MILCman Posted April 17 Report Share Posted April 17 Hey guys, and thanks in advance for your help; I have searched for this and can't seem to find a definitive answer, if I'm missing it somewhere please feel free to point me in that direction. I am soon (ECU is on backorder) going to be running and s13 Nissan SR20 with a G4X MonsoonX. For those not familiar, the SR20 originally uses an optical Cam Angle Sensor for all of its triggering, with 360 degree slots and 4 slots for sync. This setup tends to cause sync issues in higher RPM (especially at limiter) so it is relatively common to change the trigger disc out for a missing tooth wheel; in my case I have ended up with (came with the engine) a 24-2 wheel distributed by DIYautotune. This disc only has one set of slots, so I believe the proper setup would be to use these slots for Trigger1 in a Multi/Missing Tooth config, with Trigger2 sync set to OFF. Now my question is: If I run off of only a 24-2 cam trigger do I lose the ability to run sequential fueling/spark? I'd rather not limit myself to batch fire/wasted spark. If needed I can buy another disc with 2 sets of slots but I don't like that option as, from my understanding, it's no more accurate if both triggers reference the same wheel, and the cam signal should provide enough info for sequential.

Laminar Posted April 17 Report Share Posted April 17 Set Trigger 1 Multi-Tooth Position to Cam and Trigger 2 Sync to None and it should be capable of sequential as the ECU knows the full 720 degree cycle. Quote Link to comment Share on other sites More sharing options...
