1) It is possible to tap off one of the injector channel to power the WI valve (HSV). There is however a small problem of the accuracy of original pulse affected by loading and decrease of inductance on a parallel connected coil. It means one of the injector will inject a slightly different quanity from the others.
So we develop the 2d system that only draws about 1mA to the injector circuit. You can just buy the FIA2 amplifier and HSV if you have other pump organized - you will loose the fault diagnostic function. It mirrors fuel injetcor's duty cycle. 2) We have had people leaving the WI constantly on by mistake and was surprised that it doesn't use that much more water. Richard
