    A good adapter boardBought this to adapt my DIYPNP to a newer engine loom. A good fit into the case.

    It doesn't have silk screen on the bottom of the board like other adapters, which can make things slightly difficult as you have to flip the board and note a pin location if routing wires through the bottom of the board.

What engine management systems can I use this with?

  • This breakout board is not specific to any particular engine management. You can use it with any ECU that is capable of running your engine and has the features you need.

How exactly do I connect my ECU to this one?

  • Start with a harness that has the ECU on one end and the other end unfinished. Run it in through the grommets on the back of the case, and then solder it to the main board.
