N/A knock sensor output
4 Attachment(s)
My knock sensor is going nuts at low load and low RPM, but the knock retard isn't being triggered. Is it actually knocking, or is this just signal noise? I've looked for other people's knock logs, and it seems like they're usually nice and flat until there's knock event, and then it spikes. Is there a way of filtering the output?

Also, I haven't changed the spark timing from what the MS came with from Rev, so I'm not doing anything crazy or aggressive. You can see from the graph that it's not lean; and the temperature outside was like 65*F, so if it is knocking, I have no idea why or how to get rid of it.

Anyway, any advice would be greatly appreciated.
