Bench Tuning
Tuning cannot be done directly through the OBD2 port, sometimes. This is when a bench tune is needed.
Bench tuning involves disconnecting the engine control unit (ECU) from the vehicle and connecting it to a specialized equipment on a workbench. The ECU will be then re-programmed with a custom software to optimize the engine’s performance. Bench tuning offers precise control over the tuning process and is ideal for advanced tuning, such as optimizing fuel and ignition maps. In order to bench tune, the ECU has to be removed completely from the vehicle, and specialized equipment is required. Therefore, cost will be different.
