It should work just fine in a rotary, so long as fuel flow in both housings
is about the same. The troubled engine feel is when one housing is
performing less well than the other. So when leaning one housing has peaked
before or after the other, or has reached well lean of peak before the
other.
It should be possible to imitate the same effect using computer control. It would require that the computer control injectors individually, and that it has input from EGTs or a wideband O2 sensor for each rotor. The concept is trivial...the implementation somewhat less so.
EC2/3 has this capability built in. Mode 4 (&5 on 20B) controls this function. Running far LOP smoothly does depend on mixtures being well ballanced. If well ballanced, the engine does not get rough when turning the mixture control way down. When you reach the limit, the engine should just suddenly stop with almost no warning (other than the declining rpm as you lean).
