Coil dwell figures

[Chris Wilson]

I refer to Motec drawing M26 for Nissan 6 cylinder coil on plug amplifier wiring. I am running a Skyline RB26 engine as coil on plug but with sequential spark, not wasted as shown on the drawing. In the "Setup" box on the drawing it shows a "dELL" figure of 1.5 Now I assume this is NOT in milliseconds? What is the figure representing and is it still applicable to using this amplifier as a true sequential fire ignition set up on an M800? Thanks.

The dELL value is in milliseconds. In the M4 and M48 ECUs a positive value sets the dwell at 15V this is then adjusted automatically with battery voltage. And yes this is still applicable to using the amplifier for sequential ignition as each coil is being charged individually.
