I've decided this is a lie.
On the crank the the signal it strong and clean which is what I was focused on, but there is a mis-match betwen the sensor core and the tooth width resulting in a flatat the zero crossing point...which means there will be jitter or random error in the tooth position readings. I should have noticed that before and its probably why the ECU is struggling to read it. I think I need to replace the sensor....
Looking at the cam signal, its weak which I knew but there is also odd noise in it.....I suspect that at cranking speed the cam itself is not moving very smoothly and combined with the weakness its just hard to read. I think I need to replace the senor with one that is not sensative to this
VR sensors out, hall sensors (which I don't normally like too much) in. I have one that should work nicely for the cranks, I just need to make and adapter.
For the cam I ordered this:

Cute little thing, same brand/family as the one I have for the crank but only 1" long so it shouldn't be ugly on the cam cover. Its a weird thread though 15/32-32, the tap may not make it for the weekend.
These changes should resolve all my timing issues....should......
