yeah, what big tex said, i see 24.5deg of timing thru the entire run and get 0 knock retard, my a/f ratio is right at 12.8-1

 

John, I see you peeping in this thread. Whatcha got to say?

 

While the tuner is suspect I think this motor just has major false knock problems. I need to get some Xylene and see if it still knocks.

Are you SURE there's not a nitrous bottle lurking under that bed rug?

 

hahaha...yeah, I got side tracked watching Southern Choppers on the Discovery Channel.

 

The nitrous is under the back seat, I didn't want to cut up the bedrug. Would a wet kit change MAF readings? Or for that matter have 0 KR on 29*s of timing? Nope. I have a seperate tune to run with nitrous.

I hope to get some good nitrous 1/4 mile times real soon. I'll probably do something about my stock muffler before I try though.

You should try one of Tony's knock out boxes, or even a resistor mod. It realy helped out my Z71.

 

wet shot drops my maf numbers by about 5lb/min, i bet tex is runing a 75dry shot to get those maf numbers

 

 

You guys wish. Explain the timing, low O2 readings, and lack of KR? No jump in MAF flow from a nitrous hit on that graph. Look at my IAT temps: 88*s. hehehe. Not even getting a boost from subzero temps. Sorry, NA all the way.

 

IAT wire cut and resistor of correct value placed for 88°, progressive controller on the nitrous to make it look N/A, running GOOD gas for high timing and low O2's.

It can all be explained Tex, now tell us the truth.

 

OK, you caught me. I'm a 15 year old student and I don't even have a truck. I'm just practicing up on my photoshop skills.
