What will BSR tuning change?

General description of changes/inspections performed by BSRs Motronic chip.

FunctionMeasures
Ignition
(Ignition calibration matrixes)
Optimised for best performance and to comply with exhaust emission requirements, even with regards to exhaust emissions temperature. Possible knocking/pinging tendencies are controlled and adjusted.
Fuel
(Fuel calibration matrixes)
Optimised for best performance and to comply with exhaust emission requirements. Exhaust emissions temperature control>
Boost Calibration
(Boost Calibration matrixes)
Adapted to increased power and adjusted for required character.
Boost valve control
(Boost valve duty cycle calibrations)
Regulated for appropriate boost pressure build-up and to eliminate possible boost pressure spiking.
Boost Calibration Limit
(Boost level safety limit)
Adjusted for maintained safety.
Torque Gear Limit
(Torque limit for each gear)
Regulated for optimum acceleration without exaggerated wheel spin, still maintaining safe transmission.
E-gas (Drive by wire)
(Drive by wire calibration)
Adjusted for improved fuel response
Max Vehicle Speed Calibration
(Speed limit)
Eliminated.
Max Engine Speed Calibration
(Engine RPM limit)
No alteration.


Some models do not have all the above mentioned features, and there may be other differences depending on model and make of the car.
