Allows the ignition timing of each individual cylinder to be adjusted independently. This feature can be used to help balance individual cylinder temperatures or correct individual timing irregularities caused by inaccurate trigger setups.
The individual cylinder ignition trim runtime values show the current table trim value and can be views on the Ignition tab of the runtime value window (F12 key).
Individual Cyl Ign Trim Settings:
The following options are available:
·OFF - All cylinders receive the same ignition timing.
·Single - Each cylinder can be adjusted to receive slightly more or less ignition timing over the entire operating range, enter the number of degrees trim for each cylinder in the Individual Cylinder Ignition Trim Table. A value of 0 indicates no trim.
·Table - Each cylinder can be allocated a 3D table. The tuner can decide if each cylinder will have its own table or if groups of cylinders will share tables. Up to twelve tables are available for individual ignition timing adjustment.
·Table Disabled - All cylinders receive the same ignition timing but the tables stay allocated and visible.
Individual Cylinder Ignition Trim Table
Used to specify the amount of trim to be constantly applied to each cylinder. A positive number will advance the cylinder, a negative number will retard the cylinder and a value of 0 will not change that cylinders timing.
Only available when Indiv Ignition Mode is set to Single.
Only available when Indiv Ignition Mode is set to Table.
Used to specify which Ignition Trim Table each cylinder will use.
Cylinders can be allocated to tables in pairs, groups or individually.
e.g. 4 Cylinder Engine - individual tables
Cyl1 Allocation = Cyl1 ITrim Table
Cyl2 Allocation = Cyl2 ITrim Table
Cyl3 Allocation = Cyl3 ITrim Table
Cyl4 Allocation = Cyl4 ITrim Table
e.g. 4 Cylinder Engine - paired tables
Cyl1 Allocation = Cyl1 ITrim Table
Cyl2 Allocation = Cyl2 ITrim Table
Cyl3 Allocation = Cyl2 ITrim Table
Cyl4 Allocation = Cyl1 ITrim Table
e.g. 6 Cylinder Engine - grouped tables
Cyl1 Allocation = Cyl1 ITrim Table
Cyl2 Allocation = Cyl2 ITrim Table
Cyl3 Allocation = Cyl1 ITrim Table
Cyl4 Allocation = Cyl2 ITrim Table
Cyl5 Allocation = Cyl1 ITrim Table
Cyl6 Allocation = Cyl2 ITrim Table
Link G4X ECUs have the ability to provide each cylinder with it's own specific ignition trim regardless of ignition trim regardless of number of cylinders or ignition mode (provided the trigger pattern provides full sync). Waste Spark, Distributer, direct spark etc can all trim each cylinder individually.
Cylinder Allocations can be grouped to suit the application (one table per bank or other variations) or each cylinder can be allocated it's own table. Cylinders not allocated a table will not have a trim applied to them.
