Transmission/TCU Alpina Reflash Thread, Flash Options, DIY Instructions, etc.

Instead of burying this info in one of the other threads, I decided to make a new one with some additional options for transmission flashing.

Anyone with a cable and BMW standard tools/WinKFP up and running can do this. I followed these instructions when flashing mine:

It's very doable. I had just figured out how to code (thanks improvius)...so I was intimidated by the whole process, but it went pretty smoothly.

Here are some of the maps available for flashing to your 6 speed autos...

Quote:
7601492 (stock flash)

7603527 (BMW 2011 Trans Flash)
-No gear indicator (D1, S1)
-D shift rpm raised slightly (1800-2000) compared to Alpina B3
-Downshift rev match not like Alpina but better then others
-6800rpm shift

7615835 (Alpina B3 trans flash)
-Gear indicator (D1, S1)
-D shift rpm relatively low
-S mode shift rpm 2800-3000
-Great rev match downshifting
-7000rpm shift

7603537 ("Old / Alternate" Alpina B3 trans flash)
-same as 7615835 except:
-smoother
-slightly higher RPM D mode upshifts

7603541 (Euro Sport Flash)
-no gear indicator in Drive but you get the S1, S2 in S mode / M1, M2 in M Mode
-S mode bit more aggressive than stock
-D drives just like the stock

7601494 (US Sport Flash)
-D mode feels stock
-S mode stays in gear longer than the B3, Shifts at about 3300 - 3500
-M mode is more impressive than the B3 at shifts
I used the '537 and I really, really love it.

The car drives SO much better, in any mode. Really, really impressed with it.

If you're thinking about it, don't hesitate. If you're local to Philly, I can do it for you too.

It's factory BMW software no warranty concerns at all.
