BB and modern 8 speed Auto transmission ?

Old Thread I know. Has anyone gotten this up and running? I was going to adapt a A518 behind my 383 in my B Body but given a good used 8HP70 cost about what parts are going to cost to build the 4spd and they both have to have the same adapter it looks promising.
The controller the guy built was just an Arduino, nothing too complicated. His program was simple and he shifted it via button.
