Default New Day, new issue E39a pcm not charging

You guys bale me out a lot. Hopefully someone has seen this. 2015 3.6 LFX with auto into an RX8. Up and running and trans is talking to pcm. All good there. No charging output from alternator. Have tried both options in HP tuners. Under system>general>alternator> voltage control, I have tried "fitted" and not fitted. I haven't tried any of the other settings.Thoughts, ideas, suggestions? Thank you.

We usually connect ignition voltage to pin #1 on alt and call it a day. Works fine. Steve

We just had a E92 swap that would not charge all the time. We ended up having to change some of the factory alternator setting with HPT and its been charging for 2 months now.
