Actual dwell time used will depend on the current system voltage with higher voltages having lower dwell times and vice versa. See section below on voltage correction -- Cranking dwell - The nominal dwell time that will be used during cranking. Cranking is defined as being whenever the RPM is above 0, but below the 'Cranking RPM' values in the [Cranking](Cranking "wikilink") dialog +- Cranking dwell - The nominal dwell time that will be used during cranking. Cranking is defined as being whenever the RPM is above 0, but below the 'Cranking RPM' values in the [Cranking](/en/configuration/Cranking "wikilink") dialog - Running dwell - The nominal dwell that will be used when the engine is running normally. - Spark duration - The approximate time the coil takes to fully discharge. This time is used in calculating a reduced dwell when in time limited conditions, such as mentioned above on single coil, high cylinder count engines. The limited dwell time is calculated by taking the maximum revolution time at the given RPM, dividing by the number of spark outputs required per revolution and subtracting the spark duration. Outside of those conditions, this setting is not used. - Over dwell protection - The over dwell protection system runs independently of the standard ignition schedules and monitors the time that each ignition output has been active. If the active time exceeds this amount, the output will be ended to prevent damage to coils. This value should typically be at least 3ms higher than the nominal dwell times configured above in order to allow overhead for voltage correction.
