End‑to‑End Tuning Workflow

You’ve learned the theory and practised individual skills; now it’s time to put everything together. This module walks you through a complete tuning session using the tools on this site—from opening a raw file to producing a validated, ready‑to‑flash tune.

🔁 Full Workflow Overview

1. 1 Inspect the binary
   Open your stock `.bin` file in the Binary Editor. Check the file size, structure and look for any obvious anomalies.
2. 2 Visualise a map
   Use Map Viewer to paste in a section of the binary or import a predefined map profile. Identify key maps like torque limiters or fuel maps.
3. 3 Adjust values
   Copy the map values into the Map Scale Adjuster and apply a modest change (e.g., +10 % torque). Paste the adjusted values back into the ECU Map Editor and smooth any spikes.
4. 4 Simulate results
   Run your modified map through the ECU Remap Simulator. Check torque, AFR, boost and temperature graphs. Adjust your scaling if simulations show unsafe conditions.
5. 5 Fix checksums
   Load the modified binary into the Checksum Calculator. Auto‑detect the checksum regions, fix them and export the corrected file.
6. 6 Save & document
   Save the validated file with a clear name (vehicle, date, version) and record your changes in a tuning log.

🧠 Tips for Success

• Work incrementally: After each adjustment, simulate and review data instead of making multiple changes at once.
• Keep backups & notes: Save each version of your file and document what you changed. This makes it easier to revert or understand results.
• Test safely: Before flashing a real ECU, test your tune on a spare ECU or simulator. Monitor for knock, temperature rise and unusual behaviour.
• Learn from data: Use logs and feedback from the simulator to refine your maps. Tuning is an iterative process.

✅ Key Takeaways

• Combining your knowledge of binary structure, map scaling, smoothing and checksum correction allows you to produce a complete tune.
• The recommended workflow is: inspect → visualise → adjust → simulate → fix checksums → save.
• Practise the workflow on sample files before attempting to tune a real vehicle.
