What's with all the knock?

[iBoostDSM]

My car is driving me crazy!!

I just put in a new front o2 sensor which helped out a lot but my car is still crazy.

As you can see in the log I have multiple accounts of 12 deg of knock. What is causing all of this. My mods list is up to date. I need help!!

In the log it's an excessively log warm up idle followed by a little cruise, it was all wet out and raining so no wot. Then finally another excessively long idle.

I'm pretty new to ECMlink so don't know a whole bunch.

Any help is welcomed. Thanks

First, Do a Boost Leak Test, To make sure that you are good on that side.
What plugs are you using?
You should be using NGK 16's or 17's.
It might be phantom knock, But, First you have to check everything else is working good.


I can see in your profile that you have a wide band.
Make sure to Campture your Wide band and
TPS.

I have done multiple boost leak test recently and the only one left I can hear is on the driver side of the fuel rail somewhere. I was only able to build up to 15 psi, then I found out I should rotate the engine 30* ATDC, I will do that next time.

As for plugs I have NGK BRP6ES, that's what it says on punishment racing, not sure if they're 16's or 17's.

Sorry about not logging TPS. All the setting got reset because I disconnected the battery. And I'm not sure how to connect the wideband, I will look into it though.

First and foremost you need to be logging more items. As for the knock it seems like something is causing the knock sensor to pick up vibration of some sort. Go over everything to make sure you have nothing banging around while driving. How old is the sensor? I would also go to the dash tab and lower the knock read to 3. Then go to the knock tab and set it for 3000rpm and 30 tps.

bpr6es are 6's and
bpr7es are 7's.

Make sure to do the leak test at 15psi.
and make sure your spark plug wires are good.
Keep on mind that you need to have no boost leak at all before going to the next step.

Yeap. If that's a phantom knock, that should solve the problem.

I'm not sure on how old the sensor is, I'll try and pick up a new one.

And I do hear stuff banging around sometimes. Usually during low rpm acceleration. If I'm in 4th gear and around 2750 rpms it's really sluggish and I hear some clanking.

My wires are pretty new so they're good, should I get different plugs ot are those fine?

I've been trying very hard to fix my boost leaks, and I'll change the settings in the dash tomorrow morning and see what happens.

Thanks for the help
