warmup Posted November 17, 2015 Report Share Posted November 17, 2015 ECU: G4+ Fury.Engine: Honda B18C with 24 tooth distributor.Triggers setting: Cam 24 tooth / Cam 1 pulse.Engine started good and had a very stable idle, but no rpm reading.Trigger scope seems good too.But do you believe the engine is actually running when you see the readings?Any suggestion?

warmup Posted November 17, 2015 Author Report Share Posted November 17, 2015 (edited) OK, I didn't read the wave form carefully.I realized that the trigger 2 actually was triggered 4 times per 360 cam deg.I guess the trigger 2 was wired into the 4 tooth sensor not the 1 tooth sensor....but engine couldn't start after I wired the trigger 2 into the other sensor.

Simon Posted November 17, 2015 Report Share Posted November 17, 2015 Trigger two polarity is incorrect. Signal and ground connection need to be swapped.What are you triggers settings set as?I have seen a 0RPM reading when the trigger 2 mode is set to cam level. This would be incorrect for this application.Triggers should be set as below. Scott 1 Quote Link to comment Share on other sites More sharing options...
