DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Brief description: Notes
Saab Trionic T7 LEV is an engine management system (control module) that regulates air mass, fuel and ignition.
For information concerning the available variants, see BRIEF DESCRIPTION
As the driver depresses the accelerator pedal, the accelerator cable turns the pedal position sensor located in the throttle body. The system requests a torque and the throttle motor turns the throttle until the throttle position sensor value corresponds with the requested value. The charge air volume is also increased if necessary. The system has the following advantages:
- Turbo lag can be compensated.
- Emissions can be reduced in connection with load changes.
- Integrated idle speed control.
- Load compensation possible throughout the whole load and speed range.
- Efficient torque limitation as necessary.
- Cruise control easy to integrate.
Fuel injection is sequential and is controlled by the air mass flow.
Ignition is performed by an ignition discharge module. The spark plugs are used as sensors to detect combustion and knocking. This means that neither a camshaft position sensor nor a knock sensor is required.
Saab Trionic T7 has been developed by Saab and has great development potential.
The following functions have been added compared with the earlier Trionic T5 system:
