Electronic Fuel Injection and Ignition
for Aircraft Engines
* High Energy Ignition Kits - NOW AVAILABLE *
Finally, a modern engine managment system for your Lycoming engine. We've all heard the various complaints about Lycoming engines, lead fouling, hard starting, mag failures, etc. Contrary to the negative impression these discussions may make, the heart of your aircraft engine package, the engine itself, is a pretty good and reliable piece of equipment. Most Lycoming issues and complaints generally stem from the antiquated components bolted to the engine. Mags are unreliable, have very low spark energy and fixed ignition timing, mechanical fuel injection and carburetors are marginal in quality of fuel distribution and rely upon the pilot to act as the fuel computer causing lead fouling, hard starting, and fuel waste.
The question has been asked many times - "Why can't we just put modern electronic engine controls on the Lycoming and cure all the bad habits". Well, the answer [now] is - you can!
The EFII system is a complete modern electronic engine management system for your Lycoming engine. EFII stands for 'Electronic Fuel Injection and Ignition'. We have developed a modular system that allows you to choose your entry point into the modern age of aircraft engines.
Our line of ignition and fuel injection products allows you to start with the basics if you like with a single mag replacement high energy ignition system. You can add components at any time to step up to the dual mag replacement ingition system or you can go all the way with the full electronic fuel injection and ignition by simply adding the additional components. No other aircraft electronics company can offer the quality of components and engineering or the flexible upgrade migration path for your project. We have been designing performance ignition systems and vehicle electronic products for the automotive and motorcycle industry for more than 20 years. Finally, you can enjoy the benefits of these technologies in your experimental aircraft.
Some of the benefits of the EFII system are:
- You will be ready for the day when 100LL avgas is no longer available.
The EFII system is flexible and programmable and can be run with any gasoline or ethanol fuel.
- A MUCH better ignition system than magnetos!
The EFII high energy ignition is the highest energy aircraft ignition available!
Our ignition has enough energy to jump a one inch spark gap in free air and will light your
plugs for a full 15 degrees of engine rotation at 2500rpm. No moving parts means no wearing parts.
Your EFII ignition will give you years of trouble free service. Having a proper ignition timing
curve will help to unlock the true horsepower potential of your engine.
- Hard starts are a thing of the past!
The EFII system will deliver the proper fuel and a fat spark under all starting conditions.
Your batteries and starter motor will last much longer and you won't get stuck with a flooded
engine.
- Automatic mixture control at all altitudes.
With the EFII fuel injection system, the pilot is no longer the fuel computer. You will always have
the correct amount of fuel evenly and automatically distributed to each cylinder at all power
settings and altitudes. This will save fuel, reduce lead fouling, reduce engine wear, and makes
flying more fun!
