UBG-16 Operating Modes

Overview of 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.

Normal Mode

Overview

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.

Bar Graph

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.

Digital Display

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.

Displayed Functions

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.

Programming

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.

Profile Mode

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.

Normalized Mode

Overview

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.

Lean Mode

Overview

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.

LOP

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.

ROP

For pilots wishing to operate their engines on the Rich side of peak, the UBG-16 is the perfect 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.
