Xineering Downshift Blip Module Kit WRX / STI / BRZ | USB Programmable | Performance Throttle Control
Overview
The Xineering Downshift Blip Module Kit is designed for Subaru WRX, WRX STI, and BRZ/FRS/86 owners seeking precise, consistent rev-matched downshifts without the need for heel-to-toe technique. This module automatically blips the throttle during downshifts by detecting brake and clutch inputs, delivering a smooth and confident driving experience on both street and track. Built specifically for drive-by-wire (DBW) manual transmission vehicles, it integrates seamlessly with your factory throttle pedal and clutch/brake switches.
Engineered with a focus on reliability and ease of use, the Xineering module simulates throttle pedal input without overdriving the signal, ensuring compatibility with OEM and aftermarket ECUs alike. Its USB programmability allows fine-tuning of throttle blip percentage, duration, and timing to match your driving style and vehicle setup. The sealed enclosure and OEM-style harnesses maintain factory-level quality and durability, reflecting Xineering’s commitment to precision engineering and user-friendly design.
For Subaru enthusiasts, this downshift blip module enhances driving dynamics by reducing shift shock and improving corner entry confidence. It eliminates the learning curve of heel-toe downshifting, making spirited driving more accessible while preserving clutch and transmission longevity. Whether on road race circuits or spirited street drives, this kit delivers a refined, connected feel that complements Subaru’s performance heritage.
