This new logic combined with an inadequate factory Camshaft Driven Fuel Pump (CDFP) results in the following.
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. 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. They can be easily found at Calibration Bulletin:

Seek the help of a COBB Accesstuner professional should your Mazdaspeed3 / Mazda3 MPS / Mazdaspeed Axela fall outside of Stage configurations. Doing so will result in much higher than desired boost levels. COBB OTS mapping is NOT designed to be used with upgraded aftermarket wastegate (boost) actuators.Regardless of what the manufacturer may suggest. As such, if you choose to use an intake other than the COBB SF Intake you MUST have it properly calibrated. Using a Calibration with an intake other than the one it was designed for will cause engine damage.These settings can be adjusted with our Accesstuner software.įaster datalogging means more resolution in data logs, allowing users to see how the engine is behaving during high-speed and high-load conditions in greater detail. Flat-Foot Shift allows the user to maintain wide-open-throttle during gear changes, keeping partial boost between shifts and improving acceleration post-shift. Launch Control limits engine RPM to a user-set value when launching to build boost and increase launch consistency. Launch Control and Flat Foot Shifting has been enabled for all Mazdaspeed3 / Mazda3 MPS / Mazdaspeed Axela vehicles. Breakpoints in the load axes can be set at user defined values, allowing the tuner to increase table resolutions in areas where it is needed, and decrease table resolution in less critical areas of the table. The load scaling table axes are now completely customizable up to 5.0 grams of Load. V234 calibrations and higher employ this form of simplified boost control logic.ĬOBB Tuning’s implementation of Dynamic Load Scaling allows tuning beyond the OEM limitation of 2.0 grams of Load while retaining high table resolution.
