Agreed, the purpose of the three modes (eco comfort sport) is to allow task-specific tuning, and one would think that sport mode, particularly using launch, would optimize acceleration, and a sub 4 sec 0-100kmph time is a marketing rubicon that would help silence the 'not a real performance car' critics.

Perhaps the conservative reliability designers won out...

It would be nice to hear from the experienced 1/4 mile folks to see what results tunes are providing.

How does it work? Does the stock car have 3 sets of engine mapping for the 3 modes eco/comfort/sport?
Is Alex’s tune only for sport or does it not work like that?
