Default False Knock?

Here's a screenshot. I can make it bigger if you can't see it.

8.5 psi. 29* up top.

I have swapped to the 6.0 heads too, so the CR is around 8.5.

The 15psi you see on the log is actually the OEM map sensor picking up 105kpa.

Yeah I don't know to much about tuning yet. I hope to get hptuners soon. Is this about the same set up you had when you pulled off the 12.6 run?

Yup ... except it was shifting whre it was suppose to (6600) instead of tagging the rev limiter at 6900 rpm.

With sticky tires ... this would be on it's way to a solid 12 second run.

I take that back ... It's about 6* more timing up top from what's in the video link in my sig, if that's what you were referring to.

Is that KR happening during the shift? Looks like it. Its interesting that it goes away so quickly.

i get false knock whenever i downshift and get into it. 4 degrees. from 4800 to 6400. it doesnt matter what i do to the timing. i have put it to 18* and it is still there. if i get on it from a dead stop it is not there. i have tried all kinds of things with no luck. it doesnt pull timing and it is not audible.
