Injectors

• Injector Flow Rate Low: Injector Flow Rate for low commanded fuel mass values.
• Injector Flow Rate High: Injector Flow Rate for high commanded fuel mass values.
• Injector Flow Rate High Mult vs. Pressure: Injector flow rate multiplier used to compensate injector flow rate for fuel pressure differences.
• Injector Flow Rate Low Mult vs. Pressure: Injector flow rate multiplier used to compensate injector flow rate for fuel pressure differences.
• Injector Breakpoint: The commanded fuel mass at which the injector flow rate switches between the Low and High flow rate values. This value also offsets the calculated InjPW when using the Flow Rate High value.
• Injector Offset vs. Voltage: Injector Offset in relation to ignition voltage. This value adds to the injector pulsewidth.
• Injector Offset vs. Pressure: Injector Offset multiplier in relation to pressure. This value multiplies the injector offset.
• Injector Timing vs. ECT: This table is used to change the injector timing in relation to ECT. Values are in crankshaft degrees.
• Injector PW Minimum: Minimum injector pulse width.
• Injector Pressure Drop Reference: The reference pressure across the fuel injectors.
• Injector Intake Valve Open: This is the crank angle that the intake valve opens.
• Injector Spray Delay: The time it takes for the fuel to travel from the injector to the inlet valve.
• Injector Engine Soak Time Enrich vs. Soaktime vs. ECT: This table compensates for hot fuel components during restart based on the time since the engine was shut down and ECT.
• Injector Engine Run Time Enrich vs. Time vs. Airflow: This table compensates for hot fuel components during restart based on Engine Run Time and Airflow.
• Injector Hot Enrich vs. IAT vs. Rail Temp: This table compensates for hot fuel components during restart based on IAT and the calculated Fuel Rail Temperature.

COT

• Cat Temp Control: Master enable/disable for Catalytic Converter Protection system. Richens fuel to cool cats.
• COT Stage 1 Temp: Catalyst temperature that stage 1 COT becomes active.
• COT Stage 2 Temp: Catalyst temperature that stage 2 COT becomes active.
• Flange Temp Control: Master enable/disable for Exhaust Manifold/Flange Protection system. Richens fuel to cool exhaust manifold.
• Flange OT Enable Temp: Exhaust flange temperature that flange temp control becomes active.
• O2 Temp Control: Master enable/disable for O2 Sensor Protection system. Richens fuel to cool O2 sensors.
• O2 Sens OT Enable Temp: O2 sensor temperature that O2 sensor temp control becomes active.
• Exhaust Temp Mode vs. Airflow: This Mode # is used to lookup other tables in the exhaust component temperature calculations.
• Exhaust Temp vs. RPM vs. Load: This is the estimated exhaust temperature used in the exhaust component temperature calculations.
