Two MVP-50P’s provide the ultimate solution for a twin-engine aircraft. The moment an engine problem arises with one of the engines the digital display for the out-of-limit function will blink in the color of its current operating range. In addition, an external caution or warning light will blink giving the pilot the earliest possible indication of an issue. All the information needed for the engine in question is in a single display. You do not have to hunt all over the instrument panel to find the data necessary to make a decision.

The accuracy of the digital display for each engine parameter (M.P., RPM, Fuel Flow, etc.) allows the pilot to balance each engine’s performance and synchronize the props with ease. Check out our website and see some of the twin-engine installations and the 14 additional screens available for the MVP-50P.


Main Screen

The Main Screen

At the top of the MVP-50P’s main screen is the Manifold Pressure and RPM gauges. From left to right, they are aligned with the aircraft’s throttle and prop controls. These gauges provide both analog and digital displays. The digital display provides accuracy and allows the pilot to detect small trends. The analog display provides field-of-vision, allowing the pilot to determine a function’s position in its operating range.

Along the right side of the Main Screen are six analog/digital gauges, followed by three Digital-only gauges. These gauges display Fuel Flow, Fuel Pressure, Oil Pressure, Oil Temperature, Volts and Amps. Optional gauges are Fuel Level, Vacuum, TIT, Hydraulic Pressure, G-Meter, Carbon Monoxide, Cabin Pressure and Altitude, Airspeed and a number of other gauges and annunciators.

In the left lower portion of the Main Screen is the most sophisticated EGT/CHT engine analyzer on the planet. The bars in blue show the EGTs and the bars in green show the CHTs. The pilot-programmable maximum and minimum ranges for both EGTs and CHTs are displayed and can be set to match any engine’s operation. You can learn more about the Bar Graph in the section at the bottom of this page.

The blue section between the instrument groups provides 8 support functions. This section can be configured to display Horsepower, OAT, Up Timer, Down Timer, Local Time, Zulu Time, and a number of other gauges and annunciators.
One of the most valuable features of the MVP-50P is its ability to alert the pilot the moment an engine or aircraft system function reaches a caution or warning area of operation. The color of the digital display represents the area of operation. If all the engine and aircraft parameters are operating within acceptable ranges, all the digits in the digital displays will be shown in green. If a function drops into a warning or caution operating range, the digital display will be shown in red or yellow, as appropriate. In addition, the digits will blink and an external caution or warning light will also blink. Some MVP systems can be equipped with a voice warning system.

The MVP-50P was designed to reduce the need to constantly scan and interpret engine instruments. The moment a problem occurs the pilot is notified. This allows the pilot to deal with a problem long before engine damage occurs, giving the pilot options he otherwise may not have.

Bar Graph


DigitalLEAN - LOP

The MVP-50P comes standard with a state-of-the-art, full-color bar graph which assists with ROP/LOP leaning. Additionally, the bar graph has both “normalized” and digital readout screens. No other bar graph in the industry comes close to providing the number of options the MVP-50P offers.

ROP Mode

The Rich-of-Peak mode on the MVP-50P informs the pilot when the first cylinder peaks, as well as how many degrees below peak the engine is operating.

LOP Mode

For Lean-of-Peak Operations, the MVP-50P informs the pilot as each cylinder peaks, at what temp each peaks, and how far from peak each is. For quick reference, every cylinder’s peak information is constantly displayed and “tattletale bars” are shown above each cylinder, indicating where each cylinder peaked the last time the engine was leaned.

Normalized Mode

The Bar Graph can easily be “Normalized,” creating a baseline from which to monitor in- flight engine temperature changes. When Normalized, all of the bars start off at the same height. If any cylinder’s column is not the same height as the others, than that cylinder’s Exhaust Gas Temperature has changed in relation to the other cylinders. These changes can be critical indicators to problems occurring within your engine.

Peak Markers

While other monitors don’t maintain your engine’s leaning history, The MVP-50P’s Bar Graph keeps track of exactly where the cylinders peaked during each leaning process. When leaning, the MVP-50P displays a peak marker indicating where each cylinder peaked during the last leaning process, providing visual assistance to pilots.

Other Screens

Other Screens

In addition to the “Main Screen”, the MVP-50P offers a “System Screen”, “Fuel Management Screen”, “General Info Screen” and a multitude of additional screens. These additional screens give the MVP-50P flexibility not found in other engine instruments. Simply push the “SCRN” or “Screen” button found on the front of the display to cycle between the MVP-50P’s multiple different screens. At any time you can push the “Exit” button to quickly return to the main screen. Any time the main screen is not being displayed you will have annunciators at the right hand side of the screen to warn you if a primary function goes into caution or warning.

Name: William Archer
Model: PA46-310P
The unit is the most user friendly engine monitor that I’ve seen. It was just the right size for my panel.
Name: Robert Old
Model: A-1C-180
The MVP-50P is Bright and Accurate, and just plain looks great in the airplane.
Name: William Blackburn
Model: Cessna-182
EI had the most positive reports of customer satisfaction in the blogs I follow and review. Turns out the reports were quite accurate. We particularly appreciate the succinct display and the timers page and logical layout of important engine info.
Name: Otto Knottnerus
Model: Cessna 182Q
LOVE the display + information it gives me – the warning lights are a great feature.
I really like the layout of the system and how it helps in the leaning process.Aviation Consumer had a great review of the product and that helped me in the purchasing process.
Name: Bob Howell
Model: Murphy Moose
This is my second MVP-50 so obviously I am happy with the product.Your customer service is excellent and the sales staff were familiar with the instrument. I have tried JPI’s 740 but their instrument has numerous flaws. JPI’s company attitude and poor customer service is a marked contract to EI.
Name: John Gill
Model: Cessna TU 206F
The MVP-50P is very intuit to operate and has greatly improved my ability to do fuel management and careful engine operation. I also liked that the data download did not require proprietary software. I choose the unit because of the good reviews and positive review in consumer aviation.
Name: Rick Pearson
Model: PA-46 310-P
I liked the additional features the MVP offers such as the Checklists,TAS- Calculation and System Screen.

Name: Seth Martin
Model: Cessna 177RG

Everything has turned out very well.So far the MVP-50 seems to be a great instrument. Very intuitive and easy to use, while still being completely customizable.It had more customization over the JPI 930. We like the ability to set caution rages for various parameters. We also liked the visual display better than JPI.
Name: George Andraos

Model: Bonanza F33A

Tech support is excellent, few minor issues was resolved quickly.Both Daniel and Tyler were very responsive and helpful. The main reason I choose the MVP-50P was because of the customer support and customer service.
Name: Frank Wilson
Model: PA46-310P
We liked the number of sensors possible, the remote EDC mounting (We have a pressurized airplane) and the checklists feature. The higher sample rate and increased memory storage were also key features for us.
