What is the UBG-16?
The Ultimate Bar Graph is simply that - the Ultimate. No other bar graph in the industry comes
close to offering the options available for the UBG-16.
The UBG-16 arrives complete with pilot-programmable redlines for alerting pilots of engine
troubles, data recording for flight information reviews, in-flight engine
diagnostics information, differential and shock cooling alarms, hands-free leaning assistance,
long-term normalized mode, completely scalable EGT bars, and an array of functions available to
monitor. With the UBG-16 installed in your aircraft, you will have up-to-date information about
your engine at all times.
The UBG-16 comes with 16 customizable inputs. These inputs are capable of accepting the live data
output from EI's function modules. The wide variety of available function modules allows you to
keep an eye on all critical engine parameters. Choose between RPM, Manifold Pressure, Gyro Vacuum,
Volts, Amps, Oil Pressure, Fuel Pressure and Fuel Flow.
The UBG-16 comes complete with programmable alarms for each individual input channel. This means
pilots have the capability to set unique upper and lower alarms for each cylinder. The ability to
individually set redlines for your EGT's and CHT's is absolutely critical, as some engines have
cylinders with substantially different operating ranges from one another. Just because
cylinder number 4 might have a redline of 1350 does not mean Cylinder 1 has the same redline. Other
manufactures claim otherwise, because their instruments do not have this ability to set individual
On top of the already impressive individual redline programmability, the UBG-16 comes complete with
a CHT shock-cooling limit, and an EGT differential limit. Shock cooling will alert you if your
cylinders exceed a cooling rate that could result in thermal shock. The EGT differential alarm will
keep an eye out for rogue EGT's that may be an indication of a larger problem occurring in your
With the UBG-16's full suite of alarms, you will be alerted to most problems that can occur within
your engine, whether they be due to ignition, fuel mixture or compression. If your engine is not
giving you the performance it once did, if temperatures are not within the operating ranges you're
used to, or if limits are being violated, our technically adept staff will offer their assistance
when you are diagnosing what is occurring in your engine. Or, use our
Pilot's Diagnostics Manual
to study the art of troubleshooting on your own. Either way, we're here to help you.
