    I have a 90 Si with a D16Z6 in it. The ecu is a P28 and I am using a jumper harness.
    My problem is that it is hesitating at mid throttle and I cant check the codes.
    the old ecu had a light right on the ecu but the new one does not. does anyone know which pins on the ecu need to be jumped to check these.
