Hello @Adamw

With the trig 2 arming thresholds set very high I suspect you are sometimes mis-syncing during startup, since you have wasted spark ignition the engine will still start so you wont know - but the cam position will be 360deg out from where the ecu expects it to be.   

For reliable sync your trig 2 arming threshold should be something like this:

After changing that, do a store and power cycle ignition/restart, then use the cam angle test to determine the correct offset for the trig 2 VVT offset.  You are currently set to 650deg, it is usually around 170.

What did your trigger 2 offset end up at after recalibrating?

You are using the wrong trigger mode and the trigger 2 sync mode is set to none as well.  

Change your trigger setup to look like this:
