@skysurfer and I flashed his 535i which is SAT shifter retrofitted to the Sport Automatic Transmission flash using Assembly Number 7601458.
At first I thought maybe we could try the Alpina flash, but after checking out his UIF information and looking at his current assembly number, I decided not to because his ECU type is GKE215. So the only options were standard transmission or sport automatic transmission. So we rolled the dice and flashed it to the Sport A/T because he was alreayd on the lastest standard transmissions flash and sure enough it works and works very well. D is still just D, but SD is now S1-6. According to Skysurfer, shifts are much smoother in D, and quicker in Sport or Manual. Rev matching is also better.
So Ill leave it at that and Ill let Skysurfer chime in and give you the 411 because he knows his car and he can tell you first hand the flash made.
If anyone needs any assistance with setting this up, please let me know.
