    E40 Knock Sensor Question

    I notice on all E40 PCM tunes I pull up, all their Initial Level for Knock Sensor's is 400. All PCMs after that are 120. This is the correct value right? I assume the location of the knock sensor must change in the later years.

    I swapped a cammed ls7 into an 07C6 ls2 and had serious issues until I entered ls7 knock sensor data-it didn't show knock with the ls2 settings. Seems like when there are issues with modded motors, the solution is to over octane and play with sensitivity settings until kr goes away. If there is a proper method, I would like to hear it.
