I'll admit I don't know much about Megasquirt. It was installed by the previous owner and I'm still learning it. I've got the basics of tuning down. The problem is that I hear a clicking noise like a bad relay from the board. Its only when the car is running. I can turn the keys and just hear the fuel pump normally. Does this happen often, do I just need to replace the relay? Who carries something like that, Radioshack?
