The question was not specific as to fuel. Or number of cylinders. I beleive there are singles in FAI compititions. Pattern maybe.

Well if I don't head out to work, it will be glow/singles for me!

Me too! Been running Amsoil 100:1 for years now and I yet still have to see an issue with any of my engines!

Re: The never ending engine thread, East-West

Fuel injection ain't quit as nice as you think. It does come with it's own headaches Wieghts of engines will go up. Plus side if u like laptops u can really fine tune a engine

Myself i would like to see some super charged engines come out to play with

That and if you change the prop load(change props) you must re-map the fuel tables.

Not quite true anymore, I personally use Autronic EMS on my race car, the investment in Dyno time to tune all the load cells makes it possible to put on Different Tires and Diameters (similar to props) and hit the appropriate load areas.

I've tuned EMS from Pectel, Autronic, ViPec etc.

Airplane engines are actually slightly simpler to tune on EMS, because the load variences the engine will see is closer to 2D tuning than, speed density type of air metering can be used for temperature / altitude compensation, and have the ECU modify parameters based on EGT for Timing and AR Correction if you want to throw in an AF sensor, you can have finer corrections, since you're doing that, throw in a knock sensor too... LOL

The new ECU's (CAnbus) in cars, actually have an AFR table that can be easily modified through open source tools. ( openecu.org )

Not as difficult to have EFI, but you will need to put an electric fuel pump in the plane, that's open loop that feeds fuel at a constant pressure through an (FPR) to the fuel injector. It's not worth it in my opinion, the simplicity of carburated engines for model use has yielded reliability and efficiency, that is hard to beat.

Throwing in EFI in a model engine will just complicate it, but then again, if your enjoyment in the hobby is playing with EFI, that's a different story.

Re: The never ending engine thread, East-West

Can they get a system like that small enough yet? The system on the DA170 I was told is load specific.

Yes they can, it doesn't take much, speed density sensors come in all shapes and sizes, knock sensors are just simple microphones aka transducers, and O2 sensors (AFR's) are already made that small. Electronics are also made now that is small enough for RC planes, fuel pumps can be fabricated along with fuel pressure regulators.
