SIMOS boost patch tool

This tool allows you to patch the boost pre-control maps (ip_fac_bpa) in SIMOS 18 to have RPM and Boost setpoint on the axis instead of intake and exhaust factors, making tuning much simpler, especially when the turbocharger has been upgraded.
You will receive a patched file and a CSV so that you can import the new maps into WinOLS. Just change the axis values on the maps to reasonable values. The maps will be in the "VehiCAL Boost Patch" folder.
The cost is 15 credits. You can re-use the patched file across different ECU's.

  1. Unlock the ECU for OBD writing with tool of your choice (flash any modification to calibration area via OBD protocol).
  2. Read the ECU in boot mode (or virtual OBD read on tools that allow full write).
  3. Upload the file here.
  4. Checksum and write file to ECU in boot mode.
