  1. Can you do this with GM’s CAN bus? I’m working on an LS3 engine swap, and this would be awesome!

    1. Hi Greg, thanks! We’re checking if the LS3 is simply CAN OBD-II, which would be super easy; or if it’s a proprietary GM protocol, like the BMW E46 is. Know more details, specifically if there’s an internal CAN protocol?

      1. Sorry Brent, didn’t your reply. I’m trying to look into how the GM protocol is done. I’m new to the software side of things. Can I email you more about this?

  2. How did you safely tap into the CANbus lines?

    1. It’s easy to do with posi-taps – they’re likely the highest quality wire tap in the industry. check out the instructions here:
