It allows you to access and modify various control units in your car, including the one responsible for the Start-Stop system.

Why Disable Auto Start Stop?
While the intended goal of Auto Start-Stop is noble, many drivers find it intrusive or disruptive. Some common reasons for disabling it include:
- Reduced Starter Lifespan: Frequent starts and stops can put extra strain on your car’s starter motor.
- Lag in Takeoff: Some drivers experience a delay when pulling away from a stop as the engine restarts.
- Comfort and Personal Preference: The constant engine cycling can be annoying for some drivers, especially in stop-and-go traffic.
