Don't waste the EGR-T input on a resistor, you can use that to log a map or a wideband or something useful. The california/fed configuration is selected by resistors on the board, you just have to clip the right one and it goes into federal mode. I can't remember which ones, you should be able to find the info in a search. If not, try searching the dsm-ecu yahoo group, I know the info has been posted there.
