cam input in vvt

[AbatelliCristian]

Hi, I have question.
In vvt I have 2 (or 4 sensors). is it possible insert the choice between vvt1 and vvt2 for cam input? this choice is used to test which configuration is best for the sync in the crancking.
In s54 I have used vvt1, intake. But I realized that my choice is wrong, because intake have 6 tooth and I have always sync in pms, both in the exhaust phase and the compression phase.
In vvt2 I have 8 tooth and I think is the correct choice. Now I invert the wire, no problem, but if in the future it is possible select vvt1 or vvt2 via software, this can facilitate the choices.

It isn't an easy change to make.
The composite log you posted (VVT1) looked just fine for "poll level" - what problems are you seeing?

I attach the composite.
You can see in any case, I have sensor cam in any case at 11-12 cranck tooth (phase compression or phase exhaust)... same time the engine not start in sequential. In semisequential start very well, but in sequential no.
