Robert, >From what I can tell from your pics, it looks like there are no traces going to these pads of the pin (no connections to any other component). It looks like someone had already replaced this chip before and the missing pads are a good sign that they heated them to much with the soldering iron and the copper pads came off the fiberglass board, that is why they left them "naked". Also it looks like the two pads overlapped each other (from the looks of the white circles) which indicates that these two pins are/were tied together, I can't be sure without a schematic of the unit but if they are suppose to be connected together then it is very easy to fix by soldering a small wire between the two pins. If they don't require to be connected together then you can leave the pins as is since they don't need a connection. The green stain on the componenet side of the board tells me that some moisture had gotten onto the board at some point and corroded the component, probably why it was replaced. Before you tie the two pins together see if someone else you know with an ECU can open theirs up and look at the pins or see if someone has a schematic. I will try to remove mine from my car (I am currently restoring it so it's in a thousand pieces right now so what's one more part :) ) and open it up and look at it.
