By choosing the appropriate gear, I only need to brush the brakes a few times on the steepest sections.
But with the fully computerized B-motor in the 230i, I can't find a combination of settings to achieve anything similar. I can downshift, and engine speed increases, but the drag does not (I suspect the valves are being held open specifically to decrease pumping losses). And after a couple of minutes, the computer upshifts again, anyway. I've tried different combinations of sport/comfort/eco and gear-lever/paddle shifting, and am unable to hit on a suitable combination.

At what RPM do you find you have no engine braking? You have ~7000 to play with, with a wide variety of response.
