Cobb Accessport V3 for Mazda Mazdaspeed3
This Accessport V3 allows for simple computer flashing, featuring map switching, real-time gauge displays, and data logging capabilities.
The Cobb Accessport V3 features a large, full-color, high-resolution monitor that lets you check up to six parameters in real-time.
High processing power and large memory storage enable fast flashing while saving maps and logs.
Note: Installing the Cobb Accessport on anything other than the factory computer may result in ECU/TCU failure.
Features
- Large, full-color, high-resolution monitor
- Customizable multi-gauge display
- In-vehicle mount with on/off switch
- Simplified functionality for faster and easier use
- Advanced Tuning Settings - Configure performance features such as Launch Control, Flat Foot Shifting, and Wastegate Duty Cycle directly from the Accessport. Simply enable the "Advanced Tuning Settings" feature to access these options.
- Launch Control - Launch Control generates boost to provide instant power upon takeoff. Once enabled, these settings can be adjusted every time a compatible map is flashed.
- Flat Foot Shifting - Allows you to shift gears while keeping the accelerator pressed, reducing shift lag and boost lag. Once enabled, these settings can be dialed in via the Accessport before a compatible map is flashed.
- Wastegate Duty Cycle - Adjust the wastegate duty cycle during flashing (-50% to +10%) to compensate for underboost, overboost, and boost cut conditions (COBB OTS map required).

Before Ordering
〇 Regarding Import Consumption Tax
At the Shaftoya shopping site, we cover the import consumption tax incurred at the time of import, so there will be no additional charges beyond the total amount paid at checkout.
〇Checking Compatibility
Our entire product database is based on North American vehicles (USDM). Please confirm compatibility with Japanese domestic vehicles (JDM) before ordering. (If you are unsure whether a listed product is compatible with your vehicle, please feel free to contact us. Our support team will be happy to investigate for you.)
If you order without confirming compatibility, we cannot accept returns due to incompatibility.
Please note that even if items are sorted by selecting the year, manufacturer, and model on our homepage, it does not necessarily mean they will fit Japanese models without modification.
All products have been translated into Japanese using translation software. As there may be confusing expressions, please contact us before ordering if you have any questions.
○ Regarding Shipping
Shipping costs are paid at the time of settlement. Estimates for shipping can be calculated automatically by entering your shipping address on the checkout page. For large items such as body parts, the automatically calculated shipping cost may occasionally differ significantly from the actual cost. In such cases, we will contact you individually via email.
All products are generally shipped internationally from our U.S. warehouse. Unlike domestic shipping in Japan, international shipping takes approximately 7 to 14 days, so please allow ample time for delivery. If you are in a hurry, please contact us in advance to confirm the delivery date. All products are transported via air freight; they are not shipped via sea freight.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
Please note that all products we handle are designed and manufactured outside of Japan. They are not compliant with the "Japanese vehicle inspection system," and we cannot provide documents such as strength calculation reports for Japanese inspections. Therefore, all parts are sold for the purpose of "use on circuits, private land, or off-road," and installation and use are at your own risk.
○ Regarding Warranty
Please check the contents immediately upon arrival. As all products are shipped internationally from outside Japan, there may be shipping damage to the packaging box or the product itself. We will only provide returns, refunds, or replacements for shipping-damaged items, defective products, or incorrect items if notified within 7 days of receipt. Please understand that we only provide warranty support for products sold through us. We do not provide support through other companies or distributors located in Japan.
