The EDM-800 instrument has all the advanced functions of the EDM-700, but incorporates some new features that can only be found on JPI products. No longer do pilots have to waste time looking up and guesstimating the present percentage of horsepower (HP).

There are new easy readable digits located at the top of the EDM display which continually show the percentage of horsepower being used, & can also display RPM. What is unique about this new feature is that it can also display HP over lean. HP can be displayed for either carbureted or injected engines, even if they are turbocharged. 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.

At the present time HP is only available on single engine 4 and 6 cylinder engines. The EDM800 calculates percent of horsepower in an Over lean condition. Lycoming & Contentinal horse power charts stop at peak EGT on the first cylinder to peak. Gami has developed a method of going over lean on all cylinders. When you are over lean, every ounce of fuel is burned & used to create horsepower and heat. Cooling is accomplished by excess air in the combustion chamber. JPI has developed an algorithm to calculate horsepower based on fuel consumption and other factors.

To obtain HP in this over lean condition you must have an EDM-800 engine analyzer with fuel flow, RPM, MAP, OAT, Memory & Gami tuned injectors. In addition to JPI's HP function, EDM800 also has a Memory Module that can store up to 25 hrs. of engine data, which can be downloaded to a laptop or palmtop PC. When using the memory function, all functions of the EDM will be recorded, including Fuel Flow & HP.
