Everyone post logs please

I need some evo (8 prefferably) logs with idle in them. I want to see what my knock sensor is seeing compared to others at idle. Please include whether you have aftermarket cams/internals etc that might make more engine noise. I want to see if it is reasonable to just slightly offset my knock voltage to be more like a stock car so I don't get erroneous counts due to my increased lifter noise. Thanks in advance.

The ECU+ zero's out the knock voltage at idle, so logs no gonna help.

Why that? Technical reason?

Seemed kinda worthless to show knock at idle, since there really can't be any. That was my train of thought anyway.

...mine shows a knock voltage. I'd like to see some logs with and without cams to see the knock voltage difference where I know there's no knock....Idle. I will need a great many logs to make a concrete decision on how I'd like to scale mine (if at all).

Hmmm. My logs show no knock voltage at idle, which is how the software is supposed to work. I'd like to see your log that shows knock at idle. Does the ECU+ load display in the engine monitor show "Idle"?

here it is. Yes it shows "idle". Could this have anything to do with the fact that you can't get my P0300 to go away?

Correction: I look for throttle-closed to turn off the knock reading rather than idle. (It's coming back to me... don't show knock at idle or when shifting.) Looks like your TPS sensor is kinda-high when the throttle is closed, and of course it exceeds my throttle-is-closed threshold. Thus, the ECU+ always shows knock on your car.

yeah I've noticed that. I'm gonna look into it a bit when I get the car back in my hands. Couldn't have anything to do with the GM 3-bar being attached to the 5V source from the TPS could it? (Last I checked my 3-bar stopped working too. I switched it out for another and it still didnt work. Havent had time to work on that much. It always reads "0" psi)

I guess it could be related to a bad sensor on the +5v line. Check that supply with a digital meter - it should be right on at +5v.
