Calibration Tables

Driver Requested Torque

Max Torque 0-2 Power Class 0-4

Location: Engine → Torque Management → Driver Demand
These tables serve as both a maximum torque limit and the main input into the driver requested torque calculation for a given RPM and Gear. Testing can be done to see which tables are used in a specific calibration or they can be made all the same for a consistent torque request.(More testing needed to confirm) Three sets of tables are present, one for automatic transmissions, one for manual, and one for Eco mode.

Torque Percent High / Low / Transmission

Location: Engine → Torque Management → Driver Demand
Lookup table for requested torque percent based on RPM and pedal percent. This percentage is applied to the max torque table. The output of this calculation is driver requested torque. Multiple tables are used depending on transmission type, vehicle speed, and sport mode selection.

Fuel Enrichment

Target Lambda at Full Load

Location: Engine → Fuel → Power Enrich
Values in this table are the target lambda while in full load enrichment. The x axis is engine RPM and the y axis is the time elapsed since meeting the conditions for full load enrichment. Many stock calibrations have this value set to stoich or near stoich and rely on Component Protection enrichment tables to provide extra fueling. Component Protection entry is controlled by the modeled value of exhaust components.

Power Enrichment Pedal Threshold

Location: Engine → Fuel → Power Enrich
This table serves as an entry point for the Target Lambda at Full Load table. When pedal percent is greater then the values in this table, Target Lambda at Full Load will be used for fueling.

Spark Advance

Location: Engine → Spark → Advance
Simos ECUs contain several spark tables broken into two main groups, Base and MBT. The car will attempt to run the values in the base spark tables before any modifiers (IAT, knock retard, learned adaptations).
MBT tables contain values that reflect ideal timing for Max Brake Torque. These values reflect an ideal situation not limited by environmental factors. The MBT values are also used in calculating delivered torque and therefore should be modified with caution.
Table selection is farther broken down by the state of the: Port flaps, Valve lift system, intake cam phase angle, exhaust cam phase angle. Cam angles are assigned an arbitrary number (0-2) using the VCT → Intake/Exhaust Cam Map tables.
