Added ARE stage II heads, T1 cam, FLP w/cats, SLP MAF
Car runs good on stock tuning

Used LS1 Edit to do the basics:
Gear ratio, Rev Limit, Fan on/off, CAGs disable, Remove O2 codes, Adjust Idle speed, Raise Torque Management etc

Atapped and found:
LTrims where in the +7-9% range the entire run
Timing was down to 25 degrees at some points so I adjusted to 30 based on MAF rate
Zero KR everywhere except 2 at ~4500 so I desensitized the Knock Sensors 25%.
O2s were in the .92-.93 range throughout the run.

Going to do some more atapping and lean the car out a little. Any tips on how you experts would do it? I love LS1 edit.

 

how did you desensitize the knock sensors by 25% i dont understand that part of ls1edit. I would reduce timing around 4500 before desensitizing knock sensor. I assume you made sure it was false knock. Want you to run fast for a loooong time <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

How do you MAKE sure it's not false knock?

 

run 100 octane and see if it goes away.b

 

Were your LTRIMS measured right after you downloaded the tune or did you drive it a while before that?

Also, did you see these values (+7-9%) on the WOT run? That would be strange. They should go to 0 at WOT. STRIMS should too.

I am sure it is false knock.
I made the Atap run at least 15 miles of driving after the last download.
Ltrims were in the +7-9% throughout the WOT run.
There was a thread about modifying one of the Knock tables by .75. Dont know if this worked yet but I will let you know.

Should the Ltrims be closer to zero??
