BMW 550i Gran Turismo 4.4 ECU mapping – 3133

The BMW 5 series 550i Gran Turismo 4.4 is a massively powerful car, but that doesn't mean you can't have more! The V8 engine has got lots more to offer than BMW let you have. Prindiville tuning offers a simple performance ECU remap which boosts mid-range torque and adding a sizeable BHP when used in conjunction with our sport exhaust system. In addition, it remaps the fly-by wire throttle to improve responsiveness for faster bursts of acceleration. Prindiville ECU tuning will give your vehicle greater fuel efficiency and improved drive-ability that BMW 5 series 550i Gran Turismo 4.4 drivers look for.

Up to 20% more power and 20% more torque are impressive values. Improved torque in connection with increased power guarantees enhanced drive at a reduced number of revolutions.

This provides a higher level of control and safety in many traffic situations, particularly when increased power is needed quickly.

How does it work?

The Prindiville power enhancement modifies the injection system by fine-tuning the duration of the injectors. This is achieved by blue printing the original characteristics and intercepting the electronic signals from the ECU to the injection system. The fuel injection and engine speed are recorded and recalculated to optimize performance.
