What is the Start Stop system? Start Stop Disable

This is a promising and encouraging topic, as thousands of skilled engineers in large companies work daily to reduce the emissions of vehicle engines. This is something we all appreciate. However, the point is that these systems sometimes cause additional failures that lead to exorbitant and unnecessary costs, and that is something no one is happy or hopeful about!

One of these systems, which is as effective and deadly as a ninja's sword, is the start-stop system!

The start-stop system, like many recent technologies in the automotive industry, was created to reduce emissions.

You have probably thought about the long stops of cars on streets and roads and, as a passenger or driver, found yourself stuck in long traffic jams! This is exactly what the inventors of this system focused on and addressed. This is precisely where an idea can be developed to reduce wear and fuel consumption, but how?

How does the start stop system work?

The start-stop system is designed to give a command to stop the engine based on feedback from the driver. In most ECUs where the start stop feature is defined, this is done as follows: The feedback that the driver provides to the ECU comes through the pedals. In automatic or DCT vehicles, pressing the brake pedal after shifting to neutral sends the necessary feedback to activate the start stop system. In manual transmission vehicles, this feedback is sent by shifting to neutral and releasing the clutch. To put it more precisely, if we want to express this in ECU terms, the ECU responds to RPM, fuel, and torque data. In fact, to be even more precise, it is the data from sensors such as the wheel speed sensor and crankshaft sensor that informs the ECU about the vehicle's status. After all this, the ECU turns off the engine to reduce the combustion cycle and prevent emissions.

How do I turn off the start stop system? / Start stop button:

In some vehicles, there is a button for deactivating the start-stop system, which you can press to disable this option. Otherwise, if your vehicle does not have a start-stop deactivation button, the start-stop system will reactivate when you release the brake and press the accelerator pedal in vehicles equipped with automatic or DCT transmissions, or by pressing the clutch pedal in manual transmission vehicles.

This raises the question of how to deactivate this system if our vehicle is not equipped with a start stop deactivation button.

Or an even more important question exists: why should we deactivate the start stop system at all? What are the pros and cons of the start-stop system?

Pros and Cons of Start Stop Systems:

On the surface, it seems that start-stop systems reduce emissions, so what could be better than that? This is an important advantage, but it’s not the whole story.

If we pay a little attention, we realize that the repeated starts and stops of this engine are one of the reasons for higher wear and tear. This is because for the vehicle to endure multiple restart cycles, it requires stronger bearings, which will undoubtedly be more expensive. Besides this, any failure in these bearings can impose significant costs on the vehicle owner. Such wear and tear will also affect the starter and battery, necessitating more expensive models for them as well.

This wear can lead to impacts on the chassis and also cause vibrations and extra noise in the vehicle cabin. All of this worsens when there is no manual option to turn off this system!

Before we discuss how to disable this system from vehicles, we should mention that this system does not cause the engine to repeatedly cool down and heat up because the starts of this system are hot starts, and the engine temperature and parameters of the EGT table have not decreased. Additionally, this system does not affect other electrical components of the system, and in fact, other systems will continue to operate independently of the start stop system. In reality, the opposite process can occur in the vehicle; for example, if the vehicle's air conditioning system requires a restart for any reason, the engine will start again (which is also part of wear and tear!). Lastly, please note that the start stop system will not be active in sport and dynamic driving modes, and in fact, this system does not operate in these two driving modes.

How to disable the start stop system?

We are not concerned with those vehicles that have a start stop disable button, as the owners of these cars usually do not have issues with this system. However, for older vehicles that do not have this button, there is a need for a software removal of this system.

To remove this system software-wise, you should use the WinOLS software. In fact, WinOLS is the best option for manually removing this system through software. To do this in WinOLS, you need experience to understand the layout of this area in different ECUs. Sometimes, you may also need a Damos file because the method for implementing solutions varies among many vehicles.
