Did you remove the radar? If you didn't remove anything, it will calibrate itself within a 1,000 miles regardless.
I replaced a radar on an AP 2.0 car and it some how programmed itself and calibrated and autopilot works now. Just have to drive for a good bit.
Oh one question. On the cluster/speedometer, does your car detect lanes?
Only once I start the car(if the car has been off for a while) and it detects the lanes(or at least it tries to) for only a few seconds... then it completely disappears from the speedometer.
