Alpina B3 Transmission Flash

Available for: E9x 335i models (N54 or N55)
Build Dates: 3/2007 or newer
Requirements: Automatic transmission

Benefits of the flash:
  • Faster and more responsive shifts
  • Faster paddle response
  • Faster launches
  • Improved rev-matching on downshifts
  • An overall improvement in every day driveability
  • Gauge cluster will show the gear (D1, D2, etc.) rather than just “D”
  • The B3 is the Alpina version of the E9x 335i and is available in Europe. The car has the same transmission as the 335i but uses a different software version with different settings. Because the transmission is the same and the software is OEM, it can be safely flashed to US cars to allow 335i owners to take advantage of the improved performance.
  • E9x M3 DME 240E Flash
  • Available for: E9x M3 models
  • Build Dates: All
  • Requirements: None

Note: Update your DME to the latest available version from BMW. This is not a tune but if your M3 is running older software, this is a must-do upgrade. The latest software is an improvement in drivability over the older versions in terms of smoothness and responsiveness.

  • E9x M3 Euro DCT Flash
  • Available for: E9x M3 models
  • Build Dates: All
  • Requirements: DCT
Benefits of the Euro flash:
  • DCT defaults to D2 and it remembers S mode (as opposed to defaulting in S3 and remembering D mode
  • Cold starts are improved and smoother
  • Cold up and down shifts are improved and smoother
  • The European M3 has the same DCT as the US M3, they just run different software versions. For many, having the DCT start in D2 is prefered over S3, since the car is cold and will be driven gently anyway. In addition, your preferred S setting will be remembered for when you’re ready to switch to manual mode.
  • Note: Standard US software updates are also available.
  • E6x M5/M6 Euro SMG Flash
  • Available for: E6x M5/M6 models

  • The European M5/M6 has the same SMG but runs a different software version than the US models. The Euro software can be flashed directly to the cars without modification, and US owners can take advantage of the improved performance.

Benefits of the M3 CSL flash:
  • 4,500 rpm launch control
  • Smoother, faster launches
