Paora Smith Posted September 6, 2014 Report Share Posted September 6, 2014 Hi guys  Im just about to upgrade my stock 2jzgte vvti coils to ls2 coils. The setup I have now the ecu sends a negative signal to the igniter. But with the ls2 coils they need a variable 5v+ signal to fire(So I have read). Has anyone run these coils before? Is there any truth to this or do they run a negative signal also? If they do run a positive signal how do I get around this? Thanks Quote Link to comment Share on other sites More sharing options...

Simon Posted September 8, 2014 Report Share Posted September 8, 2014 All you will need to do is remove the igniter and wire direct to the ECU. The ECU ignition drives will drive positive for the dwell time and then the coil will fire when this is switch to ground. Quote Link to comment Share on other sites More sharing options...
