About this calibration file
The Stage 1 calibration for the Opel Vectra 1.8L Petrol is a drop-in remap that works on completely stock hardware — no turbo, injector, intercooler or fuel-system upgrades required. Injection timing, boost targets, rail-pressure limits and torque maps are rebalanced to extract the safe headroom the OEM leaves untouched for fleet-fuel tolerance, altitude margin and warranty buffer.
This file matches a Siemens ECU with hardware number 5WK90730. 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.
