1uzfe non vvti Dwell settings

[Cooper]

I am running a 1uzfe non VVTI using the factory distributors and igniters.

I am using a modified 1uz VVTI base map configured to run the twin spark

From what I understand the dwell is controlled in the igniters

Am I best to just set the to something the same across the board or will it make little difference?

Dwell is controlled by ecu as the toyota ignitor is just a standard dumb ignitor. 

Very similar to the celica ST185 coil and ignitor.

I would copy settings from the base cal for the st185 which has a dwell of about 4ms.
