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.

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

DESCRIPTION
Activates PID regulator for idle control
PID regulator proportional term coefficient
PID regulator integral term coefficient
PID regulator derivative term coefficient
PID regulator positive integral windup limit
PID regulator negative integral windup limit
Maximum positive regulator influence on Duty Cycle value
Maximum negative regulator influence on Duty Cycle value
Minimum RPM error to start idle correction. When RPM is lower than
entered value, PID regulator is inactive.
