I picked up some engine Knock in 2nd gear @ around 6600 rpm

http://www.bootmod3.net/log?id=5ecc566fae729b7fe2fb9316

Just wanted some thoughts on why and whether I should worry about the knock

This is stage 2 e30 and I'm running a fuel mix of 93 and ethanol @ about e40 gas

Sooo I don't think bad fuel

It just happened once in this log

Then goes away throughout rest of pull

I was running other tunes all day logging without any indication of knock this was first time today

And my timing is great so I don't think gas ?

Thoughts

Ignore ? More serious ?

Did you speak with your tuner?

Not yet. It just happened

...I messaged them

Just curious what others think

I wonder if rain and slippage @ wot can create weird air / fuel mixture and short term detonation...

That's a high probability. I wouldn't stress too much about it. Just see what tuner responds with...how many knocks did it pick up btw?

Just 1 around 6600 rpm in 2nd. If you click the link above you should be able to see knock detection right around there
