I should have said 1 degree starting at one count, then another at 3-4 counts, etc. My point is, you'll see slight timing fluctuations even if you're experiencing only 1-2 counts of knock.

With 4 counts of phantom knock, the timing fluctuations would become quite annoying.

I certainly hope that set of forged internals doesn't mess with knock detection. I had a massive phantom knock problem on my last Mitsu, but nobody had figured out the knock filter tables for it.

depends on the builder and their tolerances, but like I said we _can_ adjust the knock sensitivity...

The affect is additive, so if you get a BUNCH of 6+'s then the ECU will move more and more towards the low oct maps..

Yaro - I agree with the others, 1-4 is nothing to be worried about, if you were consistantly getting 10+during a pull and you know it was false then we can fiddle with the maps...

...I wish I would have said that. OH wait I did.
