I just spent several hours tooling around town to dial in my setup. Since my warranty replacemnet engine wasn't gettin it. I put the goodies back on (see sig) @ 200 miles!

Just before the former powerplant went down I had a custom Y-pipe made w/ C&L cats. With the addition on the worked over headers, custom Y and second gen McCord power cutout valve.. I had some MAFT adjusting to do. In the process I found I had picked up a fair amount of false knock. I did everything imaginable to make it go away but it stuck around at low levels 2-4 (degrees). I decide to try Tony's (Nine Ball) knockout box.

It was an easy install and the price was right!
With 1600+ lines of ATAP and approx 60 WOT I never had any occurances of KR at ALL! Nothin, nada, ziltch absolutely 0!

If ya wanna see my data in a web page form go here: (scan to right to see summary)** I removed all lines with less than 50% TPS to make it more viewable.

Glad I could help, Todd. Thanks for posting the results! I simply took someone else's idea about desensitizing the sensors, redesigned the wiring schematic and resistance values to remove the pesky ground wires, and packaged it up for myself. I was having a ton of Knock Retard issues when trying to run open headers at the track. After guys locally around here started asking me to make one for them, I realized that this could help out alot of people. Simple and effective, for a reasonable price.

Knockout Box!

Cant wait to see what it pulls man. It pulled like 380+ without headers didn't it?

Man, I just looked at your AutoTap data, WOW! I'm envious of those numbers:

LFTF B1 0 avg for fuel trim cells 1-19
LFTF B2 0 avg for fuel trim cells 1-19
B1 & B2 0 avg LFTF for fuel trim cells 1-19

O2 B1S1 0.880882 avg WOT B1S1
O2 B2S1 0.890392 avg WOT B2S1
0.885637 avg WOT O2's

Avg. WOT Timing: 29.35

KR: 0 occurrences (over 3 degrees)
#DIV/0! average KR (over 3 degrees)

-The last line cracks me up. I'm guessing the software that computes the average is not used to seeing a big fat "0" in the KR column, otherwise they could have programmed it to read "none" if there were no value. LOL! Awesome numbers, good job with the tuning!

Jeff,

I was very close ... but since I added headers, LS6 intake and a custom ECM from Ed Wright. I hope to see the good side of 400 rwhp!

Tony's knockout box was a clean 5 minute install even without the GM connectors. This is a 5 star product that isn't out to fleece us "rich" LS1 owners! <img src="graemlins/fluffy.gif" border="0" alt="[Fluffy]" />
