How it works
-
Read your ECU
With KESS, KTAG, AutoTuner or Flex. Keep the read: it is your way back.
-
Match the numbers
Your read must show hardware 5WK93608 and software 777227.
-
Pay and download
Card, Apple Pay or Google Pay. The file is in your account straight away.
-
Write it and drive
Write it back the way you read it. Not right for your car? We correct it free.
What the car needs
Required modifications: Stage 2, Petrol.
Hardware
- Sport / decat downpipe (or sports-cat)
- High-flow air intake
- Optional: front-mount intercooler upgrade for sustained boost
Software / calibration
- Cat-warm-up & secondary lambda re-mapped for decat hardware
- Boost target raised in line with cooling capacity
- Knock / ignition advance re-trimmed
- Idle and load-transition tables refined
Stage 2 keeps the factory turbo and internals. Final figures vary slightly with the exact hardware fitted.

About this calibration file
The Stage 2 calibration for the 2006 BMW E90 E91 Petrol is written for vehicles with supporting bolt-ons: a higher-flow downpipe or sports catalyst, upgraded intercooler and upgraded intake are recommended. Boost targets, fuel-rail pressure, injector duration and VGT positioning are pushed further than a Stage 1 map while keeping exhaust-gas temperatures inside safe bands.
This file matches a Siemens ECU with hardware number 5WK93608 and software version 777227. Verify both identifiers in your flashing tool before writing — an ID mismatch is the most common cause of a bricked ECU. If you are unsure, upload a read of your original file via the file-request wizard and our engineers will confirm compatibility before you flash.
Projected output on a healthy, stock-hardware example of this engine: 386 HP and 540 Nm at the crank — a gain of +80 HP (26%) and +140 Nm over the factory 306 HP / 400 Nm baseline. These numbers are sourced from our Vehicle Performance Database, which aggregates dyno results across this engine family. Real-world gains depend on fuel grade, ambient temperature, mechanical condition and intake/exhaust state.
The file is delivered as a ready-to-flash BIN (and ORI backup where applicable) compatible with all major tools — KESS V2/V3, KTAG, AutoTuner, CMDFlash, Dimsport New Genius, MPPS, Flex, BFlash, PCMFlash, MMFlash — via OBD, bench or boot-mode as supported by your ECU family. Checksums are pre-computed and verified; no additional checksum tool is required. All files include a free revision if post-flash logs reveal a fuelling, boost or EGT issue.
