Re: LTFT'S at 25%. How to lower with edit??
 

go to the MAF button on edit.. click it.. over in the bottom right of the table grid that comes up you will see a MULT % box... fill that in by 115 and mult the whole table. That wont get you to 0 but it should bring them down to +4 to 5(better than before)

mine where +23 and i mult the table by like 117, then came back and mult the cells almost all the way over by 104(then the next cell i dowscaled going to 103, then next cell to 102, then 101.. then stopped).. btw, if you do that make sure you click the mult selected cells only grid)

but i think my car didnt like mult the whole maf by such high numbers, so 110-115 would be the the max i would go...

this is also another format i did ona friends car and it worked(from someone off of here)
"I was running between 15% to 20% for the Ltrim fuel on my '99 SS.
I'm assuming that you have LS1_Edit.
With LS1_Edit, I would do the following changes to the MAF table:
1500Hz to 6000Hz: multiply by 120%
6125Hz: multiply by 119%
6250Hz: multiply by 118%
6375Hz: multiply by 117%
and so forth until you multiply by 101%, then stop
Flash this new program back onto your PCM.
This technique reduced my Ltrims down to a range from -5% to 0%.
Do a PCM reset and go out and drive the car around for about 15 minutes then do some ATAPing."

Thanks alot for the tip's. I just multiplied the entire table by 103. I went out started the car they were at 0.0%. Plus it started and ran smoother...you could smell in the air I was running supper lean at idle.

While I am driving...what should they(LTFT) be reading?

you dont go by the ones at idle <img border="0" title="" alt="[Razz]" src="gr_tounge.gif" />

log your LTRIMS while cruising around for 10mins or so.. then average them. Thats what you will need to go by when mult the MAF table <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

but you have the hang of it so you know what to do now. Just work your way accordingly and see how it goes

I am still learning ls1 edit. How do I lower them to 0 or negative with ls1 edit?

Thanks Jason
