I have ls1 edit and efi live v5.
1. how do I convert lbs./min. to grams per sec.
I currently have about 25* timing at about 5500rpm, but at 3000rpm I only have 15*
Also when I go wot my ltft don't go to 0 like they used to, why is that?

For example if LTFTs are +8% (average )then you want to ADD more fuel . Scale the entire IFR table by 90% - the PCM will "think" smaller injectors and add 10% more fuel to compensate. Then rescan and watcth the LTFTs values change as the PCM learns/adapts. The PCM should reduce the LTFTs into the -2% range (for example) after a "learning" period. Good Luck.

MAF is global in function...fuel, timing etc. IFR is fuel only . My $.02. FWIW.

ya seems to be alot of debate whether to scale the injectors or the maf.....
prior to going bad the cars was parked for about a month. I switched lids and went with an amsoil air filter. took it out the first night. my ltft was about +14 cruising and wot timing was 13*............ before ltft were almost always -2 and timing was about 26*. I have an slp 85mm maf, my car never ran all that great with it and I was always getting a trouble code for low sensor voltage. Gonna switch back to a stock descreened!

Using the IFR table based on binks advice last summer worked GREAT for me.

slowhawk............ your harlen right
I've tried to get ahold of you in the past. I have one of your stutter boxes and it craped out on me. The car won't run with the box hooked up, one whole bank is misfiring, should I send it back for repair or buy a new one.
thanks.....love the product
