Well like the title says, I can't figure out how to lean out my car without LS1 edit. I have a MAF translator, but it only made the car run more rich even with it turned full lean. So I took it off. I have a SLP 85mm MAF. I am running about an 11.5 AF ratio. I have to check the dyno sheets at home to see for sure. Any help would be greatly appreciated. Also if anyone knows of a shop with LS1 edit near L.A. please let me know.

You can use the AMFT to lean the car out it works... maybe you went the wrong way with the switches.

 

If it's already lean (+LTFT) then leaning out
further will only jack up the cruise LTFT and
lock it in at WOT, dumping more fuel, not less.

If you found a buddy with a Predator you could at
least do a little monitoring to see if this is
what's up (can't touch, but can look with someone
else's Predator).

 

Put the stock MAF back on and try again.

 

any other suggestions?? How much horsepower can the stock maf carry??

 

prolly the same as the SLP 85mm MAF (isn't the opening to the intake manifold only 80mm?)

 

I don't know the opening to the intake manifold. Is it the same for the LS1 and LS6 intake manifold???

 

the opening on the ls1 and ls6 manifold and throttle body are 75mm. according to my ls1 ls6 performance book.

 

anyone else have any suggestions?? OR perhaps where can I get LS1 edit. Thanks.

 

you can get ls1 from carputing.com, it costs $550. i would go half and half on a 2 vin cable it costs $750, but i think you only get one cable
