i'm not really sure. but i THINK "right away" is used mostly if the action or the event is still to be done or still hasn't been done whereas "right now" can be used in the present progressive (the action done is still going on or still applies at the present) and can be used also for future actions, esp. in giving an order or requests.... love the question! it made me think a while....hope this helps!

right away, when you say it, it refers more on you're act. and when you say right now it refers more on time.actually it has the same but in some ways they are quite differ for one another.

The same meaning. just in different phrases / words
