Hello to all.
Well I'm writing this in the hope that someone who understands the induction circuit might read it and be able to explain how it works.
My engine has the twin doser, with one hose coming from the intercooler outlet and the second one coming from a bypass Y piece which leads to the intercooler inlet side.
Both butterflies have what look to be the same actuators, however only the side which comes from the intercooler outlet side has an electronic and vacuum connection, which weans this butterfly is controlled by the ECU. The bypass butterfly has neither connection, meaning it has no control and is static, the butterfly is sprung in the open position, meaning that the engine is always drawing in air that has not passed through the intercooler. Now isn't that defeating the object??
Obviously there is a reason why it is like this. If anyone knows how this system works please could they explain.
