The MAP ECU is designed to be a piggy-back EMS for fuel control of larger injectors, upgraded turbochargers, and different camshafts. The MAP ECU converts the factory hotwire MAF signal into a speed-density based map, using an on-board 3 BAR pressure sensor. This is perfect for a street-driven cars with upgraded fuel and turbo systems. For more information, or for base maps and install diagrams, check out MAP ECU's website.
