I have tested both 6AT and 7DKG (my car) 335i, the issues as below: -

1. 6AT running 1,900 rpm can reach 100km/hr at 6th gear;
2. 7DKG running 2,100 rpm to reach 100km/hr at 7th gear; before upgrading the firmware of ECU, running 2,000 rpm to reach 100km/hr at 7th gear.

Can anyone pls explain why were the above happened? Does this mean 7DKG will consume a little bit more gas than 6AT?

p.s. hope there is 7DKG owner can explain whether his car is same as mine which running 2,100 rpm to reach 100km/hr in order to make sure my gearbox is in fine condition

Thanks in advance : )
