Anyone have any real dyno data? Not just graphs, but some real numbers recorded at regular intervals?
180TT FWD would be ok
180TTQ data would be even better
180TT w/Garrett chip would be awesome!

And of course, all of the above would be best.

I know its been done already but I want the data so I can calculate shift points for the TT.<p>Aviator Grey 2000 180TTQC

For "step" data, about your only choice is Superflow's AutoDyn chassis dyno. Most chassis dynos (Dynojet, etc) are just calibrated inertial wheels which the car accelerates. No easy (read cheap) way to get steady-state numbers. AutoDyn is inertia plus eddy current absorbers so you can get data at finite rpm steps, or at programmable acceleration rate.

Last I checked, quattro models were not available.

I'd suggest that empirical testing of shiftpoints might be easier. Do one gear change at a time. The procedure isn't complicated but explanation kinda lengthy for here. It's not hard on driveline either.
