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.
