Hey guys,

I am looking to find what you are all using to listen to knock on the engines you tune. I have made a knock listening device for the Nissan cars I have tuned and it works well but I am looking for other ideas on the least intrusive way to monitor these engines for knock. I want to be able to listen along side of what the knock sensors are saying to rule out any false knock (or vice versa). I would prefer not to have to hack any harness's or cause any irreplaceable damage to the vehicles being tuned.

I am currently tuning a LS1B controller however I would like to have a solution for all the EFILive supported controllers.

If anyone cares to see the device I made here is a link to the instructions to build it, while it would work I would imagine on these domestic vehicles I have to splice into the harness (or use a patch harness) to listen in.

Thanks in advance.
