Timing – Schedule A – General

Figure: Timing – Schedule – General

Limits

Enter the limits of the timing point at which the ignition can fire. The timing points of the outputs will be limited to this range relative to the respective top dead center of the pertinent cylinder. The global timing can then not be shifted beyond this range by any adjustments.

Base Timing

Enter the timing specified by the engine manufacturer. This point must be within the limits entered and is a static portion of the global timing.

Analog Current Input

The analog current input can be enabled and disabled by clicking. Enter the values by which the adjustment is to be implemented for the corresponding input signal. An error value can be entered for the signals if a failure threshold has been defined for the corresponding input in the window Timing – Analog Inputs. If the signal is below the failure threshold, the timing is offset by the error value. The adjustment remains until the signal again exceeds the threshold to reset the error state (see Timing – Analog Inputs).

Speed Curve

The speed curve can be activated and disabled by mouse click and offsets the timing depending on the speed. A max. of eight speed points are available. If you select a number of points from the list, the corresponding number of fields is activated for input.

The first speed point is always set to 0 RPM. All other timing points are assigned with the value by which the signal is to be offset when the respective speed is reached. For the last speed point, the timing of the nominal speed should be entered. Please note that the speed points must always be entered in ascending order.
