Dump Valves...?
I have an Audi A3 1.8T Sport 1999
I am looking to get a:
Blow Off Valve(BOV)whichmust be used with Bosch K-Jet injection, as being a closed system, any loss of air for which fuel has already been metered by the movement of the airflow sensor plate, will result in an over-rich condition and possible backfire. A CBV is found on many "OEM" original engine manufactured EFI turbo systems.
or
Compressor BypassValve (CBV) whichis suited to an EFI system that uses a MAP (manifold absolute pressure) sensor. As the MAP sensor source is inside the inlet manifold's plenum chamber, relieving air before this with a closed throttle butterfly (throttle lift-off) will not affect running.
THE QUESTION ISwhich Injection system have i got?
Thanks a million people!
