If you can't find anything in this thread then I woud suggest starting with the settings on the FIC 1150's somewhere around page 44. Those are also the NON Bluemax style and the size is very close. As a suggestion I would use the 1150 latencies and cut the scaling back 1 or 2 then see where that gets you. You should be able to tweak from there.

Hey guys. I'm a slight newbie to larger injectors, scaling, latencies ect... I've read all 51 pages, took notes and just need to know one thing. I have FIC750's and used nj1226's posted settings of...
Scaling 650
Latency
3.312
2.04
1.296
0.792
0.72
0.504
0.336
After letting the car warm up and doing a 20min idle log my LTFT Low went to -6.5% then at the 16-20min mark came down to -4.9%. My STFT fluctuated between -0.8% and 0.8% for almost the entire time but randomly jumped around from -3% to 3%. My question is how do you guys determine your STFT, if jumps around randomly? Would I consider my STFT 0%? I realize I still have to go for a drive and log that, but I'm just trying to get a complete handle on this.

STFT should hover + /- 10%. Better yet is + / - 5%. So where you have it is about as good as it gets. Good job. STFT is the "now" adjustment based on the front 02. STFT will jump all around. This is normal.
Go for a drive and you will some some changes. This is normal. Remember, the goal is to get the LTFTs to remain + / - 5%. Once you are within this range then you are ready to start MAF scaling to really dial in your fuel trims.

Awsome man thanks! I read up quickly on MAF scaling, but I wanted to get one thing down packed first before I start another. I wish the weather was nice here today so I could log at crusing, guess I'll have to wait until tomm. This thread is an unbelievable wealth of knowledge.. Thanks guys!

EDIT: Found some info for the FIC1000's from JB on page 26 and PD on page 12. Thanks again.

RC 1200cc working amazingly on E85! (thanks to John Bradley for the base and Razorlab for the injector recommendation)
Scaling
622
Latency
3.6
2.304
1.728

Startup IPW

With that as a base I was -4% idle and .4% mid LTFT. Scaled the 25hz down to 139 and 50hz down to 151 (right around 4% less). I originally scaled the 19hz down, but set it back because it made startup worse and was not affecting idle.
Car runs amazing. Startup has been flawless and takes less than 1 crank down to 25*F (the temps have been between that and 70 here lately). My low speed bucking is also gone, for now at least... we'll see if that changes with the weather. I'm actually also getting slightly better gas milage than with the 780cc, and that has been with alot of reflashing and tuning different settings along with quite a few pulls. The last tank i ran was fully on this tune and it just keeps getting better.

Glad those are working well for you fostytou.
Curious of your peak IDC with those?
FYI the 1200's don't flow much more than the 1000's at the same base fuel pressure. I still have no idea why RC benches them at different fuel pressures.
