A check engine light will be activated when actual boost exceeds the corresponding threshold in this table for a period of time as determined by the 'Boost Limit CEL Delay' table. As altitude increases, atmospheric pressure decreases, and the turbo must spin faster to maintain the same amount of boost, decreasing its efficiency. This table allows for a reduction in boost CEL limits as atmospheric pressure becomes progressively lower. When the boost limit CEL threshold is exceeded, the value in this table determines the delay before a CEL will be triggered. If boost does not exceed the threshold for the entire delay, then the CEL is NOT triggered and the delay is reset.

Multiplier

The function of this parameter is to reduce target boost as atmospheric pressure decreases keeping the turbo within its efficiency range. This multiplier is applied to the current atmospheric pressure and the 'Boost Comp Atmosphere Multiplier Offset' is added to the product. The resulting multiplier is limited to a range between 0 and 1 and then applied to target boost (absolute pressure).

Offset

This offset is involved in the calculation of a multiplier designed to reduce target boost as atmospheric pressure decreases. The value from the 'Boost Comp Atmosphere Multiplier Determination' table is first applied to current atmospheric pressure and then the offset is added to the product. The resulting multiplier is limited to a range between 0 and 1 and then applied to target boost (absolute pressure).

These are the starting values for wastegate duty. The ecu adjusts wastegate duty in an attempt to achieve target boost within the limits defined by the turbo dynamics and the initial and max wastegate tables. When wastegate duty is increased, this typically results in more boost, but with an increased chance of spiking. When wastegate duty is decreased, this typically results in less boost and a greater chance of not hitting boost targets. Wastegate compensation tables are applied to initial and max wastegate duty values.

This fuel map is used when the advance multiplier is greater than or equal to the threshold specified by the 'Fuel Map Switch (Advance Multiplier)' table. These values are used in open loop operation only and the air/fuel ratio is determined using the air flow data calculated from MAF sensor input. Because there is no feedback in open loop operation, the actual AFR may differ from the values in this table. In addition, the ECU applies a long-term A/F learning compensation to open loop fueling from patterns it recognizes in closed loop fueling which can cause further changes in the actual AFR. Other compensations to fueling exist as well. Because the underlying values of this table are enrichment values relative to stoichiometric, AFRs leaner than 14.7 cannot be chosen.

Instead, the negative correction is increased by the value in this table for each time period that passes with no knock as determined by the 'Feedback Correction Negative Advance Delay' table until feedback correction is zero.

When feedback correction is negative, this is the delay period over which if the knock signal is clear, the negative feedback correction will be incremented by the value in the 'Feedback Correction Negative Advance Value' table.

This is the minimum delay between possible individual increases in the current advance multiplier when the IAM is being re-evaluated. This is the initial ignition advance multiplier. The advance multiplier determines the percentage of the timing advance map to be added to base timing. Actual advance = (timing advance * (IAM/16)). This is a dynamic value that changes according to knock.

This is the initial change in the ignition advance multiplier (IAM) when re-evaluation of the IAM begins. When this starts, the IAM is reset to the 'Advance Multiplier (Initial)' value and the step value is added to or subtracted from this value depending on knock. The step value is reduced by half when, during this session, the IAM changes from increasing to decreasing, or vice versa. When the step value is less than or equal to 1 or the IAM hits 0 or 16 for a period of time, the IAM re-evaluation session ends. This how the ecu determines that the IAM has settled on the appropriate value.

When engine speed is the same or greater than the second value, the closed loop delay value is set to zero which can result in switching from closed loop to open loop depending on the current enrichment value as determined by the 'Open Loop Fueling' map. When engine speed drops below the first value, other specific closed loop triggers are reviewed. If all these triggers are below their thresholds, then the closed loop delay is determined from the 'Closed Loop Delay' table. In this case, assuming a non-zero delay value, the 'Closed Loop Calculated Load' and 'Closed Loop Throttle (Primary)' are used to determine the open loop to close loop transition and vice versa.

TABLE A TABLE B TABLE C TABLE D

This is the delay from closed loop to open loop. Only one of the four delay tables will be used depending on transmission type and other factors than can vary by rom. And only one of the four values from each table is used which depends on the time since the last engine start (first value in each grouping is the earliest range). If the delay is non-zero, the 'Closed Loop Throttle (Primary)' and 'Closed Loop Calculated Load' tables will be used to determine the transition from open loop to closed loop with the delay target determining the pause between the transition once either threshold is exceeded. If the delay is zero, then these tables will not be used and the closed loop to open loop transition will be decided by the current enrichment value as determined by the 'Open Loop Fueling' map.

If all these triggers are below their thresholds, then the closed loop delay is determined from the 'Closed Loop Delay' table. In this case, assuming a non-zero delay value, the 'Closed Loop Calculated Load' and 'Closed Loop Throttle (Primary)' are used to determine the open loop to close loop transition and vice versa. When the closed loop delay value is non-zero, this table will be used to determine the transition from closed loop to open loop and back again. When calculated load, (raw injector flow scaling x (engine load / 2)), rises above the threshold in this table, the process to exit closed loop begins. The current delay value is used to determine the pause in this transition to open loop. When calculated load drops below the threshold (and below a predetermined delta), fueling will transition from open loop to closed loop.

