Default AEM Tuning

I made a log the other day having my brother drive me home from work. I logged timing, RPM, and knock voltage. I had a couple of spikes, and I am pretty sure those are the knocks I am seeing. Do I pull a few degrees of timing, add fuel, or both? If you want logs of something else let me know. I'll post it up later, as I am in the hospital today.

you can email me your map and logs, i'll see if i see anything out of the ordinary.

do you have a wideband in the car?

in addition to what you have, logging o2, throttle and engine load would be very helpful

^what he said. Just to let you know, if you encounter knock, you should NEVER add fuel. Doing so might actually make it worse. Just retard timing.
