36psi boost on stock equipment

[MrFwibble]

Well, now that I've got your attention with that outrageous subject I have a wee issue.

Column U shows its stuck reading maximum boost value.

I have replaced the MAP sensor (G31) twice now, no difference. The error code comes back instantly without even starting the engine.

Has anyone seen this before? I suspect faulty wiring, but open to suggestions. DV was replaced as matter of course just in case. Old one was fine.

Oh, and does anyone know where I can find a pin diagram to see where the wiring goes to on the ECU? Might try running a new cable.

Been searching for a pin diagram but getting nowhere.

Would anyone have a picture of their connector on top of the map sensor with the colour/order of the cables? Forgot to take a note before taking it apart, oops.
