Start & Stop Removal — Automatic Engine Stop Deactivation

Start stop removal is a professional ECU software modification that permanently disables the automatic engine start/stop function present in most modern vehicles.
While the feature is designed to reduce fuel consumption and emissions by shutting the engine off when the car is stationary, many drivers find it intrusive and inconvenient in daily use.
With this calibration, the start/stop system remains deactivated by default every time the engine is started, so the car behaves like a conventional vehicle without requiring manual deactivation after each ignition cycle.

How the start stop system works

The automatic start/stop function uses information from several sensors (battery charge, brake pedal, clutch position, engine temperature, and A/C load) to determine when to switch the engine off during idling.
When conditions are met, the ECU shuts down the engine to save fuel and restarts it as soon as the driver presses the clutch or releases the brake.
Although efficient in theory, this repeated stop/start cycle can cause additional wear on components such as the starter motor, flywheel, or battery, and may interrupt comfort systems like air conditioning or cabin heating.

What start stop removal does

Our start stop removal service modifies the ECU calibration so that the system remains inactive by default.
The start/stop button and control logic remain intact, meaning the system can still be re-enabled manually if desired.
This solution does not exclude or remove the module physically — it simply prevents the ECU from activating the stop/start cycle automatically.
It is a software-based deactivation that keeps all diagnostic and safety functions operational.

When start stop removal is recommended

• When the start/stop feature causes discomfort or delay in daily driving (urban traffic, short trips, frequent stops).
• When retrofitting heavy-duty batteries, upgraded starters, or tuning applications where frequent engine restarts are undesirable.
• For motorsport or off-road vehicles requiring consistent engine operation without idle shutdowns.
• When the system cannot be permanently disabled through OEM menu settings.

Benefits and technical notes

– The engine stays on continuously, ensuring smooth operation and consistent throttle response.
– Reduces wear on the starter motor, flywheel, and battery system.
– Keeps all ECU diagnostics and protections active (no DTCs or error messages).
– The start/stop button can still be used manually if the driver wishes to reactivate the system.
– Tested on bench and dyno for stable behavior and safe integration.

Note: The start/stop module must be fully operational before performing this calibration.
This service does not repair defective hardware — it simply keeps the start/stop function deactivated by default.

Additional details

The start stop removal modification is performed directly within the ECU file using official reading/writing tools.
No physical wiring or emulators are required.
It is fully reversible — the stock file can be restored at any time if you wish to re-enable automatic start/stop.
All solutions are bench-validated and dyno-tested to maintain OEM-level reliability and comfort.
