Introduction 1.1 Features: 1.2 Overview of the MVP Screens: 1.3 System Hardware: 1.4 SELECT Knob and Button Operation: 1.5 Display Dimming: 1.6 Cleaning the Screen: 3 1.
1.1 Features: The MVP-50P is a state-of-the-art Glass Panel Engine Monitor with in-flight data that provides most of the engine and system instruments found in an aircraft panel. Each of the instruments displayed on the MVP’s Main Engine Screen provides features not found in most multifunctional displays or traditional gauges. Aircraft panels equipped with individual instruments require a pilot to scan and interpret a multitude of gauges spread across an entire panel.
Screen goes into a red or yellow operating range, the appropriate annunciator will blink, the appropriate external warning light will blink and an appropriate voice warning will be played (experimental only). In this way the pilot is immediately alerted of a potential problem and should view the appropriate screen for further information. Setup and Control Screens (see section 5.
The MVP hardware consists of the following three groups of components: A. Probes, Transducers and Extension Cables – These components are used to measure pressures, temperatures, fuel flow, volts, amps, fuel levels and many other engine and aircraft system functions. The analog signals produced by the transducers and probes are routed through the Extension Cables to various EDC inputs. B. EDC (Engine Data Converter) – The EDC converts the analog signals from the probes and transducers to a digital format.
1.5 Display Dimming: The MVP provides two methods of controlling the brightness of the TFT display. When the “Brightness Control” is set for “Auto Dimming,” the display will automatically dim as the ambient light reduces. The light sensor is located next to the USB port on the MVP front panel. When the “Brightness Control” is set for “External,” an external control pot can be used to control the brightness of the MVP display.

The Main Engine Screen provides the aircraft system and engine instruments you will view most frequently during a flight. There is important information published in the Important Notice section (found in the front of this manual) that must be read before operating this instrument. Please read the Important Notice section at this time. 2.1 Power-up Add Fuel Message: The MVP requires approximately 14 seconds to power-up.
2.3 RPM and Manifold Pressure: The RPM and M.P. instruments incorporate a digital readout and an analog arc. The color of the digital readout will reflect the current range in witch the function is operating (i.e., if the RPM is operating in the red, the digital readout will be red). L. Mag Out The digital display can be set to blink when the RPM or M.P. operating level reaches a yellow or red operating range. To stop the blinking, push any button, or rotate the SELECT knob.
2.5 Engine Analyzer: The Engine Analyzer Display has five operating modes: EGT/CHT, Normalized, Lean ROP, Lean LOP and Digital. The MVP’s current mode of operation is displayed in the top left portion of the Engine Analyzer Display. The SELECT knob may be used to change operating modes. 2.5.1 “EGT/CHT” Operating Mode: The vertical bars are arranged to show the EGT and CHT for each cylinder. The hottest EGT and CHT cylinders are designated by a small red “H” in the bottom portion of the appropriate bars.
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.
2.5.4 “Lean - LOP” Operating Mode: This operating mode was designed to assist the pilot in leaning the engine Lean-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. As you continue to lean, additional tattletale markers will be placed at the top of the appropriate bar as each cylinder reaches peak EGT.
2.7 “System” Annunciator: Between the RPM and M.P. instruments is a “System” annunciator. If any function on the System Screen goes into the red or yellow, the “System” annunciator on the Main Engine Screen will blink. In this way the pilot is alerted of a potential problem and should view the System Screen for further information. To stop the blinking, push any button, or rotate the SELECT knob.
Power-up Announcement: When the MVP is powered up and the Voice Alarm Control Panel switch is placed in the “ON” position, the MVP will announce, “Voice Annunciator enabled. Have a nice flight.” This announcement will be made only once, at the beginning of each flight. Acknowledging and Silencing an Alarm for One Minute: To acknowledge and silence an alarm, push the switch on the Voice Alarm Control Panel momentarily to the “ACK” (acknowledge) position.
System Screen 3.1 Trim Indicator (OEM and Experimental): 3.2 Flap Indicator (OEM and Experimental): 3.3 Gear Position and Unsafe Indicators: 3.4 Gear Up Warning (OEM and Experimental): 3.5 Engine and System Functions: 3.6 Main and System Annunciators: 19 3.
