JayGow Posted August 10, 2017 Report Share Posted August 10, 2017 Can't seem to find a clear answer for this in the help section. Can someone please clear this up for me.If cam level signal is low when missing tooth passes crank sensor (no1 ign stroke), and then goes high at 90deg ATDC, should trigger 2 edge be set to rising? or falling?Running wasted spark, sequential injection. G4+Fury.Cheers. Quote Link to comment Share on other sites More sharing options...
Brad Burnett Posted August 10, 2017 Report Share Posted August 10, 2017 This is really going to depend on where TDC is in relation to the missing teeth. Please post a trigger scope trace. The ecu does have an onboard trigger scope. Quote Link to comment Share on other sites More sharing options...
Simon Posted August 10, 2017 Report Share Posted August 10, 2017 HI Jay It wont matter as if you are running cam level it purely looks to see if signal is high or low, the Edge is not used in this case.But the signal must be High as the gap passes for the next turn of the crank.

JayGow Posted August 10, 2017 Author Report Share Posted August 10, 2017 Ok so starting from tdc, at the moment cam level is low at missing tooth then goes high mid power stroke.Level is high at missing tooth and goes low mid intake stroke.I think that's correct but just not 100 percent sure. Not getting any trigger errors, just want to make sure injection timing is correct. Quote Link to comment Share on other sites More sharing options...
Simon Posted August 10, 2017 Report Share Posted August 10, 2017 That is correct.Are you running wasted spark or distributor? Quote Link to comment Share on other sites More sharing options...
JayGow Posted August 10, 2017 Author Report Share Posted August 10, 2017 Running wasted spark. The car runs fine.I retarded cam timing a couple of degrees and it has upset lambda readings quite a bit more than I was expecting. Just wanted to confirm my trigger sync was correct before I adjust the tune. Quote Link to comment Share on other sites More sharing options...
Simon Posted August 10, 2017 Report Share Posted August 10, 2017 A test to confirm your injector timing will be to set the ignition mode to direct spark and see if timing is correct on cylinder 1 while cranking then turn back to wasted.

JayGow Posted August 10, 2017 Author Report Share Posted August 10, 2017 I'm running duel post coils with a 3 channel igniter on a 6cyl EF falcon. Spare ign channels are being used as aux outputs.Is it safe to switch to direct fire for this test? Quote Link to comment Share on other sites More sharing options...
Simon Posted August 10, 2017 Report Share Posted August 10, 2017 You would need to disconnect the spare ignition channels as they will try to fire when you do the test. They will need to be reset to the Aux functions once done too. Quote Link to comment Share on other sites More sharing options...
JayGow Posted August 11, 2017 Author Report Share Posted August 11, 2017 Ok no worries. Thanks Simon Quote Link to comment Share on other sites More sharing options...
