I've got a '12 Audi A4 with the 2.0t engine (EA888 gen 2, CAEB) and I'm trying to learn how to tune it. Just as a little background I'm pretty experienced with tuning, but on older systems that are not nearly as complex as this!
I started by making changes to driver-demand torque tables which seemed to have no effect. So I increased some other torque-related parameters, and now the engine is pulling timing like crazy! Even when not under much load... I could understand if it's knocking at high boost but it even happens at low throttle openings and manifold pressures.
Now here's the thing: I did NOT change any timing-related parameters! At least not intentionally.
"Before" and "after" tune files (the one with "2" in the name is the "before") and a short log attached. My laptop battery died so the log doesn't contain much, but it does show the problem.
Does anyone have any insight on this?
