Ive watched these valves, over the couple of months ive owned the car, and all i can see, is that the valves are closed, for a couple of minutes, during warm up, and then open from then onwards. So, all i can see these valves are used for, is for helping the cats, and the engine to warm up quicker ?. They are open all the time when the car is up to temp. So i dont really see the point of wiring them open, because they are always open anyway, when warm, regards, SIMON.
