Description

Part #: 77-16802

Automobiles in the 21st century have replaced the more conventional throttle cable technology for an ECM (Electronic Control Module) that translates pedal travel into electronic signals in order to provide power to the wheels. The ETC system (Electronic Throttle Control), also known as drive-by-wire, has the unfortunate downside of delayed throttle response and subdued acceleration, creating problems in certain circumstances such as up-hill starts, quick gear changes, overtaking, etc. The Sprint Booster aims to overcome this throttle response delay for ETC-equipped vehicles, providing crisp on-tap acceleration at the driver's disposal. For vehicles with electronic control (ETC) systems, or drive by wire, this device plugs into the OE connector located behind the accelerator pedal. It's a simple installation, requiring no cutting of any wires or interference of the automobile's electronics. It does not affect other systems such as electronic injection, ABS, etc. The three main acceleration modes can be switched by pressing the main button. When the LED is off, the Sprint Booster is deactivated, and the car has factory settings. In Sport Mode, the LED is green, and throttle response is improved by up to 30%. With the red colored LED, the Sprint Booster is in Race Mode, and it improves response by up to 60%. Each acceleration mode comes with nine programs. Select 1-9 in SPORT mode and 1-9 in RACE mode, with '1' being the least aggressive program and '9' the most aggressive. The acceleration programs can be changed using the two arrow buttons on the top of the device. By selecting the desired acceleration program in each mode, the driver can fine-tune each mode per their driving style (e.g. select SPORT 9 & RACE 5).

MIA's Description

This compact plug-and-play module is designed to reduce the throttle lag common to electronic throttle control (ETC) systems, giving WRX drivers crisper, more immediate throttle response. The Sprint Booster from aFe modifies the throttle signal between the accelerator pedal and the engine control module to reduce perceived delay. It installs behind the accelerator pedal using the OEM connector — no wire cutting or permanent changes to vehicle electronics are required. The unit offers selectable Sport and Race modes with multiple program levels so drivers can tune response to their preference. Per manufacturer specifications, Sport mode can improve response by up to 30% and Race mode up to 60%; programs differ for manual and automatic transmissions to match behavior. Built-in Valet and Pedal Lock functions add configurable limits and protection using a three-digit PIN. The device is designed for WRX models 2012–2025 with H4 engines and is intended not to interfere with systems like electronic injection or ABS. This product is not currently CARB exempt and is not available for purchase in California or for use on any vehicle registered with the California Department of Motor Vehicles.
