The dwell ignition system is a component of traditional ignition systems in internal combustion engines, responsible for controlling the timing of the ignition spark. It refers to the period during which the ignition coil is charged before the spark occurs, allowing enough energy to build up for a strong spark. The "dwell" time is measured in degrees of crankshaft rotation and is crucial for efficient engine performance. Proper dwell settings ensure optimal ignition timing and fuel combustion.

Dwell control is typically defined by the engine's ignition system. The dwell angle is the duration in crankshaft degrees during which the ignition points are closed. This setting affects the timing of the spark, influencing engine performance and efficiency.
electronic ignition on the 93, no controll. just set your timing.
A dwell meter is used to check the setting on a POINTS type ignition system, these have not been used in quite a few years, and for sure not as late as 1993.
A dwell meter measures the duration that the ignition points in a gasoline engine remain closed during each cycle, which is crucial for proper timing and efficiency. It connects to the ignition system and displays the dwell angle, typically expressed in degrees. As the engine runs, the meter indicates how long the points are closed, helping to diagnose issues with ignition timing and ensure optimal engine performance. Adjustments can be made based on the reading to achieve the correct dwell angle specified by the manufacturer.
The dwell angle on a 1968 Mustang with a 289 engine typically ranges from 28 to 32 degrees. Dwell refers to the amount of time the ignition points are closed during each engine cycle, affecting the timing and performance of the ignition system. Proper dwell adjustment is crucial for optimal engine performance, fuel efficiency, and smooth operation. Regular checks and adjustments can help maintain the engine’s efficiency and longevity.
timing: 5 degrees btdc. electronic ignition sets dwell automatically. timing: 5 degrees btdc. electronic ignition sets dwell automatically.
go with 27 on the dwell and 4 btdc on timing
Dwell angle is simply the amount of time the points or electronic ignition components are in a closed state to charge the primary side of the ignition coil for firing of the spark plug.. This time is expressed in distibutor rotation, hence the degrees..
to my knowledge 1980 Chevy v8 engines didn't have ignition points, and dwell settings are for points.
Cam dwell is: The number The number of degrees a cam rotates during the time the object controlled the cam does not move. The breaker points in the ignition system of a reciprocating engine are opened by a cam. The cam dwell, or cam dwell angle, is the number of degrees the cam rotates between the time the breaker points close and the time they open.of degrees a cam rotates during the time the object controlled by the cam does not move.

The dwell setting for a 1967 Mustang with a 6-cylinder engine typically ranges from 28 to 32 degrees. Dwell refers to the amount of time the ignition points remain closed, allowing the ignition coil to charge. Proper dwell settings ensure optimal engine performance and efficient ignition timing. It's important to consult the specific service manual for your vehicle for precise specifications.