These are the alternative starting values for wastegate duty. The ecu adjusts wastegate duty in an attempt to achieve target boost within the limits defined by the turbo dynamics and the initial and max wastegate tables. When wastegate duty is increased, this typically results in more boost, but with an increased chance of spiking. When wastegate duty is decreased, this typically results in less boost and a greater chance of not hitting boost targets. Wastegate compensation tables are applied to initial and max wastegate duty values.

When the EGT is the same or greater than the second value, the closed loop delay value is set to zero which can result in switching from closed loop to open loop depending on the current enrichment value as determined by the 'Open Loop Fueling' map. When the EGT drops below the first value, other specific closed loop triggers are reviewed. If all these triggers are below their thresholds, then the closed loop delay is determined from the 'Closed Loop Delay' table. In this case, assuming a non-zero delay value, the 'Closed Loop Calculated Load' and 'Closed Loop Throttle (Primary)' are used to determine the open loop to close loop transition and vice versa. This is the delay from closed loop to open loop. Only one of these delay values will be used depending on transmission type and\or other factors than can vary by rom. If the delay is non-zero, the 'Closed Loop Throttle (Primary)' and 'Closed Loop Calculated Load' tables will be used to determine the transition from open loop to closed loop with the delay target determining the pause between the transition once either threshold is exceeded. If the delay is zero, then these tables will not be used and the closed loop to open loop transition will be decided by the current enrichment value as determined by the 'Open Loop Fueling' map.

When the engine load is the same or greater than the second value, a counter value is incremented. If engine load remains equal to greater than the second value, the counter will be continue to be incremented and if it exceeds the 'Closed Loop Engine Load Delay' value, the primary closed loop delay value is set to zero which can result in switching from closed loop to open loop depending on the current enrichment value as determined by the 'Open Loop Fueling' map. When engine load drops below the first value, the engine load counter value is set to zero and other specific closed loop triggers are reviewed. If all these triggers are below their thresholds, then the closed loop delay is determined from the 'Closed Loop Delay' table. In this case, assuming a non-zero delay value, the 'Closed Loop Calculated Load' and 'Closed Loop Throttle (Primary)' are used to determine the open loop to close loop transition and vice versa. This is the delay in clearing the primary closed loop delay value if engine load is greater than or equal to the value determined by the 'Closed Loop Engine Load' table.

When the closed loop delay value is non-zero, this table will be used to determine the transition from closed loop to open loop and back again. When calculated load, (raw injector flow scaling x engine load), is equal to or rises above the threshold in this table, the process to exit closed loop begins. The current delay value is used to determine the pause in this transition to open loop. When calculated load drops below the threshold (and below a predetermined delta), fueling will transition from open loop to closed loop.

When engine speed is the same or greater than the second value (by gear), the closed loop delay value is set to zero which can result in switching from closed loop to open loop depending on the current enrichment value as determined by the 'Open Loop Fueling' map. When engine speed drops below the first value (by gear), other specific closed loop triggers are reviewed. If all these triggers are below their thresholds, then the closed loop delay is determined from the 'Closed Loop Delay' table. In this case, assuming a non-zero delay value, the 'Closed Loop Calculated Load' and 'Closed Loop Throttle (Primary)' are used to determine the open loop to close loop transition and vice versa.

This table is used when the current gear is not being determined by the ecu, such as neutral. When engine speed is the same or greater than the second value, the closed loop delay value is set to zero which can result in switching from closed loop to open loop depending on the current enrichment value as determined by the 'Open Loop Fueling' map. When engine speed drops below the first value, other specific closed loop triggers are reviewed. If all these triggers are below their thresholds, then the closed loop delay is determined from the 'Closed Loop Delay' table. In this case, assuming a non-zero delay value, the 'Closed Loop Calculated Load' and 'Closed Loop Throttle (Primary)' are used to determine the open loop to close loop transition and vice versa.

When the closed loop delay value is non-zero, this table will be used to determine the transition from closed loop to open loop and back again. When throttle position is equal to or rises above the threshold in this table, the process to exit closed loop begins. The current delay value is used to determine the pause in this transition to open loop. When throttle position drops below the threshold (and below a predetermined delta), fueling will transition from open loop to closed loop.

When throttle position is greater than or equal to the selected value in this table, the closed loop delay value is set to zero which can result in switching from closed loop to open loop depending on the current enrichment value as determined by the 'Open Loop Fueling' map. When throttle position is less than the selected value, other specific closed loop triggers are reviewed. If all these triggers are below their thresholds, then the closed loop delay is determined from the 'Closed Loop Delay' table. In this case, assuming a non-zero delay value, the 'Closed Loop Calculated Load' and 'Closed Loop Throttle (Primary)' are used to determine the open loop to close loop transition and vice versa.
