In any engine the fuel  is nonuniformly distributed among cylinders,
i.e. fuel/air ratio is  different for each cylinder.  There are many
gadgets on the market claiming  improvement of the fuel distribution,
but I did not see these solutions used in production cars. In addition
some of these gadgets have  propellers rotating at ~60,000 rpm and
destruction of such a rotary gadget equals destruction of the engine,
since remains would be sucked into the engine.

Problem like that must be important in racing cars, and I guess that
many people looked at these issues. Is anybody  aware of a SAFE and
WORKING solution assuring equalization of mixture in different
cylinders? Is any of existing market gadgets any good?

Thank you,

Cylinders? We have no stinking cylinders. I have been after
Tracy for years to monitor the EGT and adjust the injectors
accordingly.

With the engine management computer that I plan on using, the injectors can
be adjusted to equalize the mixtures between rotors. I'm sure most
management computers would have this feature. I would think you would need
two oxygen sensors fitted to do these adjustments correctly. You could
remove them once the adjustments have been made. I have Tracy's EC2 but have
decided to replace it due to the user friendly tunability of other
computers. Just my two cents !!

What kind of computer are you using Michael? Tracy's computer does not use the
O2 sensor as O2 sensor are contaminated by 100LL aviation fuel.
Sometimes that is all you can get on a cross country flight.

I agree with you on the user friendly part. I am thinking of the
Mega Squirt because I know how to program it to do what I want
it to do. Mainly data acquisition.
