Dwelling upon the ignition (pun intended)
I've noticed in many different places that people tend to write things like:
IF you are using VB921s for direct coil control, THEN you must configure dwell. (emphasis is mine)
This seems to imply
that if you are NOT
doing direct coil control (retaining the igniter) THEN
you do not have to configure dwell. This is technically a false negation, but it still strongly suggests that the normal course of action would not involve configuring dwell.
I've observed (by comparing IGN trigger to coil primary current) that on a 1.6 anyway, the igniter is just a simple switch, and that dwell must be controlled at the ECU.
