Our UltraSky EMS has been developed to be the highest quality electronic engine management system available for high-performance Lycoming aircraft engines.

 

As of January 2017, we are currently only offering this system for installation on engine assemblies that we are producing, this gives us the ability to fully calibrate the system in one of our engine test cells prior to shipment.

 

 

 The UltraSky Electronic Engine Managment System (EMS) has been developed for use in high-performance Lycoming aircraft engines. Our system incorporates many unique features that increase the performance, safety, and longevity of the engine. Below is a listing of some of these features:

 

  • Complete calibration. The fuel and ignition tables are fully calibrated according to your engine configuration, airframe requirements, and intended use to provide the optimal settings during all engine operations and situations. This means that there is no trade-off between optimal high-power operation, efficient cruise, and smooth idle. Our system features multiple 3D maps to provide a complete calibration basis for each engine and it's particular application.

  • Reduced pilot workload. The move to electronic/automated engine management is driven by the desire to reduce the pilot's workload - especially in competition flight. Our system lets the pilot focus more on flying and less on managing the engine. From automatic adjustments based on altitude and temperature, to easier starts and the ability to comfortably fly at a reduced RPM on final, we have done our best to make flying easier and more enjoyable.

 

  • Stable ignition timing. Unlike magnetos that suffer from timing scatter due to both internal and external drive clearances, the electronic systems maintain accurate and consistent timing events throughout all RPM, temperature, load points, and transitions.

 

  • Timed electronic port fuel injection. Utilizing a dedicated fuel injector for each cylinder that is timed within the engine's power cycle, fueling is significantly more controlled than constant-flow mechanical fuel injection. This means that the proper amount of fuel is injected without waste. So not only is cylinder balance improved, but so is cycle consistency.  The increased consistency and accuracy in fueling allows us to safely extend the engine's margin with respect to power output - resulting in a safer, smoother, and more powerful engine assembly.

 

  •  Durable fuel rail assemblies. Our fuel injectors are supported by specially-designed fuel rails that are manufactured using our vacuum-brazing process to produce a durable and leak-free assembly.  Because we work with so many high-level competition aircraft where aerodynamics are highly scrutinized, we had to be sure that our rail assemblies remained as compact as possible in order not to interfere with tightly-cowled engines. 

 

  • Strong ignition output. With a powerful coil output and spark duration of >3ms, leaner fuel mixture settings can be maintained when in reduced-power (cruise) flight and during ground operation. The increased output also minimizes the chance of a misfire during high-power operation. Even further, we are able to specifically increase the ignition output during cranking for easier starting. All of this leads to a smoother, cleaner engine.

 

  • High-Flow Throttle Valve Assembly. We design, test, and manufacture our throttle assemblies in-house for proper fit and function - from pouring the raw castings to final machining and assembly - ours throttle valves are optimized for performance Lycoming installations.  These high-flow assemblies are significantly lighter and shorter than standard fuel servos for easy fitment.  A unique feature of our throttle housing is the tapered bore, this allows us to place the pivoting throttle plate in a larger diameter section so that it presents less restriction to airflow.

 

  • Enhanced engine safety. The system can automatically compensate for under/over-voltage situations, as well as when abnormally high or low ambient temperatures are encountered. The system also includes a rev-limit feature that will immediately reduce engine power in an emergency situation such as a propeller or governor failure.

 

  • Durable control, peripherals, and wiring. The passively-cooled control unit is designed to withstand substantial shock loads and is water resistant. Our harness assemblies are true works of art and set our system apart.  Those familiar with MS spec wiring will recognize the construction and high quality of components that we use in the manufacture of each harness.  Additionally, our harnesses feature a modular design for an easy and clean installation which also simplifies troubleshooting and replacement if the harness is damaged.

 

  • Simple data viewing and recording. Bluetooth integration with RealDash application for Android/IOS/Windows devices makes data analysis a simple task. You can easily save data recordings as a standard .csv file for analysis at home or upload to our data server for in-depth inspections. We can even remotely view your engine data in real-time from anywhere in the world (as long as the aircraft is within cellular or wifi network range).

 

  • A complete system. We strive to provide everything possible needed to install the system onto your engine. This includes completed harnesses, switches, installation hardware, filters, and more. According to your installation, you will add/modify the battery setup and fuel plumbing – which we provide thorough recommendations and instructions for.  Additionally, as with all of our products, we are happy to provide full support during installation and throughout the system's life cycle.
