Talking more videos...

Hi again

Below are new videos I made tonight. I also analyzed the performances based on the videos and the results are:

factory | 50-150kmh (7.5s)
ess stg2 | 50-150kmh (7.0s)
ess stg2 | 100-200kmh (12.5s)
ess stg2 | 20-100kmh (~4.5s) with wheelspin and DTC on...

The most notable difference was that in S1 there was wheelspin on all runs with stg2, and none with factory ECU on this road!

All videos were made without passager this time, and password is "BMW". Let me know what you think.

ESS Stage 2 From 20kmh (with wheelspin) :

high speed run

From 20kmh with open window

From 20kmh (no wheelspin)

high speed run
Little known facts about BMW: 1) The N54 is still in production and used in the current Z4 35i and 35is. 2) In a Z4 you can get sport+ steering combined with normal suspension etc by selecting DSC=off. (Update: DSC=off also offers sports steering in the M135i) 3) All Z4s with 19" wheels are still only offered with the worst performing OEM tires ever sold with a DCT equipped BMW (Potenza RE 050 RFT).
