11.6 Common ignition-based timing
General remark on ignition angles
Ignition angles of all cylinders (Par. 13550-13565) are worked out by the addition of 3
terms:
the common ignition base timing (Par. 3911-3913) -> This paragraph
the common ignition timing offsets (Par. 3917, Par. 3918) ->
11.7 Common
Ignition timing offsets
the cylinder individual ignition angle offsets (Par. 13450-13515) ->
11.8 Cylinder
individual ignition angle offsets
These angle offsets are internal configured values and external knock retards
Ignition angle [cyl] = common base timing + common timing offsets + cyl individual angle offsets [cyl]
Ignition angles and timings are always given in terms of [° crank] before TDC,
so positive angles are before TDC, negative angles after TDC. The ignition an-
gles are limited in 2 steps. First the common ignition timing (common base tim-
ing + common timing offsets) will be limited in a range of [-10; 90°] before
TDC. Additionally the final ignition angles (common ignition timing + cyl. In-
dividual angle offsets) will also be limited in a range of [-10; 90°] before TDC
The common ignition base timing can be:
a fix value
the result of up to 2 different speed- and load-dependant ignition timing maps
Which setpoint is currently active is displayed in parameters 3914-3916:
Par. 3914 = 1 -> the fix common ignition base timing is active
Par. 3915 = 1 -> the common ignition timing map 1 is active
Par. 3916 = 1 -> the common ignition timing map 2 is active
11.6.1 Fix common ignition base timing
To setup fix common ignition base timing, perform following configuration:
Par. 5910 = 0
Par. 1910 = desired ignition timing [° crank before TDC], for example,
