About this calibration file
The Stage 4 calibration for the 2004 Opel Kadett 2 0l Petrol is a built-engine tune. It assumes forged internals, large-frame turbo, upgraded transmission or clutch, and a standalone pre-tune dyno pass. The file is meant as a safe starting map for a professional tuner's in-car refinement.
This file matches a Bosch ECU with hardware number 0261203372 and software version 90351646. 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.
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.
