My specific question is regarding Lightpulsar Dragon and why it misses it's timing (such as when synchro summoning), while cards like Tuningware don't. I am mainly just looking for an explanation as to how and why cards miss timing, as I have been playing Yugioh for years, but have never quite understood why timing is such a frustrating rule to understand.

Pulsar says when, tuningware says if.
When Pulsar is sent to the grave during synchro summoning is in the middle of a resolving chain, and nothing can occur other than the resolving chain.
However tuningware and similar cards that say if only require it to go to the grave sometime during a chain to have their effect go off
