Launch control is a software function that holds engine speed and torque delivery at a predefined value so the vehicle can start from standstill as fast and as controlled as possible.
What is launch control?
Launch control is an engine management function developed so a vehicle can start in racing launches without wheelspin and within the engine's most efficient rev range. While the driver keeps the throttle fully pressed, the ECU holds the engine speed at a predefined level; at launch, torque is delivered in a controlled way without driver intervention.
How does it work?
When the function is activated, the ECU applies the defined rev limit (launch RPM) and may use strategies to keep boost pressure high at this limit. When the brake pedal is released, the vehicle launches with the torque that is ready. Parameters such as launch revs, torque reduction and traction control can be adjusted in the ECU software.
How the function works varies with the gearbox type (manual, DSG/dual-clutch, automatic).
Which vehicles can it be applied to?
Suitability depends on the ECU model, gearbox type and the vehicle's hardware. Not every ECU supports this function in software. When you select your vehicle in the panel you can see whether the option is offered for it.
Things to note
- Launch control puts high load on the gearbox and drivetrain; these parts need to be healthy
- The function is only suitable for track, drag or closed-area use
- It must not be used on a cold engine or a gearbox that has not warmed up
- Repeated launches can shorten the life of components
When creating a request
Launch control can be requested as an option together with a main software level such as Stage 1/2/3. Stating the gearbox type and your target launch revs in the request note speeds up the job.
Frequently asked questions
No. Suitability varies with the ECU and gearbox design.
Because it puts high load on the drivetrain, there is a risk of damage on poorly maintained or weak components. Regular and conscious use is important.
The function is designed for racing and closed-area use; using it in traffic is not recommended.
