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 0261206122 and software 350079.
-
Pay and download
Card, Apple Pay or Google Pay. The file is in your account straight away.
-
Write it and drive

What the car needs
Required modifications: Stage 3, Petrol.
Hardware
- Hybrid or larger turbocharger
- Upgraded high-pressure fuel pump and / or injectors
- Front-mount intercooler upgrade
- Sport / decat downpipe + free-flow exhaust
- High-flow air intake
- Uprated clutch (manual gearbox)
Software / calibration
- Custom map dialled to the installed turbo, injector and intercooler spec
- Boost, fuelling, ignition / injection timing rebuilt around the new hardware
- All safety limits (knock, EGT, lambda, rail) re-tuned to match
- Drivability and torque-by-gear shaped to match the hardware
Stage 3 is hardware-matched. Send your turbo / injector / intercooler / clutch spec at checkout so the file is calibrated to YOUR build: typical projection above is a guide, final dyno depends on installed hardware.

About this calibration file
The Stage 3 calibration for the Audi A4 2 4l Petrol targets a hardware-upgraded setup — hybrid or larger turbocharger, upgraded injectors, high-flow fuelling and in most cases a full exhaust. Maps are redrawn for the new airflow envelope with re-scaled MAF/MAP, torque limiters, smoke limiters and boost PID re-tuned.
This file matches a Bosch ECU with hardware number 0261206122 and software version 350079. 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: 281 HP and 419 Nm at the crank — a gain of +111 HP (65%) and +149 Nm over the factory 170 HP / 270 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.
