Installed new parts, knock

[AshFromCan]

So I put in some autotech internals and a Cobb TIP yesterday and did a fourth gear log today. I'm seeing a bit of sustained knock about halfway through the pull. I'm not sure what it means.

My mods are : Cobb TIP+SF Intake, Autotech internals, Cobb XLE BPV, Cobb OTS map on 91 Octane.

Appreciate any help.

cant help you without logs

[AshFromCan]

Oh my bad. I forgot to upload them.

Check to see if you have any leaks...I am not expert but your AFRs look a little wonky...that being said the pump is holding pressure just fine...Also not sure about Manitoba gas that could also be the issue. Were you getting knock before the install?

[AshFromCan]

No I never noticed any leaks on previous logs.

[nilashish]

Yeah the AFRs could just be the OTS map. Ill let someone more experienced chime in...

Does it do it all the time? If you can't replicate it, it might just be noise.

Did you have TCS and SWAS turned off(Genpu)?

I narrowed down some random KR like that in logs and found out it was cause I didn't turn it off(during Tuning I turned it off, but forgot when I decided to do some newer logs).

I thought it was due to bad gas, but subsequent logs I remembered to turn it off an it didn't happen again.

This guy.

If you can repeat it, try new gas as well. Some places just have shitty batches.

I have seen gas fluctuate and cause this from tank to tank. I try and stick with the same or known good stations. Also i'm not certain because i don't have all my logs in front of me but your boost air intake temp looks like it climbs a bit fast and correlates to this knock. could be something to do with it as well.

I always get gas from the same place. I don't know how "good" it is but it's what I always use. I'll check all my tubes and lines, change gas stations and do some more logs and see what happens. I'll try 94 Octane with a difference map too, see what that does.

Thanks for the input.

I checked my work over and found the clamp holding the TIP to the turbo housing was super loose and the hose was almost coming off. Sorted that out and took some more logs. Looks like that cleared up everything. Thanks again for the help. I'll attach the logs if anyone's interested.

Looks good.

Time to free up the exhaust!

i know this is an odd question, what is your tire pressure at?

in good spirit.

Around 35 PSI I'm guessing. Dealer was storing my wheels for me and put them on. I haven't checked the pressure. Stock wheels are tires. Why do you ask?
