Cobb 4.0 vs 4.1 stg1 st throttle - BMW 3-Series (E90 E92) Forum

gmazzu · 10-29-2012, 09:42 AM

Does anyone know the difference between the 4.0 an 4.1 code for stg1 stock throttle? I have been running the 4.1 code and recently flipped back to 4.0 and the 4.0 is simply smoother. The dip in on the throttle is just smoother, part throttle and initial acceleration. Anyone have any ideas?

Well the notes say very little, there is a dead spot in the pedal on initial tip in on the 4.01 where the on the 4.0 is just simply is smoother when applying the gas.

you could try to copy it over to the 401 and see if it changes anything.
