Don't do it, one of the reasons we don't see a lot more carnages in this transmissions due to improper tuning techniques, is the fact that the trans can adapt to a bunch of variables, being able to learn shift pressure and speed to attain certain shift feeling or target shift setup. if you dumb it down disabling the learning, your trans won't last very long. The learning is a needed help/evil depending how you're shift pressure/speed is setup

, for instance, and unrealistic shift speed would make the trans shift erratically among other settings that come with unrealistic lower shift speed.
