Up to +57 HP & +89 lb-ft at the wheels — real dyno-proven gains on the 2022+ WRX (Stage 2, 93 octane) over stock, with the pump-gas-friendly Stage 1 still adding meaningful power.
The world's best-selling ECU upgrade — pre-loaded Off-The-Shelf (OTS) maps let you unlock hidden power in minutes, no laptop or tuner visit required.
50-state emissions legal — carries a CARB Executive Order (EO# D-660-225), so it's legal for street use in all 50 states when used per COBB's application guide.
Full-color in-cabin gauge display — monitor up to six live parameters (boost, AFR, timing and more) with race, street, or dyno gauge layouts.
Flex Fuel & custom tuning ready — store up to 100 maps, run custom Protuner calibrations, data-log, read/clear codes, and revert to stock any time.
Fits 6MT & CVT, 2022-2026 WRX — one Accessport covers the whole VB generation (2026 map support rolling out; Flex Fuel not yet available for 2026).
The COBB Accessport V3 replaces conservative factory settings with proven, aggressive calibrations — the last engine management solution your 2022+ Subaru WRX will ever need.
Simple ECU Flashing With a Gauge Package
The in-cabin mountable Accessport V3 has a large, full-color, high-resolution screen that lets you monitor up to six parameters in real time. It's fully customizable — from the look (multiple bezel colors and interchangeable faceplates), to the layout (race, street, or dyno gauge clusters), to the mounting (choose from thousands of vehicle-specific mounts).
Under the hood it packs more processing power, memory, and storage so it flashes faster while saving all of your maps and logs. Follow COBB's staged upgrade path with pre-loaded OTS maps, or run a custom Protuner calibration for any modification level.
