seems to be different issues between the M35i and the rest-of-the-world version of the FWD S2.0i.

At least on my FWD (7 speed dct), the stopping is smooth...no tranmission grabbing. Even in crawling traffic it's pretty good.

My main issue is the strong hesitation/lag when I try to accelerate fast from standstill, or when I need to quickly accelerate when already cruising say at 100kmh.

The BMS pedal tuner helps a little, but doesn't eliminate what is either transmission lag, or turbo lag. Though I can't see how turbo lag could be that bad in a modern small-turbo, relatively low power engine. (remembering the non US 2.0i has only 141kW). Which is less than my 1994 Nissan 200SX 2 litre turbo, which had no noticeable turbo lag
