The small valve/solenoid mounted on the os inner wing (on a classic) next to the boost solenoid, Made by Denso.

What is it and what should it do....?

 

MAP sensor?

 

Ahhhh would that explain why it's not connected when running an Autronics ecu.....?

 

yes you probably have a new map sensor that the autronics uses.

 

The vacuum pipe that was connected to this sensor from the inlet manifold now goes directly through the bulkhead, which i can only quess then goes straight to the ecu. Would the ecu have a built in map sensor....?

 

yes

 

Thank you very much.

 

Cheers RV, just got some more info on this and i'm told this could well be compressor surge, and that the boost may need knocking back in the area it's causing problems, How i really don't know?? can Boost be Limited in specific areas with the Autronics ECU?? anyone?

 

Almost sure it's compressor surge, and quite a common problem to get rid of so i'm told Turbo spooling to quickly in high gears i'm also informed, anyone else throw some light on this Bob "R" ??

 

sorry but there is no description of the problem? just a question on what the sensor is????

compressor surge can be a pain to resolve depending on setup etc..

Simon, Sorry for any confusion, I asked the original question on behalf of blueburle as its his car that has the problem of compressor surge, we noticed that the map sensor had an open ended pipe connected and wondered if it could be connected to the fault. Since my original post BB has spoken to various others and they have concluded that it must be compressor surge and i believe, will be in the hands of a highly reguarded autronics mapper shortly.

Once again thanks for your help and sorry for the confusion.
