Be careful if using the factory knock sensors. They are high impedance and you may load up the circuit if you put the Knocklite in parallel. According to the 2009 FSM (EC-530, see also footnote 1), you should have 2.5V at the sensor terminals at idle. If you have much less than that, the ECM may not be able to adapt. Measure before and after installing the Knocklite.
