    Well the support people got back to me and they can't find anything wrong! I guess I'm probably remembering wrong and those were the shift points all along. They're weird, but if the RPM was higher...

    Steven,

    Thanks for letting us know about this!

    How can I tell if I'm affected by the issue? I do have one of the cars in question ('12 A4 2.0t).

    It is, but on this transmission 6th gear is 1:1 ratio so output shaft speed = input shaft speed. And input shaft speed = engine RPM minus a little for torque converter slip.

    For comparison, here...

    Editor showing wrong shift points for ZF8?

    Okay this is a weird one, wondering if anyone has any thoughts? I'm fooling around with tuning my '12 A4 with 2.0t engine and ZF8 transmission.

    Technically that's not a "MAP" sensor, it's turbocharger outlet pressure. Under boost it'll give a value equal to manifold pressure plus drop across the throttle, but it won't show vacuum because...

    Ah okay I had you confused with someone else. I'm 99% sure that engine doesn't have a MAP sensor. But it's similar enough to my B8 that I'd think the ECU would calculate and output that parameter.
