Yes, 7615835 is the latest (2/23/2010.) Some folks prefer 7603537 (4/23/2009.)

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

My personal experience, but, I've only had the car for 6 or 7 weeks now:

7615835 - shift points in D are way too low. 6th gear going 40mph is a PITA and it just makes the car feel meeeeh unless you pound the gas in D. S mode is nice and I almost never use M but the shifts were pretty smooth

7601494 - shift points are higher and much less annoying. You miss out on the D1...6 but I wasnt a fan of that to begin with nor did I find it necessary. S mode is much more responsive, higher shift points and IMO smoother shifts than 7615835. D does have some 'nuances' I'm trying to get used to and its definitely not stock. I havent even bothered to 'fix' my paddles since I never use them and the gear selector still allows me to manually shift but maybe I'll do it tonight.

Anywho, enough about me. I found this on another thread once I realized 7615835 was annoying me and I was actually trying to find a way to go back to stock:



Hope that helps someone

Banana,

Do you know what models/years/production dates these are good for?

I have heard the Alpina B3 flashes are only good for 3/07 and newer production dates (I'd love to know what the change was to hardware/modules/software that made this work as of 3/07).

Thanks!

The interface and ECU of the car changed, so only after 03/2007 has the updated parts for it to actually work.
