Yes, I know,  (i mis-spoke about KE vs K lambda), but why not modify the
control pressure regulatro to do the control pressure modulation, by
using say for example a stepper motor with a "screw shaft" ( a shaft that
looks like a scre for linear drive) that is able to change the pressure on
the control pressure diaphragm, thus actively controlling the mixture.
ITs a hell of a lot simpler than the "electrohydraulic actuator" designed
by bosch, and a hell of a lot cheaper than a 800 dollar new distributor.
Just an idea for those who might want a little feedback from their older
pre KE and K Lambda systems..

	A stepper motor, and a driver is about 20 dollars, an
electrohydraulic fuel distrib is over $800.   Hell you could be cheap and
use a Pot on the dash to adjust the mix.
