 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.

 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.

 I wrote my first articles for Kitplanes on this subject back in 1988
 1989.

 Automatic position reporting could be helpful
 when pilot's hands and mind are full.

HEY PAUL!!!!!!

   I just felt saying THANKS A LOT FOR LETTING THE REST OF
TAG ALONG FOR A GREAT RIDE!!!!!! [YOU'RE THE MAN!]

Here are some pictures of my late 1980's glass cockpit in the C182
with a 8088 mother board. Updated the map every second written
in QB under DOS no less. I would use QB again and DOS if it
supported USB but it won't so Linux and C it is.

Here is the chassis picture. We got the FAA airport data base
off a 9 track tape. Ross Perot's old outfit called Electronic
Data Systems or EDS for short. EDS had a $100,000
a year contract with the FAA to maintain it on a IBM mainframe.
I called the FAA and offered to maintain it for free on a PC.
No takers :)

It had a lot of blank spaces so I zipped it and got
it down to fit on a 1.3 meg floppy. That is why the
floppy drive is in the chassis. Now a days a USB stick
will hold 64,000 times what a floppy can hold and is
a lot morer rugged and draws way less power.

The other pain in the
butt was the power supply. Now a days you can get PC
power supplies that will run off 12 Volts.
