He's using a toothed wheel on the OPD to create a signal that that locates TDC #1 , or similar, to let the EMS know exactly where in the cycle the engine is. It's not just one magnet, but multiple teeth so the resolution is better. The ability to use this type of signal varies by EMS. To the best of my knowledge, XFI can't use this type of signal. A few that can are Pantera, Simple Digital Systems, Haltech, Megasquirt and Motec- there's probably more I can't think of.
