It looks like you just need much less deadtime. If the fuel trims are negative then remove deadtime/fuel. Simple as that.
You're right Marty. I didn't see that. I think he inputted the voltages incorrectly. He meant to do 1010 but probably typed 1210 based on my recommendations below.Nick, did you see how the injector offset voltage went UP then back down on his log? I agree with global (LTFT) and Deadtime (STFT) adjustments looks like all it needs.
Here are his values. 14 and 16 were so close, I am sure they should have a better swoop to them so this is what I would do. Just change the 16 volt to anything that makes the curve look nice and smooth (like my picture). Just my opinion is all. All of my cars swoop in that way, but all are different. If FIC gave the values, I would keep them, they just looked a little skewed.

Assuming you're running 43.5 fuel pressure
I must have been doing it one handed and pressed the wrong button. That shall be adjusted and check it out. 9v is a bit out also so shall i lower that to be a smoother line, maybe like 2444 instead of 2555You're right Marty. I didn't see that.

I managed to go back sunday after watching jafro's video a few times to understand and i still i got it alot better now. I shall upload the log tonight once im home. I got AF est and wideband pretty close to being on top within a few points and the STFT and combined is also within the 8% which frim my understanding is ok, 0 is ideal but for now baby steps for me . Once im happy with how i have to get good setup dialed in i will be more happy to go do other logging and perhaps get it on a rolling road to tune it fullyFuel trims suggest it is still to rich.
Stock cams yes for now anyway, wim working on a head with GSC S2 cams later on. I shall look at the AFPRev bits on the weekend if i can. I need to find time to go for a drive for a proper log but cars not road legal yet so its a bit tricky till i do thatLooks closer. Does the car have stock cams? air fuel per rev could come up a tad at some points it seems. If it had cams then it would likely need to come up a bit more.
