Cam level trigger edge

Recommended Posts

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.

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.

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.

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.

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.

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?

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.
