Sequential injection

[JohnP]

What exactly happens on a system when the secondary trigger is not used. I have yet to connect my secondary trigger on a wasted spark v8 setup. The injectors are all wired individually unlike batch fire. The vems is the newest model and the injector angle curve is currently set at default 720 on all. Am I risking anything running like this? Will the secondary connection with cam sinc on make a big difference. 

Thank You,

You will not risk anything.

The difference will be based on the inlet system you have, large ITB´s wild cams and so on at low engine speeds most of the time.

 So is it worth even connecting the secondary trigger then? The vems was ordered for hall secondary and as it turned out the secondary trigger is actually vr.

If I could effectively run that car without it, what would I set the injector angle curve setting to? no cam sinc?

[JohnP]

 Its wasted spark and the injectors are set to fire in sequential order. But without a secondary trigger what can go wrong if anything?

Worst case is that the injection is 360 degrees off from "camsync", which would not be noticeable under nearly all circumstances.
