Fuel Trims
WallWetting
Units: Throttle Rate vs EngineSpeed vs MassAirflow Adder
Description: This table adds additional fuel enrichment for acceleration conditions. This is
mostly used to help the engine accelerate well and avoid a lean condition that can occur when
the throttle is opened quickly at low RPM.
WallWetting2
Units: Throttle Rate vs CoolantTemp vs MassAirflow Adder
Description: This table adds additional fuel enrichment for acceleration conditions when the
engine is cold. Both tables (WallWetting and WallWetting2) are added together.
The output of each wall wetting table is added together. This effectively adds another tuning
variable dimension since the y-axis of each table does not need to match. For example if
compensation is required as a function of engine speed, throttle rate AND coolant temperature,
the tables can be configured as above to satisfy the tuning requirements.
