I don't know of any retrofit kits, but I did hear that the sensor has to be tuned to each motor to be able to discern knock from other engine noises while running. Not sure how easy that would be without some other method of differentiating the noises.

I would be interested in one too. Perhaps, AndyF or Rich from Fast EFI will chime in?
