EDIT that's as close as i can get everything to line up, anyone know how i can upload the actual excel spreadsheet?

[snapback]108298[/snapback]

ok well yeah 12 is low thats where your 4 deg. of knock is, your running lean around there, your 02's should be higher ,thats where its happening, get a AFC or power tuner and add more fuel at the top end, dont keep pegging the 4 deg of knock if you dont need to if its there let off either way your going to be going slower

use the sweet program my brother made..

phat_ridegt · Dec 25, 2005

wow nice program....

A negative fuel trim means the PCM is subtracting fuel to reach its target AFR. It appears you need to lean out the car a good amount.

Don't pay attention to the O2s without a wideband. Not going to help.

phat_ridegt · Dec 27, 2005

negative means rich, what i about the positive 71 or whatever around 70 mph~ could it be because its running rich

nitrous · Dec 27, 2005

That 71.9 looks like a display error. It is probably your MPH; the PCM doesn't calculate fuel trims that high.

phat_ridegt · Dec 27, 2005

you think it is a scanning error even though on the ls1m itself it shows that 71.9? how does the afc actually work? i mean how do i take away some fuel on the unit?

nitrous · Dec 28, 2005

I would say that it is a scanner error. If you look at the MPH on the same line it's 70.8 and then 73.9 on the line below it. Seems like the PCM had a "glitch" for a second and read the wrong parameter. If, in fact, the PCM could calculate/read fuel trims up to 71.9 you would probably suffer some damage since it would denote an extremely lean condition. That is if you didn't pop a piston.

To use the AFC, start it at 100%. That would be your baseline MAFF. To lean it out, go down 1% at a time (99% is leaner than 100%). To richen the mixture up, add 1$ at a time (101% is richer than 100%). Take your time! Cannot stress this enough. If you have to check your scans every time you lean it out, do it.

TTT

i scanned and leaned it out a bit with the afc, take a look at this one, it is with

TOGs and 3.0 pulley w/ race gas. the jumps in KR are due to wheel spin...why are the o2's running so rich but the ltft is gettin closer to perfect?

nitrous · Jan 8, 2006

Your O2s are not accurate. You need a wideband before you can really give the O2s any credit.

phat_ridegt · Jan 8, 2006

not accurate meaning the reading are not correct or they are off what they should be?

nitrous · Jan 8, 2006

The readings are not true (correct).

3800 will some look at this scan...
