Fixed timing - fixed mixture <
Yes, with electronics management (Injection), is possible to change the setting of the two things above.
In car/motorcycles competion this start some year ago (15 apx).
Now this technology is available in standard car/motorcycles engines.
Since 3/4 years ago, new system are available (I mean you can purchase it!) in competition car/motorcycles, while until few year ago, this was available only on factory car/motorcycles: Now, is possible setting you engine (timing and mixture) not only in a fixed way, but in a different way range per range, just connecting you PC with dedicated software to the engine.
F.I: If you are in a track, you can set different timing and mixture gear x gear / corner track x corner track, so you can have best help from your engine, driving easier and faster.
You can understood that this can work very well also in an aviation engines.
Try to think that your engine will change timing and mixture altitude x altitude, kind of “air” x kind of air.
This mean that your engine will improve their performance, giving it to you at any moment during a fly, without you must to take care of it.
Best power, best performance, best fuel flow. Do you like it?
This basically is the FADEC system Lyc and Continental are working on.
Honestly, I do not understand why it took so long time to become available, because it is already developed, and that is available from many years no more only in expensive car, but also in a “Honda Civic”!.
I do not understand why it should cost the amount Continental is rumored will be! Just for to prepare ourself to spend more we would to spend.
Magneti Marelli, Bosh and many other company developing and producing this system from many years ago for car-industry.
System is working weel, fully reliable year after year and with only one system per engine (no double as for aviation engines)Lyc and Tex-Cont choiced to develop this system with their own new company. This will increase their costs (and the system costs), the time for to be ready, a lot.
Customer will pay.
The opposite luckily Cirrus did and doing.