The System Screen is intended to display system functions and the configuration of the aircraft. This gives the pilot one location (i.e., one screen) to find all of the pertinent system functions and configuration information on the aircraft. Normally these functions would not need to be displayed continuously. The following features in the System Screen are provided: 3.
3.4 Gear Up Warning (OEM and Experimental): The MVP can provide a gear up voice warning if the following functions are monitored: Gear Position, Manifold Pressure and Airspeed. As you enter the pattern and reduce Manifold Pressure the aircraft’s Airspeed will start dropping. If the Manifold Pressure and Airspeed drop below a programmed level (set for your aircraft) and the Landing Gear is not down and locked, you will get a voice warning.

“K Factor Adjustment” Section: If after filling the fuel tanks you find an error in the fuel “Calc’d Used Since Fill up” field (as shown on the screen) when compared to the actual fuel used (as read off the fuel pump), you can manually or automatically adjust the K Factor. The K Factor is a measurement of the pulses per gallon that the flow transducer outputs.
4.4 “Fuel Management” Screen: The “Fuel Management” screen is divided into the following four sections: Fuel Level Data: This section displays the fuel levels measured in each of the tanks. The total fuel onboard is displayed at the bottom of this section. The accuracy is only as good as the fuel sensors and the calibration of the MVP to each tank. Fuel Flow Data: This section displays fuel data based on fuel flow and is calibrated with the K Factor. The following data is provided: F.
“Dist. Reserve:” Distance you can fly beyond your Way Point based on current Distance to Empty and Distance to Way Point. If the Time Reserve drops below 45 minutes, this value will be displayed in Yellow. If the Time Reserve drops below 30 minutes, this value will be displayed in Red. 4.5 “Timers” Screen: The “Timers” screen provides the following timers: “Up Timer:” An Up Timer is provided with a recurring alarm. If the alarm is set for 30 minutes, you will get an alarm every 30 minutes (i.e.
The Tach Timer records the total number of hours the engine is run above 1300 RPM. The Tach Timer may be set in the “Engine Data, GPS, Timers, etc. Setup” screen. To the right of the displayed Tach Time is the status of the timer. The Engine Hour Timer records the total number of hours the engine has run. The Engine Hours may be set in the “Engine Type, Ports, Timers, etc. Setup” screen. Changes in this screen are password protected.
What makes the MVP’s Checklists so powerful is the fact that they are interactive. Next to each item is a “check” box. The Select knob allows you to enter an “X” in the box next to each item, or remove an “X” from a box if one is already there. Putting an “X” into a box will move the arrow to the next box. You may choose to skip any item in the Checklist by simply rotating the Select knob past the item. The MVP will always remembers your last place in any Checklist.
Opening a New Flight Plan: A new Flight Plan may be opened in place of the one displayed by pushing the Menu button while viewing the Flight Plan to be replaced, rotating the Select knob to select the new Flight Plan and pressing the Select knob to select and display the new Flight Plan. Creating a Flight Plan: A custom Flight Plan may be created in Word, WordPad, Notepad or most any text editor. See “Creating a Checklist, Flight Plan or General Information File” in the Appendix section of this manual.

The following describes the operation for each Setup and Control Screen. 5.
“Normalize EGT & CHT Now?”: Normalizing the EGT and CHT bar graph display will set all the EGT bars to the same level and all the CHT bars to the same level when operating the Bar Graph in the “Normalized” mode. Normalizing the display sets a baseline to compare future engine operation. A deviation from normal may indicate a developing engine problem. Before normalizing the display, insure that your engine is operating properly.
Flt #_Date X.csv # = Flight Number (same number stored in the Flight Log, Max Log and Min Log) Date = The date of the flight (example: 11-04-06). X = Flight Status (p = power on, engine off. r = engine running, no flight. f = flight timer started.) .csv = File Extension. Example: Flt17_11-04-05f.csv This section allows you to write 2, 5, 10, etc. or all the recorded flight data to the USB stick for review and/or evaluation. Flight data files will be stored in the “data” directory on the USB data stick.
