There is a hard stop on the Eccentric cam, so at mac Ecc Cam- max valve life will be 9.7-9.8, N55 maybe 9.9mm. There is no getting more that the hard stop. If you program in 12mm, it will still only go to the max at the hard stop.

And it might not even go all the way to the hard stop. I think that the min and max hard stops are for the ECU to calibrate and check the range of the ECC Cam sensor.

Something like- Take a reading at close, zap the ECC Cam motor till it hits the max hard stop, take a reading and then back to the min hard start and then the engine starts. Now the ECU knows where the max hard stop is at.
