[SNOWBIRD]

so your telling me that both 35 are telling me that the top 02 and 9 knock happened at the same time and mph thanks

 

[WS6]

Yes... and to quote Turbobob;

"left side is the mph of the lowest O2 reading

right side is the mph of the highest knock retard reading"

so both happened at 35MPH...it was leanest and knocked at the same time.

Not the end of the world. Be carfull and watch that scan tool. Sometimes Violent burnouts can tickle a Knock sensor.

I dont think 9 degrees of knock is a thickle.

Don't sweat it too much. At 35 MPH your not loading the engine very much, even if it is real KR. My guess is that it is false KR from spinning tires. This is very normal. Look into getting a false KR ignore in your TT chip. It will ignore KR for the first few seconds. If not, you'll go crazy chaseing your tail.

Happy spooling.
