Cooper Posted December 30, 2019 Report Share Posted December 30, 2019 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?

Brad Burnett Posted December 30, 2019 Report Share Posted December 30, 2019 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.
