As you can see on the diagram, there is also an electrical valve between the manifold pressure output and the manifold pressure input of the WUR. In fact I installed this valve in order to allow me to return to original WUR setup. At beginning this was useful to discover the original behaviour of the CIS. ( and to make measurement with the datalogger) Now this valve stay closed all the time …I could simply cut the boost enrichment line but I prefer to keep it wired in case of problem. Unlike the famous adjustable WUR setup, this electrical valve is not triggered by an RPM switch (there is no need)

ELECTRICAL VALVE ( WUR line boost enabling / disabling )
Very impressive. I do have one question. Why disable the MAP sensor line to the stock WUR?
