The idea for this comes from Jon over at Chippernut.com The wiring is basically the same and the fuctionality is simalar to the V1 (http://www.chippernut.com/blog/welcome) but the code has been reimagined from the groud up and uses the CAN Bus libraries from sparkfun to send OBD PID requests over the CAN bus using the MCP2515 chip
Blog post for this too: http://crumpspot.blogspot.com/2015/09/can-bus-sequential-shift-light.html
I also ended up making a custom board for this too.
