Mark, you said the new mapping for the 540's will be 91 octane; here is a current thread from bimmerforums about a new 93 octane m60 EAT chip. Is this chip different/more powerful than the new chip for non-ews 540's or is it the same?
Well I finally received the file to burn the 93 octane chip from Mark D. I have to say that there is a rather noticeable difference between the 91 octane chip that I had before and this one. This guy knows his stuff. I requested an increase in low to mid throttle acceleration and got more than what I expected. In a nutshell the car is fast. Around town the car picks up speed quickly and there is a stronger pull at 3500 rpm than before. Highway speeds climb quicker than before and triple digit speeds are attained much easier. The car feels like the pedal is much lighter and takes little effort to move. Highly recommended for those wanting a bump in performance from there original EAT chip or those contemplating purchasing for the first time.
I hope to have a dyno chart soon.