5.3 “Voice and Display Controls” Screen: This screen allows you to control and/or set the following warning and display functions. For a voice to be heard, the MVP must be connected to the aircraft’s audio panel. “Voice Warning Control” Section (OEM and Experimental): “External Voice Switch is”: This field shows the current position (On or Off) of the External Voice Switch (this is a good troubleshooting tool). “Volume Level”: This field allows you to set the volume level for the voice warnings.
5.5 “System Configuration Screens Menu:” The System Configuration Screens Menu allows the installer access a number of setup and configuration screens. A description of the system configuration screens is provided in a following section of this manual.
System Configuration Screens 6.1 Password Protection: 6.1.1 Level #1 Password (Maintenance): 6.1.2 Level #2 Password (OEM): 6.2 System Configuration Screens Overview: 6.3 “USB Flight Data File Manager” Screen: 6.4 “USB Config and Software Program Manager” Screen: 6.5 “Change Password” Screen: 6.6 “Aircraft ID, Gear Warning and TAS Setup” Screen: 6.7 “Engine Data, Hour Meters and Flight Timers Setup” Screen: 6.8 “Serial Port Setup” Screen: 6.9 “EGT/CHT Bar Graph Limits and Color Setup” Screen: 6.
6.1 Password Protection: The MVP provides a number of screens for the pilot to use during flight, none of which require a password. It also provides many System Configuration Screens that are used to configure the MVP for a specific aircraft. Some of the aircraft functions (fuel level, flaps, trim, weight and balance, etc.) must be calibrated during installation and some must be set at the factory or by an OEM. The MVP provides two levels of passwords for configuring and calibrating the unit.
6.2 System Configuration Screens Overview: The System Configuration Screens provide access to setup and calibration data. By accessing this data you can properly set up the MVP to work with your aircraft. It is important you understand the operation of each screen and function before you change any data. If you do not have the knowledge to properly change an item, seek help. All changes must be verified that they provide proper MVP operation.
“Write Files to USB Data Stick” Section: “Write All Checklists and Text Files”: This command writes all the Checklists, Flight Plans and General Information to the USB Data Stick. All of the files will have a “.txt” extension and will be stored in the following directories on the USB Data Stick: Checklists ------- “checklists” directory. Flight Plans ----- “flight_plans” directory.
The “Retrieve ALL Backup Config Files” command reads all the stored configuration data on the USB Data Stick. If the configuration data was NOT stored to the USB Data Stick by same MVP that is retrieving it, the command will fail and an appropriate message will be displayed. Each MVP system has the following unique calibration data that should not be shared with other MVP systems: A. Temp Comp Diode offset (this diode is located on the middle connector of the EDC). B. PT-30ABS, Manifold Pressure offset. C.
Once the MVP has been configured for your aircraft the password should be set to a unique number to limit access to the configuration data. Do not lose your password! Without the correct password you will not be able to access the configuration data. If you do lose your password, contact Electronics International Inc. for help in retrieving it. 6.6 “Aircraft ID, Gear Warning and TAS Setup” Screen: “Aircraft ID:” The aircraft ID shown here will be used in the header of the recorded data.
“Tach Time”: This field allows you to set the Tach Time for the engine. Tach Time should only be changed with the engine off. Tach Time is a measurement of the total time the engine has run above 1300 RPM. This is an FAA approved method developed by Electronics International and is used in its TSO’d primary R-1 RPM instrument. Tach Time should be used to determine when the engine has reached TBO. “Engine Hours”: This field allows you to set the Engine Hours.
If the MVP cannot find a valid GPS signal, the Port 2 Receive Status field will switch (every six seconds) between “Trying 9600” and “Trying 4800.” If the MVP cannot find a valid GPS signal or the MVP is not connected to a GPS, the Port 2 Receive field should be set to “Disabled.” The Tx port will not transmit when the Receive Port is “Trying.” “Port 2 TX Format (Out)”: This field sets the format of the transmitted signal on Port 2 output.
