Idle Ign. Correction; Idle Rpm Ref; Idle Ign Cut; Idle Ign Vs Clt - ECU Master EMU User Manual

Idle ign. correction

Idle ign. correction is used to define ignition angle correction as a function of RPM error (difference
between current RPM and target RPM). Target RPM can be set in Idle Target RPM table. Idle
control by ignition angle change is activated in Idle ignition control options.

Idle RPM ref

Idle RPM ref table is used to define idle valve Duty Cycle as a function of engine RPM. Values from
the table are executed only when Idle control is not active.

Idle IGN cut

Idle ign. cut table is used to define ignition event cut percent as a function RPM error (difference
between current RPM and target RPM). Target RPM can be set in Idle Target RPM table. Idle
control by ignition cut is activated in Idle parameters by setting Idle valve type as Ignition cut.

Idle IGN vs CLT

Idle ign. vs CLT is used to correct ignition angle as a function of engine Coolant Temperature
(CLT). Function is only active when idle RPM's are being controlled (Idle control active).

Analog in corr.

Analog in correction table is used to regulate Duty Cycle of idle valve in relation to analog input
voltage. Function can be useful to manually change idle with potentiometer. Analog input to be
used is set up in Idle parameters (Idle corr. analog input).

DC error correction

DC error correction table is used to set idle valve Duty Cycle correction as a function of RPM error
(difference between current RPM and target RPM). Target RPM can be set in Idle Target RPM
table.
