What is Launch Control and what does it offer?
The Launch Control It's an ECU function that allows for accelerated starts from a standstill with maximum traction control. When activated, the engine maintains a target RPM with the turbo already pre-charged, so that when you release the clutch (or the brake in automatic transmissions), the maximum available power is delivered instantaneously, minimizing wheel spin and optimizing 0-100 km/h acceleration.
Many sports cars include factory-installed launch control, but it's calibrated very conservatively for reasons of overall reliability and legal protection for the manufacturer. Our service Calibrate the Launch Control to your liking depending on the hardware, the type of surface where it will be used, and the client's objective.
What do we specifically calibrate?
- Target RPM: the engine speed at which the engine stabilizes when LC is activated (typically between 3,500 and 5,500 RPM depending on the engine).
- Precharged turbo pressure: how much boost the turbo maintains while the vehicle is stationary with LC active.
- Injection during the waiting phase: balanced to avoid excessively stressing spark plugs or raising exhaust temperature.
- Clutch transition: In DSG transmissions, engagement time and optimal pressure. In manual transmissions, smoothness of initial gear changes.
- Traction control: synchronization with ESP/ASR when applicable.
- Maximum activation time: protection to avoid leaving LC indefinitely due to driver forgetfulness.
- Recalculation of the checksum.
Types of Launch Control
- LC streetConservative, 3,500-4,000 RPM, active thermal protection, intended for occasional use.
- LC sporty: more aggressive, 4,500-5,500 RPM, designed for asphalt with good grip.
- LC competition: configured according to category regulations (rally, drag, circuit).
- Multistage LC: configurable by the driver using the pedal or buttons.
Minimum recommended hardware
An aggressive Launch Control puts demands on the hardware. We recommend considering:
- Clutch in good conditionLC wears out clutches. A 50% clutch with a lifespan will not withstand more than 10-20 aggressive activations.
- Proper refrigeration: In diesel and TSI preparations, aggressive LC greatly increases the EGT.
- Consistent tiresWith commercial tires there is no traction to take advantage of aggressive LC; with semi-slicks there is.
- Robust boxDSG requires prior tuning; manuals with stock clutch can handle up to certain torque levels.
ECU compatibility
| Manufacturer | Supported ECU families |
|---|---|
| Bosch | MED17 (full range), MG1CS, EDC17 in sporty diesels |
| Continental | Simos 10/12/18 |
| Delphi | MT86, DCM6.2V |
Launch control is most effective in turbocharged petrol engines with quick response. It also works in modern diesel engines, although with less dramatic effect due to the different torque delivery.
Common combinations
Launch Control is a standard part of the sports preparation package:
- With Stage 2: essential to take advantage of the new power outputs.
- With Stage 3: part of the complete competition project.
- With DSG TuningThe box needs specific calibration to withstand repeated LC.
- With Vmax and HardCut: complete competition pack.
Usage considerations
Launch Control is a tool, not a toy. We recommend:
- Use it in controlled environments (circuit, airfield, track day).
- Don't overdo it: 2-3 outings per session is enough to enjoy without getting worn out.
- Allow the engine to cool between activations.
- Check the clutch periodically if it is used intensively.
Professional notice: This service is aimed at workshops and professionals in the automotive sector. It is suitable for off-road applications, agricultural and industrial machinery, racing vehicles, repair of cloned or replaced ECUs, and cases of failure where the original hardware is no longer viable. The final application to the vehicle and its subsequent use are the sole responsibility of the professional installer and the end user, in accordance with the applicable legislation in each country.
