Introducing the COBB Accessport for Honda USDM (FC1/FC3) 2017-2020 Civic SI

The Accessport is the world’s best selling, most flexible, and easiest to use ECU upgrade solution for your Honda. Unlock power hidden within the vehicle by replacing conservative factory settings with more aggressive calibrations. Follow our staged upgrade path with pre-loaded Off The Shelf (OTS) maps or use custom mapping for any modification level. It’s the last engine management solution you’ll ever need.

Simple ECU flashing with gauge package! The in-cabin mountable Accessport V3 has a large, full color, high resolution screen which allows you to monitor up to six parameters in real time. Fully customizable from the look (multiple bezel colors), layout (set up race, street, or dyno gauge clusters), and mounting options (choose from 1,000s of standard vehicle mounts). And what are looks without brains? More processing power, memory, and storage to flash faster while saving all of your maps and logs. This is your new Accessport.

Included in the Accessport, also available for download on our website, are our COBB Off The Shelf (OTS) Maps. These files are generated by our COBB Calibration Team for otherwise stock cars. Components like replacement air filters for the stock airbox and exhaust components that retain factory catalytic converters are safe to use with these OTS Maps. The Stage0 file does not increase power as it retains all factory calibration data but provides the ability to utilize all of the other Accessport functions, such as data monitoring and logging.
