Gas Pedal Delay

DIGItonium

I just wanted to touch up on this topic in regards to updates about my recent experiences for the past couple of months. As usual, my drives are to and from work in a span of about 15-20 minutes of driving. I also ran errands as well, so that adds about an additional 15-30 min of driving.

We had a couple of unusually warm weather over a week ago with near 70s. I can get the oil temps to hit 200. Then I've also driven the car then the temps were in the 20s and 40s.

The car has not been acting up lately. Throttle and electronic pedal feels is very good with hardly any dead zone or hesitation. The car immediately responds under 3k RPM when I give it more throttle. I get my 91 octane fuel from the same stations: Conoco and Philips. I don't see a 10% ethanol sign at these stations compared to Quick Trip. I'm not sure if that or winter mix makes a difference either.

What's this "tip in" knock that some owners has been experiencing? Is a case where the ECU quickly retards timing on throttle tip in? I was reading the Stillen SC thread, and owners talk about increased "tip in" knock as the engine gets hotter from longer duration of driving.

If so, what's the most economical way to get a visual or log engine knock or events where the ECU retards timing due to various factors including knock?
