located at the top of the EDM display which continuously show the percentage of horsepower being used and can also display your RPM. Now you can be sure that you are within the horsepower limits of your engine, and in IFR conditions, this can be quite a task. The EDM 800 comes standard with Fuel Flow (201B or 231 Transducer is included), CHT (Probes included), EGT (Probes included), RPM (sensor included), MAP (Sensor included), OAT (Probe included), Flight Data Memory (can store up to 25 hrs. of engine data), EzPlot (download software), data cable and a RS232 INTERFACE connection to connect to any GPS navigation system. In addition a useful options such as TIT, Oil Temp, CRB, CDT and IAT are available for your engine.

There are no field adjustments and or calibration requirements for the EDM-series instrument after initial installation. ICA is not required. Maintenance of nonfunctioning or malfunctioning components is limited to removal and replacement of JPI factory supplied new or repaired components as described in the troubleshooting section of the installation instructions.

With the EDM acting as a flight engineer, you can enjoy improved fuel economy, reduced maintenance costs, and extended engine life. JPI is a leader in precision engine performance monitoring, and their expertise is built into the EDM 700/800.
