thats my file i been working on...as of end of last ngiht i have spark advanced 20degrees in most areas. still working on getting rid of KR completely. just dont have the gas at the moment wasted a lot last night. 1st and 2nd gears pull amazingly and ZERO KR...but i wish i could say the same as 3rd gear.

I was also able to advance my timing way past the stock tables, and by pulling a degree or 2 where it knocked, eliminate KR as well. I found that the taller the gear, the harder the engine has to work, so the more prone to KR it is, but that's where you want to get rid of it the most as well. Have you started playing with your AF's at all yet? Don't get too carried away with spark advance, as tempting as it is, because if you end up leaning out the power curve from stock, you'll have to readjust your timing all over again to get rid of the KR under leaner conditions. I'm now running regular gas, and running far more timing than the stock tune on premium would allow, and only had to drop 1-3 degrees in various parts of the powerband to eliminate KR over my HO PE table.
Really wakes the car up though doesn't it?
15.3 @ 89.97mph, 14's on the way?

please explain....i'm just doing normal spark advance until knock is picked up then drop the spark back down 1-2degrees... as for leaning out my mixtures to much my a/f ratio guage isnt reading anytihng different at all. i did adjust my a/f setting look on the file its there... if i blow it up thats on me and i'll fix it. so please i started this thread for some thoughtful input not BS...so please dont bother posting if u dont have some insight...thank you Ian for ur response

GM did not install a knock sensor as a "tuning aid". Nor does it function as any sort of a tuning benchmark.
Tuning by monitoring knock retard is not correct in the slightest.
20degrees over stock is simply wrong.
I am not the slightest bit inclined to waste my time writing a paper on timing's effects on combustion, just to make it clear to you why its wrong... so I won't.
If that annoys you, so be it. If you want to call it BS, you can do that too, but people who know me know I don't post BS.
