MVP-50P Overview

The MVP-50P is now TSO’d and STC’d! If you plan on ordering the STC’d version of the MVP-50P, be sure to fill out the Redlines and Limits worksheet for the package you order.

What is the MVP-50P?

Without question, the MVP-50P is the industry’s finest engine analyzer and systems monitor, hands down. Electronics International has redefined what an engine analyzer should be with the full color, glass-paneled, completely customizable MVP-50P. The MVP-50 allows pilots to accurately monitor dozens of engine and system parameters, program redline limits, setup custom inputs, create interactive checklists, store general flight information, build flight plans, record and review pertinent data from every flight, and so much more. The MVP has been designed with the same thoughtful engineering that goes into every EI product, so even though the MVP-50P is by far the most powerful system in the industry, it is sure to be one of the easiest systems to use in your cockpit.


Programmable over-temp limits provide pilots with immediate alerts whenever critical function parameters are exceeded during flight. Onboard data-recording gives pilots the capability to review entire flight histories for any flight. A complete bar graph gives critical engine information during flight, including leaning assistance, temperature differentials, audible and visual limit alerts. The System Screen is dedicated to aircraft systems, including flaps, trim and rudder, as well as whatever other functions you want to view. Customizable checklists visually inform you which steps have and have not been completed in each checklist. General Information Screens and Flight Plan Screens can be customized to store critical flight information, allowing you to create a “virtual cockpit,” free of the pieces of paper pilots regularly have to juggle to stay on top of in-flight operations.

The RPM is displayed in large, bright, crisp digits as well as in a 270 degree graphic arc, so you can simultaneously monitor RPM at a glance and with precision accuracy. Wires from the MVP-50P harness connect to the back of the aircraft ignition switch and pick up the signals from the magnetos. The MVP-50 provides lightening quick RPM response while maintaining rock solid stability.

Manifold Pressure

Like the RPM, the Manifold Pressure is displayed in large, bright, crisp digits as well as in a 270 degree graphic arc. You will be able to dial in your Manifold Pressure with precision when flying with the MVP-50

Outside Air Temp

The MVP-50P simultaneously displays Outside Air Temperature in Celcius and Fahrenheit, meaning you don’t have to do in flight conversions or switch between the two. Ice Zone warnings can be set to alert you when temperatures reach ranges within which ice can form

Engine Temperatures

EGT and CHT are always shown for each cylinder, whether in Bar Graph or Digital Mode. Temperatures have a stable, one degree resolution for accurate leaning and engine diagnostics. Both EGT and CHT differentials, as well as the hottest cylinders, are always displayed for quick reference.

Fuel Flow

The main screen constantly displays the current fuel flow, accurate to .1 gph. Proprietary algorithms allow rapid response to engine adjustments without irritating, jumpy readings.

Fuel Levels

Up to four fuel levels at a time may be monitored and displayed on the Main Screen at one time.

Electrical System

The precise resolution of .1 volts and .1 amps allows you to accurately monitor and manage the load on your aircraft electrical system and the health of your battery.


Select from Up Timers, Down Timers, Flight Time and Clocks.

The Bar Graph

The MVP-50P comes complete with a full engine analyzer. The MVP-50P bar graph displays EGT & CHT, has programmable redlines for each cylinder, displays temperature differentials, assists with leaning for ROP and LOP operations, and has an easliy resettable Normalized Mode with long-term memory for engine trend analysis.

Redlines & Operating Range
Regardless of the parameter you monitor with the MVP-50P, the operating ranges are completely programmable. The MVP-50 will alert you via visual and/or audible alarms when a parameter exceeds the programmed limits.

Choose Your Functions

Several different functions are available, including Gyro Vacuum, Flaps, Hydraulic Pressure, Pressure Altitude, Airspeed, virtually any temp or pressure, plus more! Or, add an additional voltage or amps to monitor a secondary bus. The MVP-50 even allows you to create and name your own functions. The options are nearly limitless.




The System Screen provides pilots with tremendous flexibility by providing a whole other page to monitor important functions. Any function, from trim, flaps and rudder to baggage door relays can be monitored on this page


If you have a sensor with an output, the MVP-50P can monitor it. Simply program the MVP-50P to accept the input, and name the input whatever you want. The options are virtually endless.


Each parameter monitored by the MVP-50P can be programmed with ranges and limits. If the parameter exceeds a programmed limit, the MVP-50P will alert you immediately, either via an audible alarm in your headset, a bright external LED, a flashing number on the MVP-50P or a combination of the three.

Main Functions

Regardless of what you choose to monitor on the System Screen, all of the main functions from the Main Screen are still shown on the righthand side bar. Every displayed Main Screen Function is depicted graphically and digitally for easy reference and precision.




The MVP-50 boasts a fully functional bar graph, complete with ROP and LOP leaning modes, a Normalized Mode, state-of-the-art “peak markers” and separate programmable limits for each cylinder’s CHT and EGT to alert the pilot of any engine trouble

ROP Mode

The Rich-of-Peak mode on the MVP-50 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-50 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 occuring within your engine.

Peak Markers

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