Which ECUs do you support?

Bosch EDC15/17 (incl. EDC17C46/C50/C54/C64/C74), MED17, Siemens SIMOS, Continental SID, Delphi DCM6.2/DCM3.x, Magneti Marelli, Temic for TCU. Database is constantly expanding — if your ECU is missing, the engineer disassembles the original via Ghidra and adds it.

What format do you accept for the original ECU?

We accept .bin, .hex, .ori — standard dump from any programmer: KESS3, Autotuner, MPPS, Trasdata, PCMflash, CMD Flash, KTAG. OBD or Bench read — makes no difference.

Who recalculates the file checksums?

Checksums are recalculated automatically in WinOLS5 — all major algorithms supported (Bosch CRC32, Siemens, Delphi, Magneti Marelli). The output is a flash-ready file, no need to run it through a separate checksum solver.

How long does it take to return the Stage file?

30-60 minutes during business hours. The order is created in the portal, the engineer sees it immediately, status updates in real time. Urgent cases can be flagged — we take them first.

Do you do free revisions if the file did not work?

Yes, we redo it at no extra charge. Send the OBD log after flashing — the engineer checks the actual parameters and corrects the calibration. Communication directly via Telegram, no ticketing systems.

What is the payment model — subscription or credits?

Payment in euros, one-time per order, no subscriptions (1 € = 1 portal credit). No monthly fees like ATF, Magicmotorsport and other services.
