What is the EI 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 redlines.
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 engine.
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.
UBG-16 Operating Modes
The UBG-16 has three distinctive Operating Modes, each with unique features and benefits. There is also one "Mode within a Mode," the "Profile Mode," which provides information on the engine's fuel-to-air mixture profiling.
The Normal Mode is where the UBG-16 displays digital and graphical information about EGT's, as well as digital information about other monitored functions. The Normal Mode is where all pilot-programming is performed, and where the somewhat hidden "Profile Mode" can be found.
The whole point of owning a Bar Graph instrument is, arguably, the bar graph feature. The bar graph provides a quick reference to pilots regarding the temperature status of each, individual cylinder.
In addition to the quick reference offered by the bar graph, the UBG-16 displays a precision digital reading for each monitored function. This way, pilots can keep a close eye on exactly what their engine is up to.
Each Cylinder's EGT's and CHT's are displayed in the Normal Mode, in both graphical format and in Electronics International's stable, one degree (Fahrenheit) resolution. Other functions are available, including many pressures, temperatures and other functions. See the "Accessories " page of the UBG-16 for a complete list of available functions.
All pilot programming will occur in the Normal Mode, from the face of the instrument. Do not be intimidated by the powerful features found in the UBG-16; the programming could not be simpler. Electronics International's engineers have taken great care to ensure the UBG-16 has the same straightforward, common sense approach to programming that all of our products are famous for.
The Profile Mode is a feature unique to the UBG-16. After leaning your engine, check out the Profile Mode (within the Normal Mode, go to "Peak" and click the Mode switch one time to the left) to view your engine's fuel to air mixture profile. This is an excellent tool for people with Gamijectors installed, or for those wanting to balance their engines. The closer the bars are in the Profile Mode, the closer the fuel to air mixture between the cylinders.
The Normalized Mode gives pilots a visual indication of trends occuring within their engine. When the bar graph is "Normalized," all of the EGT bar graph columns are equalized in height. If, after normalizing the bars, any column is substantially different in height from any other column, then a change has occured within the engine, which may be an indicator of an engine problem.
Long Term Memory
Though some other manufacturers may claim to have long-term memory, the UBG-16 truly does. It does not simply remember the normalized status for one flight, only to reset again when you re-cylce the power or re-enter the Normalized Mode. Instead, the UBG-16 stores the Normalized information until you reset it. This allows you to monitor engine changes over the course of several flights, instead of just during one flight. You can choose to reset the information as many times and as often as you like, but it will not reset until you ask it to.
The UBG-16's Lean Mode gives hands-free assistance to pilots during the leaning process. The instrument provides critical leaning information for both Lean of Peak (LOP) and Rich of Peak (ROP) operations.
For those pilots wishing to operate their engines on the Lean side of peak, the UBG-16 is the perfect instrument. For every cylinder, the UBG-16 alerts pilots as each cylinder peaks, and displays the peak temperature for every cylinder. In addition, the UBG-16 displays how far from peak each cylinder is operating once they've peaked, so you don't have to do the math in your head. This kind of thorough, precise information allows pilots to pinpoint exactly where their cylinders are in relation to peak during the leaning process.
For pilots wishing to operate their engines on the Rich side of peak, the UBG-16 is the perfrect instrument. The UBG-16 alerts pilots when the first cylinder peaks, as well as its peak temperature. The instrument then displays precisely how far from peak the leanest cylinder is, so the pilot can dial in the exact distance from peak desired.
UBG-16 Data RecordingThe MUX-8A
Every UBG-16 package comes standard with the MUX-8A Data Recorder, for no additional charge. The MUX-8A receives information from the UBG-16 and stores each flight in a date and time stamped, comma-delimited format. The MUX-8A can be setup to record data every one minute, three minutes, six minutes, or it can be put it into the "Burst Mode" to record information as quickly as possible (usually every five to six seconds). Data files downloaded from the MUX-8A is compatible for viewing on EGView software, or can be easily viewed in a charting program such as Excel.
EGView is the de facto software for reviewing flight information in an easy, powerful format. This software automatically formats your MVP-50 data files, creating spreadsheets that seperate engine temperatures, pressures and other monitored functions into different graphs and colors.
: The UBG-16-Mem packages come with a serial output for data collection. If your computer does not have a DB-9 serial port, you will need to purchase a Keyspan Serial Port to USB Adaptor.
