I know the p05 runs off a 1 wire o2 sensor but besides that? Can that be turned into a p28 such as the p06 can be? Do they have the same maps or they different? Now if I chip a p05 can I just plug it in or do I need to mod the o2 sensor wiring? I got a couple of these ecu's from swaps I picked up and wondering what good or useful these ecu's are? Thanks
