Sprint Booster V3 Throttle Control Honda Civic Si 2012-2015

The Sprint Booster V3 is a throttle response controller made for the 2012-2015 Honda Civic Si, the ninth generation car with the 2.4L four-cylinder, in both coupe and sedan form. The Si uses an electronic throttle, so the pedal sends a signal to the engine computer rather than pulling a cable. Honda calibrates that signal for smoothness, which is why the Si can feel soft in the first part of the pedal stroke even though the 2.4L pulls hard once it is on the cam.

What it does on the Civic Si

The Sprint Booster sits between the pedal and the engine computer and delivers a faster, stronger version of the pedal signal. The throttle opens sooner, so the car reacts the instant you press. With the six-speed manual, rev-matched downshifts are easier to time and the car pulls more eagerly out of slow corners. Power is not increased and the fuel and ignition maps stay factory, so the change is in how quickly the Si reaches the power it already makes. The difference is clearest at low and mid rpm, where most street driving happens.

Construction and installation

The V3 is application-specific hardware with the connectors matched to the Honda pedal plug. It installs at the accelerator pedal in minutes with no cutting, splicing or tuning software. A small pendant mounts within reach and shows the active program on a digital display, letting you change between Off, Sport and Race while driving. Unplug it and the Civic is back to stock.

Features

• Three driving modes selected from the pendant: Off (factory response), Sport (green) and Race (red)
• Nine steps in Sport and nine in Race, with 36 programs in total across manual and automatic calibrations
• Valet mode limits available acceleration to 55, 65 or 75 percent
• Pedal Lock mode blocks the throttle as an anti-theft measure
• Compact V3 housing with a digital program display
• Plug-n-play connection that unplugs to return the car to stock
• Winner of the SEMA Best New Performance Street Product award

What’s Included

• One Sprint Booster V3 control unit (vehicle-specific plug-n-play connectors, pendant switch)
