The only way people can understand it is a real function and exactly as the engineers defined it is show their content exactly as they wrote it.

Written any other way and people will just say it is just my view and ignore it.

Hence in research and review of flash files I find all major tuning products are ignoring this function and in fact if tire or wheel changes are made can induce engine drag on when it should not and the cause of crashes.

At this point I am looking at either a fix or a workaround.

In existing testing C6 Z06 owner simply went from a 325/30/19 tire to 345/30/19 which is a slight change ( changes made also in the PCM flash calibration) and it caused inducing engine drag to come on even at slow speeds with stock and modified tune.
