I just ran a datalogg on my 2011 for shits and grins. I am running Stock right now till the heat subsides some. Temp outside this morning was right at 80 degrees.
Came up with some interesting readings. This was a WOT 1-3 pull.
min/ max/ average
AFR Bank1= .776/ 1.999/ 1.193
AFR Bank2= .831/ 1.999./ 1.177
ETC Actual Angle= 1.227/ 81.000/ 20.175
Knock Sensor= -3.227/ 0.000/ -.0124
Lambse b1= .830/ 1.023/ .931
Lambse b2= .830/ 1.023/ .929
Load as Fraction= .090/ .986/ .286
spark advance= -3.500/ 48.000/ 35.286
I am running 92 octane fuel that i get from my local BP station here in town. To me it looks like the stock ECM settings are running really rich and is picking up knock and retarding the timing. I am not really familiar with the Knock sensor numbers or the spark advance numbers, so if someone that knows for sure what it is doing please chime in. Spark advance seems really high for stock settings????
I did this to basically learn how to datalogging and to see what I need to keep an eye out for when I reload my tune. Again ANY help would be appreciated.
Was your knock at tipin?
So it was tipin. Did your logs show a decrease in load and an increase in timing during the shift? If so I am not sure you will ever be able to completely eliminate knock in that situation.
Quick question: Is spark advance essentially the timing?
