Checksum Correction Frequently Asked Questions
- What is checksum correction?
- It corrects supported file-integrity areas after a file has been modified, so the ECU can validate the file correctly during writing or operation.
- Is checksum correction tuning?
- No. It does not change performance or diagnostics by itself. It is a technical file validation step.
- Can every checksum be corrected?
- No. Support depends on ECU family, file format and read method. We confirm from the uploaded file.
