Hello Gelf,
I am sure it is possible to do it. It is not easy for me to test the method machanically as it requires some intense flow calculation and then machine something out to do it - the flow through a irregular path of a solenoid is quite complicated.
It is simplier for me to alter the electrial signal of the MAF.

Surely you must be able to calculate a fixed diameter opening to weaken the mixture by a known percentage, which would be opened by a selonoid triggered by the WI circuitry ?
Say for example
5mm = 5%
7mm = 10%
9mm = 15% etc
