Aircraft Engine Equipment We Recommend for Optimal Performance

Unlocking Efficiency, Reliability, and Longevity with Key Investments.

If you’re seeking to improve your aircraft’s performance and extend its lifespan, making wise investments in specific aircraft engine equipment can have a substantial impact. This blog post sheds light on three integral components: Engine Monitor Units, GAMIjector® fuel injectors, and a GPS-coupled Fuel Totaliser.

Why Investing in These Aircraft Engine Equipment Makes Sense

When you own an aircraft, your main concerns should be its efficiency, reliability, and longevity. We firmly believe that the right equipment can make a huge difference in these areas. If your aircraft is powered by Continental Motors or Lycoming, equipping it with our recommended aircraft engine equipment can enhance safety and efficiency. If your GAMI spread exceeds 1.0 GPH, it’s time to consider installing GAMIjector® fuel injectors.

Let’s explore each equipment in detail and how it can enhance your flying experience.

The Power of Engine Monitor Units

Engine monitor units are crucial for engine condition monitoring, aiding in engine operations, and troubleshooting.

Engine Condition Monitoring with Engine Monitor Units

Your engine’s data is a treasure trove of insights about its condition. With the help of your engine monitor unit, you can download and analyse this data for a better understanding. Making this task even simpler is SavvyAviation, who can analyse your engine monitor data and keep you informed about your engine condition with regular Report Cards and Trend Reports, ensuring the health of your engine’s exhaust valves. We highly recommend to install an engine monitor unit early in your aircraft ownership journey and to enroll in SavvyAnalysisPro for engine condition monitoring. 

Enhancing Engine Operations with Engine Monitor Units

Engine monitor units are indispensable for streamlining engine operations. By allowing you to see and record essential engine parameters during different flight phases, and set alarms for specific engine parameters, these units help increase your control over the aircraft.

An integral benefit of engine monitor units is their utility in conducting in-flight test procedures. Their recording function becomes invaluable as it enables post-flight data review, allowing for continuous improvement and troubleshooting. Furthermore, engine monitor units play a significant role in aircraft engine leaning, particularly when monitoring parameters like cylinder head temperature (CHT) and fuel flow.

Troubleshooting Made Easy with Engine Monitor Units

The data from these units can help diagnose problems such as advanced magnetos timing, clogged fuel injector nozzles, misadjusted fuel flow, and exhaust valve failures, essentially providing a health report for your aircraft engine before a problem becomes apparent.

Choosing the Right Engine Monitor Unit

Several brands offer engine monitor units, and the most suitable ones support data recording, temperature gauges for each cylinder, and fuel flow indication. Brands we recommend include Electronics International Inc., Insight Avionics, J.P. Instruments (JPI), and RS/Stock Flight Systems (Rotax). Other good options include Advanced Flight Systems, Vertical Power, AvMap Avionics System, Dynon, Dynon Certified, EFII Systems, Garmin, GRT Avionics (Grand Rapids), and MGL Avionics.

Maximising Efficiency with GAMIjector® Fuel Injectors

Operating your aircraft lean-of-peak (LOP) during cruise flight is more efficient and can extend your engine’s life. To operate LOP effectively, you need even mixture distribution among all cylinders, and GAMIjector® fuel injectors can help achieve this when your GAMI spread is large.

Carbureted Engines

For carburettor engines, your options may be limited to checking for an induction leak. However, sometimes, using carburettor heat (if equipped) and slightly closing the throttle valve—just enough to register on the manifold pressure (MAP) gauges—can atomise the fuel better, leading to a more evenly distributed mixture in the intake manifold.

Fuel-Injected Engines

In contrast, for fuel-injected engines, you have more control over a large GAMI spread. Installing GAMIjector® or TurboGAMIjector® fuel injectors will optimise your GAMI spread, improving your aircraft engine’s performance and capabilities significantly.

The Advantages of a GPS-Coupled Fuel Totaliser

A GPS-coupled fuel totaliser is a fantastic addition to your aircraft instrumentation, especially for fuel-critical missions. These devices aid in real-time decision-making about fuel consumption and planning. By adjusting your power setting and leaning during flight, you can ensure you arrive at your destination with your planned alternative fuel. Though they may not be required for all flights, they provide valuable situational awareness and planning capabilities.


Stepping up to incorporate advanced aircraft engine equipment like engine monitor units, GAMIjector® fuel injectors, and GPS-coupled fuel totalisers is more than an upgrade. It’s an investment in your aircraft’s performance, efficiency, and longevity.

The Vital Role of Engine Monitor Units

Our extensive exploration of these tools has highlighted how instrumental they can be. Engine monitor units provide essential insights into the health of your aircraft engine, detecting issues before they become serious problems. They’re a pivotal part of troubleshooting procedures, helping diagnose conditions like advanced magnetos timing, clogged fuel injector nozzles, misadjusted fuel flow, and exhaust valve failures.

Enhancing Efficiency with GAMIjector® Fuel Injectors

GAMIjector® fuel injectors represent another significant piece of the puzzle. These innovative injectors facilitate lean-of-peak operations, which not only enhances your engine’s efficiency but also extends its lifespan. By ensuring an even mixture distribution, they optimise the fuel-to-air ratio across all cylinders.

Heightened Awareness with GPS-Coupled Fuel Totalisers

Finally, GPS-coupled fuel totalisers enhance your planning and situational awareness during fuel-critical missions. They keep you well-informed about your fuel state, enabling necessary adjustments to ensure a safe and efficient flight.

The Rewards of Investment

By integrating these tools into your aircraft, you’re not only improving its operational capabilities and safety, but also saving on maintenance and fuel costs. In essence, these investments pay off by themselves over time. The enhanced performance and savings you’ll gain make these aircraft engine equipment not just recommended, but essential for all aircraft operators. Secure your peace of mind, your pocket, and the longevity of your aircraft with these equipment today.
