hey i got a 91 dx hatch obd0 B16a and a PR3 ecu . Do i need to run the knock sensor with a PR3 ?just cause the plastic part of the plug on the knock sensor broke off ,and i heard of some ecu's r able to bypass it. Or should i replace the knock sensor and run the wire? I tryed searching for it but couldnt get a 100% sure answer...can anyone help me?..Thanks.
