How it works

Read the ECU with any tool (KESS, KTAG, Autotuner, MPPS, bench or OBD), open the .bin in Softechpro, select the services above, and the software applies the changes and recalculates the checksum automatically — ready to flash back. Coverage is strongest on VAG, BMW and Mercedes (Bosch EDC15/16/17, MD1, MG1, MED17, Siemens, Delphi). New accounts get 5 free files to test compatibility before buying. We do not offer manual or custom tuning — services are automatic where the ECU is supported.
