Ok this is startiing to drive me nuts! I bought my CRX with a 96 GSR motor, now what I cant figure out is how they can run OBD0 on the car and have no codes? I thought the 96+ cars have OBD2. Now if I want to use a OBD1 ECU on the car, does that mean I only have to get the jumper? Can someone helpme out please. I dont understand this OBD crap. Are there sensors on the block for the ECU? I just want my car to run right.
