MSI 2.2 runing spark

Ok so I've got an MSI 2.2 (green pcb) and I want to run spark now. So from what I've gathered with the MS1 board I need the Zeal board, wired like the pic below, and the pull up resistors installed at the LEDs. Then obviously changes in Map for ignition. Just making sure thx guys

Basically. You can use the Zeal card, or make a dual LM1815 circuit on another board. The Zeal is easiest and also comes with a few other features.

Like other boards, the 2.2 needs pullup resistors on the LEDs.

As always thanks a ton Aaron, I just want to clarify before I jump into this. The pullup resistors on the LEDs need a 5v supply right?

Just follow the instructions in the FAQ for adding the resitors. These are valid for both 2.2 and 3.0.

Thx Aaron. I apologize for overlooking that and I kinda feel like a buffoon!
