It's because it's an 01 ecu with an immobilizer. You'll have to bootmode flash an M-box file onto the ecu, or defeat the immobilizer. After that you can flash normally. Just trim the tab in the ecu with a razor blade, or if you look at your wiring harness plug you'll notice it will take 2 seconds to make it fit.
