Stabilise GT3 G2 akin to ACC?

I mean, unfortunately these things are not democratic or operate by majority. With reference at least to the throttle model, it appears that yes, basically only in AMS1 and 2 is the throttle model correct, as explained by the person I mentioned in the post. Admittedly this is not enough to yield the entire "solution" and you may be right about the TCCUT levels not being set to levels lower than in other sims. But then surely this is not unrealistic per se, but a specific choice of TCCUT? This is similar to the lack of flexibility of differential setup in ACC that you don't get in AMS2 - the number of clutches and preload in ACC are not as variable as they are in AMS2 - they had to make implicitly some choice for these parameters in ACC, and may or may not have picked good ones. Something similar has happened here in AMS2.

You may stlll be correct, but the argument that the majority of sims doing something means it is correct is not valid.
