This is a small section of some logs i did last night. I was just cruising around not really purposefully doing logs, just enjoying a nice evening when my wife called and hit a deer. So then i went out to see her and the damage. So i cant say what gear i was in, hills or flat road or any other variables. The car has a tune, 3 inch TBE w/HFC, MBC set to 23 lbs, cone filter on a maf adapter and a walbro. Every once in a while i will get a few counts of 1's and 2's here and there. But in this log im showing 5. My first reaction is to take out a degree of timing, but ive gone about a month and a half without altering this tune (from a vendor) and its been perfect up until last night. Maybe just ride it out and keep an eye on it?

 

Anyone have any input?

 

what is knock like on the WOT runs?

anywork been done under the hood lately? ....possible rattle?

(I would say not to worry too much at those amounts....but if it carries on try pulling some timing)

 

ugh y cant i open the attachment?

 

My WOT runs look good. I either get no knock or a couple counts of 1. Nothing on the car has been modified since i got my tune. I sured up all of my tie bars and checked exhaust bolts and i have no issues with either. Thanks.

 

1 count of knock is negligible.

 

There is a 5 count that drops down as RPMs increase starting around 2900 or 3000 rpm. You have a load of like 235 at 3000 with 4 degrees of timing. i would just pull 1* of timing right before the 5 count and see what that does. The knock is at partial throttle which is really hard to tune for and is time consuming.
