Dwell:

When using in dwell controlled systems (i.e. non-CDI) the following guidelines should be used:

·

Target a base dwell time of 3mS and 

only

 increase it when needed due to high cylinder pressures. 

·

The maximum individual coil dwell “ON” time must not exceed 9mS at any time, regardless of engine
RPM.  Exceeding this time will cause the coil to overheat and fail.

·

For continuous duty the maximum “ON” time must remain below 40% duty (on 40% of the time, off 60%
of the time). Exceeding this will cause the coil to overheat and fail.

·

For short bursts, the coil dwell can go as high as 80% “ON” duty but these forays need to be short (under
5 seconds or so) and cannot be frequent.
