It does, and it's a really tempting option for the money. But can you get a 'hardened' Arduino processor for it? The processors in the RWS controllers, and the Micro/Mega stuff, and (I assume) the same or similar processors as the automotive world, and they've been thrashed in pretty much every possible manner by the auto mfgrs to beat out potential failure modes due to the hostile environment they operate in.
Speeduino does all that
and costs $150
I'm going to use Megasquirt MS3 Ultimate on my
20B. I've been running a mega squirt in my Jeep for over 10
years. The unit has never failed me. It has a great user
interface, the tuning software runs on a stable Linux platform,
and allows me a view screen that is programmable with all my
custom parameters. It easily handles three rotor ignition with
split timing, staged fuel injection, multiple tables, multiple
oxygen sensors, and multiple map sensors. Other features include
fuel pump control, knock and detonation detection. This will
allow me as close to a FADEC experience as possible. The tuning
software will allow a number of custom inputs, including
multiple pressure and temperature readings. Recording is
continuous, and can be extracted via SD card, Bluetooth, or USB.
The current pricing for the ECU only is about $1,300, and a copy
of the tuning software is $80. A generic wiring harness is about
$200. Additional costs for the oxygen sensor and controller will
bring my total package up to about $2,000. Let me know if
you have any questions.
I am in the process of installing the fuetech as
well. I wanted to add that it also has a screen, visible in
sunlight, that is a complete engine monitor, expandable, fairy
useful, and data logging possible.
add those features and it becomes cheaper than
a EC2 + EM2

Have been flying with the fueltech for
possibly 8 years after my EMC caused problems. tracy was
able to fix, no problems, but due to time in freight to
the US and OZ I was down for 6 weeks. Did fiddle with
another local Oz version but was complicated. The local
rotary gurus put me onto the fueltech which is also
complicated as is designed for race cars / hotrods etc..
It does have a section especially for rotarys, possibly 3
pages but controls everything well. IN Oz at the time it
was dear at $2800 AUD but had and still has backup.
Controls spark, fuel, timing, turbo on a rotary. Then
there is about 70 pages of stuff you will not need in
aircraft, like gear change, burnouts, boost and whatever
else they use in drag racing. For me the big issue is
backup which these days in OZ is impossible to get in
anything.
