FAQ
What is the AP3-POR-021?It is a vehicle-specific COBB Accessport V3 package that combines ECU calibration, live gauge monitoring, data logging, and diagnostic functions in a handheld device.
Does this fit every Porsche model listed in the title?It fits only the exact model years, transmissions, markets, and trims shown in the Fitment table. The listed exclusions remain outside the verified application.
How many gauges can the display monitor?The high-resolution color screen can display up to six selected parameters at once.
Can the original ECU calibration be restored?Yes. The installation process stores the original calibration so the vehicle can be returned to stock when appropriate.
How many map files can the device store?COBB specifies storage for up to 100 map files.
Is the display permanently mounted?No. The package includes a vehicle mount and cradle, and the handheld device can be removed from the vehicle.
Can it be installed over another company's engine software?No. COBB warns against installing the Accessport over non-OEM or non-COBB engine software. Return the vehicle to a supported calibration first.
Is this product emissions legal?COBB lists the application under CARB EO D-660-267, supporting 50-state sale and use for the exact verified applications.
What should be checked before installation?Confirm the exact year, model, trim, transmission, market, battery condition, and current ECU software before connecting the device.
Installation Instructions
- Confirm the vehicle year, model, trim, transmission, and US-market application against the Fitment table before opening the package.
- Verify the package label and manufacturer part number AP3-POR-021, then confirm that the vehicle is running supported OEM or COBB engine software.
- Connect an appropriate battery charger and switch off unnecessary electrical loads so voltage remains stable throughout ECU communication.
- Connect the supplied cable to the vehicle diagnostic port and the Accessport, then follow the on-screen installation prompts without disconnecting power.
- Select only a map that matches the vehicle's hardware, fuel, and exact configuration. Do not substitute a map for a related model or trim.
- Allow the device to save the original calibration and complete programming before cycling the ignition as directed.
- Start the vehicle, check for warnings or diagnostic codes, and verify normal operation before driving.
- Configure gauges and alerts for the parameters appropriate to the selected calibration, then secure the mount where it does not obstruct visibility or controls.
- Retain the original calibration and package information for future updates, troubleshooting, or return-to-stock procedures.
