How does the AccessPORT work?
The AccessPORT overwrites portions of the stock ROM with modified table values called a map. These maps alter calibrations of different sensors as well as data lookup tables for a given set of modifications which allows the ECU to calculate fuel, ignition timing, cam advance, etc. appropriately. The OEM logic in the ECU remains the same, which means that all of the intelligence, sophistication and driveability of the factory ECU is retained and optimized to extract additional power from modifications.
