    As I am reading the service manual, is says that cars with out cats have a CO adjuster on the Mass air flow sensor.

    In the US version (or other cars with CATS) the ECU completely ignores this signal.

    Anyone have a car without cats?

    Exactly....my us version can not be adjusted.

    I'm curious if I can copy the EPROM from a no cat car and put them in mine.

    I have no cats or precats so why not.

    I thought every 512 TR came with cats!

    Only some came without pre cats but still with the main cats.

    But complete without cats?

    Christian, do you know if they can tune your car's CO level using the mass air flow sensor? Maybe your engine tech can tell you.

    My statement earlier comes from something I read in the English translation of the factory workshop manual (WSM). It is possible that they meant to say "precat." That would make sense since the Motronic would need an O2 signal usually mounted in the cats.

    Newman or Rifledriver, do you know?

    AFAIK all airflowsensors ( may be wrong word?? ) at a K-jetronic or KE-jetronic can be adjusted with a 3 mm allen key. you only have to remove the cover srew first

    True...but read what I have posted....the ECU will ignore the adjustment if the "car has cats"

    Do you still have a 512tr Ecu? Can you copy the eprom?

    If you bought a car that had cats I would take that up with the PO.... though you'd think you'd notice them at the PPI

    I dunno what all this talk of cats is.... my car clearly has raccoons.
