Grand Prix ChiptuningCHECKSUM SERVICE
WINOLS · ECU CHECKSUM

Checksum correction
Bosch MDG1

Online checksum verification for Bosch MDG1 and supported MDG1 EEPROM files.

Check your file ↗

Bosch MDG1 files differ in memory regions and readout methods. Processing requires a raw binary file; the ECU name or file extension does not establish compatibility.

Preparing your file

Prepare a matching original for MDG1 EEPROM. Modified-only mode is available when the module supports processing your file without an original.

Formats: .bin, .mpc, .mod or no extension. Maximum 19 MiB. The service verifies checksums, not calibration quality.

Processing details

After processing, the service checks the WinOLS report and compares the result with your upload. Payment appears only after a confirmed correction; an unverified result is not presented as a success.
