Aircraft model engine DLE-170 with our www.flame-power.com "Powered by Speeduino" injection kit. 17hp 5kg including 832 gramms moulinette to measure power. 172 grammes add our fuel pump. New PCB box will be much smaller.
Our Alpha-n implementation take into account air density and temperature. We as well enrich fuel mixture if cylinder head overheat.alpha-n is available
Has anyone mentioned you have to buy industrial Capacitors or your dielectric plies will lose calibration over many on off cycles?
We use ceramic high end capacitors for customer who ask for, it add 50USD.Electrolytic capacitors
============================Can this forum come up with a reasonable EFI for small engines? So software, ardino or appropriate, and common source the bits throttle body, injector, airmass flow sensor, temp, etc. for small engines. It seems a better alternative to have a fuel injection system that compensates for density altitude automatically as a normal function than trying to cob up a carburetor that kinda' works. Maybe the files for an EFI could be filed in a manner for easy access.
Ecotrons: Experienced people who have tried to get a reliable Ecotrons system working have found the hardware to be crummy and the software/tuning to be opaque and difficult. Do you know of any Ecotrons systems that are flying?============================
Ecotrons or Mega Squirt.
True. And a person could, in this way, in theory, try out every one of the hundreds of combinations of relevant sensor anomalies. They could also download the software and even modify it to better meet aircraft needs. But, they can't buy or build their own hardware (to better meet aviation requirements) without risking a lawsuit. And the software is
Its very big difference to use Arduino or only its processor atmega2560consumer grade Arduino

MegaSquirt: One version (MicroSquirt) is used by Aeromomentum. The hardware is not cheap and the software is quite large and complicated (with plenty of "should be explored" what-ifs that apply to aircraft but not cars). For some airplane applications, maybe it can be made to work well, but I'd want to understand its response to every type of errant sensor data (no data, erratic data, failed at high reading, failed on reading, etc) for every sensor.
To weed through all of that and to understand the hardware and software code of MegaSquirt could be quite an undertaking. It is 'fat' with all types of features (VVT, sequential ignition, closed loop operation, etc) that I wouldn't want or need in my planned aircraft installation. It's fine for "tuners' who want to experiment and can pull over if things stop working. I'm not sure it is great for an airborne system that must be bulletproof.
