2020年11月15日 · In Layman’s terms, the N249 is a valve solenoid that is connected to the intake vacuum source to the back of the diverter valve (DV) and it controls the boost signal to the DV telling it when to open. Essentially it is a part that is there …

2005年4月8日 · PROs: By removing N249 valve, you can prevent this bad habit of the ECU, and by removing N249 valve, you are removing an approximately 2mm narrow bottle neck restriction (ID of the N249 valve) in the line to the DV, which will result in a somewhat faster DV response.

2008年4月1日 · On AWD/AWW/AWP engines the N249 valve has three connections : One going to the DV, one to the intake manifold for reference, and one to the vacuum reservoir (And the electrical connection of course.) I don't understand why your N249 is tied in to the charge pipe before the throttle body?

2011年7月15日 · Removing the N249 allows you to run a nice clean thick line to the intake manifold, thereby allowing a stronger boost and vacuum source to pull the diverter valve open faster, or push it down more readily. Removing the N249 removes the ECU's ability to dump boost in an emergency situation.
