This is all I have for AU II, no VCT manual sorry.  I make a note of them as I find out, either from questions or from ECU’s I see on eBay.
 
12Ax and 12Bx are the norm for standard engine, but when you go to tickford there are heaps.
 
If I really needed a VCT manual then I would download the Auto one, check out the VE table, then download Manual bins and compare them. Or ask on the forums. I'm guessing they made one with a manual ?
