Sync loss while cranking.

Sync loss while cranking.
Hi,
I am having some issues where the engine stops turning while cranking.
I can see from the attached log that I am getting an sync error 31 quickly followed by a error 32 while cranking. Rpm jumps to around 2500 while cranking and ignition spikes to around 30. Seems like this is causing a backfire and it stops the engine from cranking.
I have attached a log from the startup, as well as the tune. I going getting a composite log tomorrow morning when the car has cooled down as I am not having issues on hot starts..
Battery voltage is dropping a lot just before the errors. Could this be due to a faulty starter? The battery is brand new!
BR,

Tried making some composite logs, seems like it stops logging sometimes while cranking. Anyway, I have made some progress. If I turn the key to the "on" position and let it sit for about 30-45 seconds before cranking, the chance of kickback is much lower.. Replacing the head this weekend, so I am going to clean the connectors at the same time, as well as checking grounds.
