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.

  • Reduced pilot workload. 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 safely 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 older types of 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.

  • Strong ignition output. With a powerful coil output and a duration of more than 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 increase the ignition output during cranking for easier starting.

  • 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. The wiring harnesses are manufactured using the highest quality components and proven techniques to greatly increase the durability of the harness assemblies, using strain-relieved and flame-resistant wiring.

  • 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.
