What will BSR tuning change?

Description of Trionic T7
T7 was creates by Saab and is very different from other systems (such as Bosch). The system controls air mass, fuel and ignition. T7 uses an air mass meter, MAP sensor and electronic throttle.
When the driver accelerates the system requests a torque and the throttle engine adjusts the throttle to obtain the desired torque. When necessary the amount of boost air is increased.
The fuel injection is sequential and is controlled by the air mass flow. The ignition uses an ignition cassette. The spark plugs are used as sensors to detect combustion and knocking.



General description of changes/inspections performed.
BSR adjusts approx. 60 Trionic 7 system functions.

FunctionMeasures
Ignition Calibration
(Ignition Calibration)		Optimised for best performance and to comply with exhaust emission requirements. Even with regards to exhaust emissions temperature. Possible knocking tendencies are eliminated.
