That makes complete sense. You would have to use the GA16DE sensors since its a GA16DE ecu that you are trying to reprogram. I would get an SR20DE ECU if money was not an issue and have that reprogrammed. Also, the years they are talking about relate to the GA16DE ecu and not the SR20DE ecu. They can reprogram ecu's from 91-97 for the SR20DE.