6.9 “EGT/CHT Bar Graph Limits and Color Setup” Screen: This screen allows you to program up to five color ranges for each EGT and CHT cylinder. Every cylinder on an engine has its own unique operating temperatures. By setting EGT and CHT limits for each cylinder based on the engines unique operating temperatures, you improve the MVP’s ability to help detect problems early. “Function”: This field allows you to select which function (EGT or CHT) is to be programmed.
3. To detect a cylinder operating abnormally hot, you may want to set a red color range for each cylinder From approximately 30°F above peak EGT To a temperature well above any normal reading (approx. 2000°F). Note: Blue, orange and pink colors should not be used as one of the EGT color ranges. Set the CHT color ranges for each cylinder as follows: 1. Set a green color range From 0°F To the maximum CHT limit for your engine. 2.
6.10 “Weight & Balance Setup” Screen: The data in this screen configures the “Weight and Balance” screen (found in the “Flight Data Screens Menu” section of this manual) for your aircraft. It is imperative that the correct CG limit data is set up in this screen. CG data can be found in your aircraft’s POH. The data used in this screen is CG Limit Data (not moment data). The four graph points define the chart used in the “Weight and Balance” screen.
The tanks must be calibrated with the wings level and the aircraft set for level flight pitch. Start with the tanks empty. “Fuel Tank”: This field selects the fuel tank to be calibrated. You can switch between tanks any time during the calibration cycle. Note: The tanks must be calibrated in US gallons. However, fuel levels may be displayed in other units by changing the “Display Units” field in the “3. Redlines, Limits and Color Setup” screen.
“100% Max Power (Continuous at standard sea level)” Section: Enter the engine data requested in this section from your POH or published performance chart for your engine. Note: The actual Manifold Pressure at sea level will be slightly lower than Barometric Pressure due to induction loss. “Cruise Horsepower (65% to 75%)” Section: From your engine’s performance chart, select an RPM, MP and Altitude at which you normally fly that produces between 65% and 75% horsepower.
“Powered By”: The device that provides the Flap signal is normally a control pot. This control pot can be powered by the aircraft bus (preferred) or the by the EDC. If the control pot is powered by the aircraft bus, the MVP must do a ratio metric calculation to insure the flap readings do not change when the bus voltage changes. “2. Set the maximum Display values below.” “Max Upper (or Right) Value:” Enter the maximum up or right value. This would be “0” degrees for flaps.
Screen #2: This screen allows you to select a Main Engine Screen location on which the Function will be displayed. Screen #3: This screen allows you to select a System Screen location on which the Function will be displayed. Screen #4: This screen allows you to set the display units, operating range, limits and color ranges for each Function. Screen #5: This screen is for advanced use only and allows you to change the probe calibration data for any Function. 6.17 “1.
6.18 “2. Function to Main Screen Mapping” Screen: This screen allows you to customize the Main Engine Screen by mapping a function into any one of the four blue center instrument locations or any one of the horizontal strip or digital gauges located on the right side of the screen. Also, annunciators (displayed by an on/off light) may be mapped to any of the digital gauge locations.
“Displayed Operating Range (From__To__):” These fields allow you to set the operating range of the Arc or Horizontal Strip Gauges. Set the “From” and “To” fields approximately 10% below and above the maximum less minimum operating range. This allows room for the red limit area to show up on the gauge. “Color Range 1 to 5:” Each color used to set the various ranges of operation have a priority. The priority, starting from the lowest to highest, is White, Green, Blue, Orange, Pink, Yellow and Red.
“Probe:” This field displays the Probe assigned to the EDC Input selected above. “Raw Input Value:” This field displays the value of the uncalibrated signal measured on the EDC Input selected above. This value is transmitted to the MVP from the EDC. “Processed Value:” This field displays the value of the calibrated signal measured on the EDC Input selected above. The Raw Input Value is calibrated by the calibration parameters listed below.
“Snap to zero below:” If the Interim Value drops below the value set in this field, the Interim Value will be set to zero. “Proportional to Bus:” If the probe assigned to the EDC Input (selected above) is powered by the aircraft bus, the readings may change as the bus voltage changes. By selecting “Yes” in this field the MVP will perform a ratio metric calculation with respect to the bus voltage. This will eliminate reading changes due to bus voltage variations. Most E.I.
