Need to set the VVT switch over map aswell, otherwise ECU will see cams as reading wrong.
I tried that at one point but it caused all sorts of weird issues, I remember the biggest one was fuel trims not setting and a general lack of power (didn't do any logging to see exactly what was causing it though). I don't think the ECU liked the fact that it was never able to monitor the VVT tensioner operation since diagnosis could only happen if the changeover happens. I don't see how the ECU would see the cams in the wrong position since that's the job of the CMP, otherwise you wouldn't get a cam position code in the first place.
@fukenbroken: I have an ATW motor with an AWM ECU, so I never had VVT in the first place. I recently also copied KFZWOP over KFZWOP2 and it seemed to have helped make everything run a bit smoother, but that could be my imagination.
