The UBG-16 provides
many excellent features to help you operate your engine on the rich side of peak
(ROP).
The UBG-16 makes it easy to lean your engine on the rich side of
peak EGT (ROP). Just place it in the “Lean” mode and start the leaning process.
The UBG-16 will display the cylinder that first reached peak EGT the last time
you leaned your engine, as well as the current EGT and CHT readings. The word
“LEAN” will appear below the bars, followed by the EGT reading for that cylinder
(see the picture below left).

During the leaning process, the UBG-16 will automatically display the first cylinder that reached peak EGT and its temperature (see middle picture above). By pushing the Mode switch to the left, the digital display will show the exact number of degrees the leanest cylinder is below peak EGT (see right picture above). You can now enrich the mixture to precisely lean the engine to any temperature you choose on the rich side of peak EGT (ROP). Quick, easy and precise.

Another method of leaning, unique to the
UBG-16, is to set the operating range of the bar graph display to match
the leaning range of your engine. If the bars are running close to the
bottom of the display (see left picture), a quick glance tells you that
your engine is running rich. If the bars are running close to the top of
the display (see right picture), a quick glance tells you that your
engine is running lean. |

Since the top bar was set to appear at peak EGT
for the leanest cylinder, it’s easy to see how much below peak that cylinder is
running. This means it won’t be necessary to find peak EGT each time you lean.
This method works great and can save time as long as the leanest cylinder peaks
close to the same EGT during each flight, which is usually the case.
On takeoff, look for all the bars to be close to the bottom of the display. When
climbing or during high altitude takeoffs, lean to keep the bars off the bottom
of the display. When leaning, keep the leanest cylinder’s bars just below the
top of the display (depending on how far rich of peak you want to run your
engine).
