ECU tuning files
& remapping files
for workshops

Tell us which Autotuner protocol and read method produced the original file. OBD, bench and boot access depend on controller support and can expose different data. State whether your tool is Master or Slave before opening the first order; the file path and any Master relationship need to match the service handling the job.

A KESS3 order should identify the ECU or TCU actually read, the selected protocol and the access mode available under your activation. Send the original tool export without changing its structure. An engine read and a transmission read are separate datasets. Where a Slave configuration is involved, confirm the Master arrangement before purchasing the calibration work.

For Magic Motorsport Flex, include the controller identification and the OBD, bench or boot method used where supported. Explain whether the export contains the calibration area or a broader backup. Keep any tool-specific container intact. Knowing how the data was obtained helps us agree which file is to be edited and which output your writing workflow requires.

K-TAG jobs use the bench or boot procedure supported for the specific controller. Retain the original memory exports and identify the protocol that created them. The file intended for editing is not automatically interchangeable with every item in a full backup. A Master/Slave relationship, if present, is checked before the order moves into development.

Create the file order in the portal and attach the unmodified source data. Include the flash tool, controller identification, read method, hardware configuration and the requested change. Label a virtual read clearly, and tell us if the starting software has already been modified. Maintain a separate original backup rather than using an edited delivery as your only reference.

After delivery, check that the file belongs to the correct order and follow the tool instructions for writing. If a revision is required, keep the delivered version and relevant logs with that order. Describe the operating condition and observed behaviour. A log captured under known conditions provides a better basis for an engineering discussion than an isolated screenshot with no indication of the file or vehicle setup.

Use the price list to review base services, credit packages and additional options. Confirm what is included before combining selections. The relevant price is the scope agreed for your job; a database entry or an ECU family name does not confirm that every optional function is available. Mapswitch and definition enquiries are scoped separately rather than assigned an invented public credit figure.

Order files and manage credit in the customer portal. Before your first purchase, confirm the tool configuration and export format with the service, especially for an encrypted Slave file.

ECU-Tuningfiles and SL Performance develop the offered files in-house in Bochum, Germany. Contact the technical service through WhatsApp, the contact page or your portal order. Include the software identification and the work you need.

For DAMOS, A2L, WinOLS MapPacks or CSV and JSON definitions, attach the original BIN/ORI file. A controller name is useful for searching the catalogue, but the binary layout and software version determine whether a definition fits. If your model or software reference is not listed, send the original data for review rather than choosing a similar-looking entry as a substitute.
