DBW Idle range
Idle valve min DC Minimum allowed signal Duty Cycle for PWM valve
Idle valve max DC Maximum allowed signal Duty Cycle for PWM valve
Idle corr. analog input
Defines which analog input is used to read and calculate correction
value for idle device Duty Cycle. Correction value is defined in Analog
in corr. table
PID control
Idle PID control parameters are used to configure idle RPM PID regulator. Regulator is designed to
keep engine RPM at level defined in Idle Target RPM table. Regulation is based on values from
Idle Ref table. Is is possible to use simplified regulator based on DC error correction map.
Information about idle control state (active or not) and controller parameters can be found in Log
group idle.
ATTENTION !
Fine tuned VE table in idle range is a groundwork for idle tuning.
PARAMETER DESCRIPTION
Enable PID control Activates PID regulator for idle control
kP PID regulator proportional term coefficient
kI PID regulator integral term coefficient
kD PID regulator derivative term coefficient
Integral limit + PID regulator positive integral windup limit
Integral limit - PID regulator negative integral windup limit
Max feedback + Maximum positive regulator influence on Duty Cycle value
Max feedback - Maximum negative regulator influence on Duty Cycle value
Deadband RPM
Minimum RPM error to start idle correction. When RPM is lower than
entered value, PID regulator is inactive.
