Bugatti chiron missing buildbox

[Lebigfrog]

Hi, I've been given a bugatti chiron technic set 42083, this was found in a closet of an empty property, so my mate knowing I love lego gave it to me thinking it was complete. Unfortunately it looks like who ever had this set, completed buildbox no.1, took it with them when they moved out and forgot the rest! Is it possible to get a breakdown of the parts contained in each buildbox? Can anyone recommend any building apps/sites for lego technic?

I am not sure I can help a great deal, but have you looked it up on Rebrickable? There are some pretty good details to find on the site. 

Otherwise, I am moving this over to technic to see if anyone there might know more

Didn't check the instructions myself. But that the first place I would check. Maybe it refers to boxes.
