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.
