STEP 1
ACCESSPORT
The COBB Tuning Accessport is the first and easiest modification you can make to your car to see instant results. How does it work? Each car has an engine control unit. The ECU software's job is to manage the multitude of signals from your engine, then make adjustments to parameters such as air/fuel ratio, ignition timing, and boost to make the engine run optimally. Learn more in this video where we walk you through the basics of the Accessport and some of its features., designed to improve the driving experience.

STEP 2
STAGE POWER PACKAGES
Our engineers rigorously test Hard Parts to find the right order and combination for the best incremental power gains. Maps are created and tested to tune the ECU so that it supports and takes advantage of each part. With these results, COBB is able to create the Upgrade Path of Staged Packages that have all the necessary parts to upgrade your car. Learn more about this process in this video.

STEP 3
CUSTOM TUNING
So what is a custom tune? Custom tuning means fine tuning an existing COBB Off the Shelf Map or creating a new map from scratch, to gain the maximum performance for your set up. You can do all this and more with a Protune.
THE COBB WAY
With over 22 years of Research and Development, COBB Tuning has created Upgrade Paths designed to provide you with everything you will need to go from a bone stock car to a powerful, drivable, daily smile-making machine. Each path is specifically designed to maximize power of the Accessport, Hard Parts and our Off-The-Shelf maps.
