Lambda control via label CYLBANK_CW
NOTICE
Engines with one lambda sensor (e.g. 4-in-a-row) run as 1-Bank-Systems. Set CYL-
BANK_CW to 0.
TIREVATH_FAK_x
Cylinder individual corrections. Set to 1.0 for first startup. Numbering refers to firing order!
INJOFFPATTERN
Torque reduction by injection fade out. Different, repeating fade out patterns can be
defined for several full power strokes of the engine (720° crank or 2 full rotations). This
prevents single cylinders from cooling down too much and makes it possible to find op-
timal patterns.
Example 4 cylinder engine:
The cylinders are assigned bitwise, the lowest bit represents cylinder 1 in firing order
(FO1), e.g. injoff = 1:
– First power stroke 0°‑720°: Cylinder 1 (FO1) is faded out.
– Second power stroke 720°‑1440°: Cylinder 2 (FO2) is faded out.
– Third Power stroke 1440°‑2160°: Cylinder 3 (FO3) is faded out.
– Fourth Power stroke 2160°‑2880°: Cylinder 4 (FO4) is faded out.
– Fifth Power stroke 2880°‑3600°: Cylinder 1 (FO1) is faded out.

Injection Start
TISTARTBASE
Base injection time for engine start. Can be set to a value near full load from the maps
TI_MIN/DEF/MAX in atmospheric engines. Scale down proportional to boost pressure for
turbo engines.
Further corrections: Predefined. If unsure, set to 1.0 for first start up.
