These baseline maps provide a starting point for tuning and are designed for specific engines. They are not guaranteed to work correctly out of the box and may require adjustments to fit your particular setup. Always treat these maps as a foundation to build upon and make further refinements as needed.
It is critical to verify all assigned outputs and ensure they match your wiring. In the software, go to “Tools / Assigned outputs” and “Tools / Assigned inputs”. If the assignments do not match, do not load the map to your ECU. Adjust the outputs as necessary before proceeding.
This base map was created using EMU PRO version 225.x.
