How we prepare these files
Every Opel Astra-J order is checked against the uploaded file, not only against the model name. We verify whether the read looks original or already modified before preparing the file, and if something is unclear we contact you first.
Exact ECU match
The engineer checks ECU family, software version, read method, checksum requirements and previous tuning traces before preparing the modified file.
Service fit
Available options can differ between diesel, petrol, hybrid and gearbox files. Hardware-dependent services are confirmed from the file and vehicle details.
Clean order data
Year, engine, ECU, gearbox, tool and customer notes help us reduce back-and-forth and deliver the right file faster.
