    Change values on Boost reading

    Is it possible to change the millibar to psi or bar reading in ECU boost section?
    Trying to see if my turbo is holding boost and the correct amount.
    I have a 08 passat 2.0T 6 speed manual car.
    Does anyone know what stock boost levels are on the k04 and what RPM it will start building boost?
    Is there way to log a graph or do a test pull see how it is running?
    Thank you in advance

    VCDS will only display what the module sends it. However, millibar to bar is an easy one - just divide by 1,000!

    Also, hit the [Log] button, to, erm, log the MVB you have displayed...

    Somehow, I don't think that VW/Audi would provide a spec for the "correct amount" in PSI.

    The engineering problems are likely insurmountable. It would be like proposing to land a rocket booster section on a barge floating in the middle of the ocean.

    The question is not whether VCDS offers such tests, but whether the ECU offers such tests that VCDS can initiate.
