Preset Ultimate Control

Sprint Booster comes with 3 Acceleration modes/ presets ( OFF / SPORT / RACE ):

OFF mode – Sprint Booster is deactivated. The response of the car has the factory settings.The LED of the Selector switch is OFF.

SPORT mode- Sprint Booster provides improved response  up to 30%. The LED of the selector switch in Sport mode is Green.

RACE mode – Sprint Booster provides improved response  up to 60%. The LED of the selector switch in Race mode is Red.

Each mode (SPORT – RACE) comes with 9 steps-programs so the driver can choose the one that suits his driving style (18 programs for manual transmission & 18 programs for automatic transmission in total).
This allows the driver to fine-tune each mode (SPORT – RACE)  according his needs by selecting one of the nine different programs on each mode.

You can select 1-9 in SPORT mode (Green light)  and 1-9 in RACE mode (Red light) with '1' being the least aggressive program and '9'  the most aggressive one.

Each program adjusts the response by 3-6%  so it can be fully adjustable and customized by each driver.

Pedal Lock Mode

The Pedal Lock mode provides extra protection against unauthorised vehicle use. The driver can deactivate the acceleration  ability of the vehicle when it's stationary through a 3 digit PIN. When Pedal lock is enabled the acceleration gets disabled and the vehicle stays on idle until you enter the correct PIN.

Valet Mode

The Valet mode limits the acceleration of the vehicle by 55 % - 65% - 75% (comes in 3 selectable levels). It is activated/ deactivated through a 3 digit PIN. By limiting the acceleration there will be a significant reduce in vehicle's performance (Power and Torque).


Sprint Booster modes and programs, are transmission type specific for better function
and performance.

The driver can select the type of his vehicle transmission through a slide switch located
on the right side of the selector switch. The device will automatically adjust the programs
according the type of transmission selected. There are 36 programs in total
(18 for manual transmission & 18 for automatic transmission).

Compact Size

The compact size allows the driver to place the selector switch anywhere on the dashboard with the use of the double sided tape.

Sprint Booster also offers the option to the driver to completely remove the switch from the device. In this case the device will work with the last settings stored in memory. For example , if the driver disconnects the selector switch while in SPORT-5 (SPORT mode- Acceleration program 5) , the device will keep as default the program SPORT-5.
