Fuel choice affects performance: higher octane maps deliver the largest gains, while lower octane maps still improve throttle response, torque delivery, and overall drivability.
The Accessport reprograms your Subaru’s ECU with performance‑oriented maps, allowing you to increase horsepower and torque, log driving data, monitor real‑time parameters, and utilize tools like performance measurement and map switching.
Installation is simple and completely plug‑and‑play via the vehicle’s OBD‑II port. Guided on‑screen instructions walk you through the process, including flashing the ECU and selecting the appropriate maps.
Yes — the Accessport stores your original stock ECU calibration before any tune is applied. You can reinstall the stock calibration at any time, restoring the vehicle to its original settings.
Using the Accessport may be visible in ECU logs and could influence warranty decisions if a failure is directly related to the tune. It does not automatically void warranty, but dealerships can deny claims tied to tuned components. Always consult your dealer for specifics.
COBB’s OTS maps are designed for specific octane levels — use the map corresponding to the fuel you plan to run (e.g., 87, 91, or 93 octane). Higher octane fuels typically provide safer conditions for more aggressive timing and boost targets.
Yes — the Accessport supports custom tuning through COBB Accessport Manager and authorized COBB Protuner calibrations. While OTS maps provide performance gains on stock vehicles, custom maps optimized for specific modifications yield the best results.
COBB Tuning provides a limited warranty covering defects in materials and workmanship from the original date of purchase when purchased from an authorized dealer. This warranty does not cover damage from misuse, improper installation, or unauthorized modifications. Consult your reseller or COBB Tuning for complete warranty terms and conditions.
Warning! Installation of this Accessport over anything other than OEM or COBB software may result in ECU/TCU failure. Please contact COBB Support if you have any questions.
