I would know if it's possible to send each 90 pulses a msg.payload. So the other 89 pulses no msg.payload to the next node

A message is sent from a function ONLY when `return msg` is reached OR `node.send(msg)` is called.

Therefore, if you move `return msg` to inside your `if( I >= 90 ) { ... }` block, that will make sending messages conditional.
