Engine – Ignition Coils

Figure: Engine – Ignition Coils

Ignition Coil Type

Select the ignition coil type from the drop-down list. (Without this selection the configuration cannot be downloaded to the MIC5.)

 

Only use measured ignition coils

To operate the MIC5, only ignition coil types measured by MOTORTECH may be used. All ignition coils used must correspond to the part number selected in the drop-down list. Different coil types must not be mixed and also no equivalent or replacement types may be used.

If a coil type used is not in the drop-down list, then the MIC5 is currently not used.

 

Secondary Diagnostics Enabled

The secondary diagnosis can be deactivated and activated for ignition coils that support this function. If the ignition coil does not support this function, the secondary voltage estimation calibration and the of the secondary short calibration are not available.

Secondary Voltage Estimation Calibration

A correction value without units can be set for the secondary voltage estimation for every configured output to increase the accuracy of the secondary voltage estimation for each individual cylinder. This allows, for instance, different cable lengths on the engine to be compensated.

The values of the secondary voltage estimation can be changed for each individual cylinder. The value range depends on the ignition coil. 0.0 is set as the standard value for all cylinders. You can adjust the secondary voltage estimation while the engine is running in the runtime adjustments (refer to Runtime Adjustments – Secondary Voltage Calibration).

Secondary Short Detection Calibration

The starting voltage and the secondary short detection sensitivity can be adjusted. You can adjust the secondary short detection in the runtime adjustments while the engine is running (refer to Runtime Adjustments – Secondary Short Calibration).

Secondary Short Enable Voltage

Set the average ignition voltage required to activate the secondary short-circuit monitoring:

Secondary Short Sensitivity

The permitted value range depends on the set ignition coil.

Set the sensitivity of the short-circuit detection e.g. as follows:
