The AccessPORT relies on the powerful AccessECU technology to perform the task of reprogramming the factory ECU for high performance applications. By fully reverse engineering the factory ECU in-house, we are able to not only modify all the fuel, ignition timing, and boost maps but also re-engineer critical parts of the software for improved performance and consistency. Out unsurpassed understanding of the factory ECU allows us unlimited control and creativity to provide you the very best ECU programming available.
