Adamw Posted June 22, 2020 Report Share Posted June 22, 2020 The LS3 doesnot have VVT. I believe only a L99 does. But the L99 also has the weird "active fuel management" where they basically turn off 4 cylinders under cruise conditions. We cant control that system. As far as I know we have no info on the L99 VVT. It is unknown whether we can control it or not. If you do a triggerscope I can at least tell you whether we have a trigger pattern that will support a moving cam. Quote Link to comment Share on other sites More sharing options...

Adamw Posted June 22, 2020 Report Share Posted June 22, 2020 These are the engines that have vvt, LS3 is not one of them. As I said the L99 would be the closest to a ls3 with vvt.

George GEP Posted June 26, 2020 Author Report Share Posted June 26, 2020 here is Map and triggerscope link together https://we.tl/t-HF3ozH2bZB please check Quote Link to comment Share on other sites More sharing options...
Adamw Posted June 26, 2020 Report Share Posted June 26, 2020 Your cam sensor is not working in the triggerscope, it looks like it is possibly wired wrong as it is sitting at 1.5V which is not normal. Quote Link to comment Share on other sites More sharing options...
Stevieturbo Posted June 28, 2020 Report Share Posted June 28, 2020 fit a normal camshaft and dump the vvt. Quote Link to comment Share on other sites More sharing options...

Adamw Posted July 10, 2020 Report Share Posted July 10, 2020 Try the LS2/7 (90 offset) mode. Trigger offset will likely be close to zero. Quote Link to comment Share on other sites More sharing options...
George GEP Posted July 10, 2020 Author Report Share Posted July 10, 2020 trigger 1 and trigger 2 both Rising? or falling? or ? Quote Link to comment Share on other sites More sharing options...
Adamw Posted July 10, 2020 Report Share Posted July 10, 2020 That will all be set automatically when you choose LS2/LS7. I would expect falling on both. Vaughan 1 Quote Link to comment Share on other sites More sharing options...
