Yes I have heard of them as well as a half dozen others.

They don't give you what you want to know on the instrument
panel. They are also way more money than the PC solution.
The PC can store 64 Gig on just one USB stick. Not just 500K.
It can also log data every second.

Closed loop O2 control does not work with 100LL aviation
fuel. The lead contaminates the O2 sensor.

The fact of the matter is the modern $80 PC Intel Atom mother board is
ten times as powerful as the processor your likely to find in these
automotive ECU's. When you add the $90 Hytek you have a total of 3
processors all working together.

Here is the specs for the 2 rotor version.

Hi Paul!

Thanks for your hard work in this forum.

You are heading the right direction with the PC solution.

I was once close friends with Jim Munn, the owner of MOTEC USA in Huntington Beach CA. He provided the ECU to Mazda for the Le Mans winning 4 rotor car back in the early ninetys. (For marketing reasons, the manufacturers did not allow MOTEC to put their name on the race cars).
I am writing to address all those who keep bringing up these race car ecu units unnecessarily. Aircraft simply do not need what the MOTEC, or any of the other highly capable units for race/street performance cars can do. Even the lowly home built Mega Squirt is more than is needed. (I own two of those)
 Think about this folks, what Paul is doing with the PC solution is far superior to any of the automotive units. He will potentially be providing users with capability to interface all of the functions of the aircraft, directly on the instrument panel, not just the engine, or monitoring flap angle, airspeed, etc. But we would be able to use it to control everything, even flying the plane remotely, or with auto pilot operated from the PC board; just on one of these small fast PC board setups.
 Imagine getting into your craft, turning on the ignition, and looking at a 15" computer monitor that you built into your dash, and seeing hundreds of data streams on display, access to pinhole mini cameras mounted in you cowling, or anywhere else!

 This is transformative, it is revolutionary to the experimental home built industry. I truly hope some of you programmers join in with Paul to make it a reality.

Racing Beat sells and supports the Motec unit and it is a very good unit.
Price however is about $1,800.

Thanks Ed for your understanding on this issue. I might also point out
that there are some very sophisticated moving map programs out there
that will run on the same type of PC mother board and hardware. Some
show the terrain you are flying over in 3d  with all obstructions shown
so this is a monumental advantage in low visibility conditions.
