[QUOTE="fabianyee, post: 109186, member: 6"] Engine running with OBDII ie the E36 328i and the E46 would not benefit much from piggyback ECU. Only the early engines running OBDI would be able to get more power from piggyback ECU. the ECU would detect the change and revert back to original mapping especially when it's receiving the signals from the lambda sensor (oxygen sensor). So reprogramming the ECU is better for engines with OBDII.. [/QUOTE]
