the hottest and coldest EGTs and the hottest and coldest
CHTs. A differential limit may be set in the “EGT/CHT Bar
Graph Setup” screen. Information for setting these limits is
covered in section 5.1 of this manual.
Scan Mode: The Scan Mode automatically scans through all
of the cylinders. As it scans through the cylinders, the EGT and
CHT numeric values are displayed in the bottom portion of the
Engine Analyzer display. The scan rate can be set in the “EGT/
CHT Bar Graph Setup” screen. To navigate to the “EGT/CHT
Bar Graph Setup” screen start by viewing the Main Engine
Screen, push the Menu button and select the “EGT/CHT Bar Graph Setup” screen near the botton of
the page.
Hottest Mode: The Hottest Mode displays the hottest EGT and CHT in the digital display below the
bars.
2.5.2 “Normalized” Operating Mode: The Normalized Mode of
operation is an engine diagnostic tool that allows comparison of the
current EGTs and CHTs to a reference (past flight). By normalizing
the EGTs and CHTs the vertical bars are brought to the same level,
creating a reference baseline.
The EGT and CHT bars may be normalized (leveled) at any time by
pushing and holding the Select Knob for four seconds or by entering
the “EGT/CHT Bar Graph Setup” screen.
The offset data to level the bars is stored in MVP permanent memory.
The Normalized Mode allows changes that have occurred in the engine to be spotted easily. This makes it
possible to detect trends over several flights, days, weeks, and even years.
2.5.3 “Lean - ROP” Operating Mode: This operating mode was
designed to assist the pilot in leaning the engine Rich-of-Peak EGT.
As you lean, the EGT bars for all cylinders will rise. When the first
cylinder reaches peak EGT a tattletale marker will appear at the top of
that cylinder’s bar. The current EGT reading, Peak EGT reading and
the Temp Below Peak reading for the first cylinder to peak will be
displayed at the bottom of the Engine Analyzer Display. Another
cylinder may be selected (and its data displayed) at any time during the
leaning process.
Once the first cylinder reaches peak EGT, richen the mixture. The
data at the bottom (and top) of the display will indicate the number of
degrees at which your engine is operating rich of peak. This is exactly the information needed to properly
operate ROP.
