What ECU ?

What engine exactly?

Regardless, Install a reliable crank signal to begin with. Synchronizing means: To align the camshaft position to the crankshaft position.

I have not yet heard of a camshaft signal to be synchroninized to its own source. Even If I may lack information in this particular case, it is generally best practice to trigger crankshaft-position directly off the crankshaft.
