(originally posted last night (8/9/06) on dsmlink forums...)

whats up guys, its been a very long time since i've been on ... ..well, about 6 months ago i stopped any type of racing....mostly ### i've been concentrating on my new setup (fp3575, 6bolt, higher comp pistons..(goin a lil higher than 8.5, could be hard ) but thats another story...

so for the last 6 months, i haven't bothered even lookin at a log....mostly due to moving...blah blah, u know....so, i just recently started loggin again, and i wanted to start with my LTFT's....i've been fighting with it for about 1 week and a half or so....i just can't seem to get them within 5% of zero....this is my most recent, which i dont think is to bad of a log, (feel free to lemme know anything u guys might see wrong)....but notice my global settings...

LTFT Lo = -2.8 or so
LTFT Mid= -8.4

but my global is at -28% and deadtime of 285?? these are on FIC 650's with a 255 fuel pump, with stock regulator(i know, i can't wait till i get the adjustable....) and the pump is rewired... what do u guys think??
 
hey guys wats up....guess noones replied yet... ...LOL, i know i gotta give it some time...

well, lemme makes sure i got this right....if your LTFT's are unequel, but LTFT lo is higher then LTFT Mid, then u have to increase deadtime right??

well i did that so my deadtime is now at 315 with -28% global....
this is what i got after a cruise and a long idle...
LTFT Lo= -6.1
LTFT Mid= -10.9

so heres what i guess i'm gunnin for now...increasing deadtime until there both about equal, then using the global to get em near zero....right??

but these are my readings with a 315 deadtime and -28% global....does this seem right?? if i keep tryin to get em about the same, then i wouldn't be surprised if my deadtime went almost to 400....that seems very high for FIC 650's....can it be ### i'm still on the stock regulator?...another thing...lets say i get em close to each other... and i add fuel to get em near zero (my moving positive on the global slider right??)...that''ll be almost 10% i have to add...is that right??....please help....thanks

MODS: big 16g, FMIC, intake, 3' DP back exhaust, FP1 cams, re-wired 255 pump, FIC 650's

P.S....i do have logs, there on the laptop tho, i can post em up later..
 
Try these settings I found for FIC 650cc injectors: -31 210
I used some settings off of the same chart and my injectors are almost on the money now :thumb: . Hope that helps you.
 
I have FIC 650's with 180 LPH from a VR4 with stock regulator. Global is at 30 and deadtime is at 330. The AFPR should help you out a lot on smoothing out your trims. I hover around -2 to 2 on mid and -3 to 3 on low.
