Calibration Bulletin:
The Mazdaspeed3 / Mazda3 MPS / Mazdaspeed Axela ECU has implemented logic that will significantly increase fueling to the engine once the DI Fuel Pressure drops below ~1600psi. This logic is intelligent by design, but also puts excessive demands on the fueling system and further forces the DI Fuel Pressure to drop well below safe or effective levels. This new logic combined with an inadequate factory Camshaft Driven Fuel Pump (CDFP) results in the following.
