First of all , thank you so much FAST_FREDDIE for creating this thread.
Just installed a new turbo kit , waiting for injectors to arrive.. so i decided to apply these settings with stock 560cc injectors. ROM in use is 96530706 on e7 ecu. Tried flash v7 90550701 bt the car didnt start.
Kept lowering the scaling till 463 when the WOT AFRs matched AFR MAP with a difference of .5 or less.
Fine tuned it with MAF compensation table. The idle STFT is ranging from -1.4 to -3 while cruising stft hovers bwtween +4 and +9. There are couple of things which i noticed that aren't right.
1. Car takes 3 cranks at cold start and 2 cranks when warm, [ which table needs to be adjusted, cant figure it out
2. Starts up rich AFR 13 then goes to 10.5 then after 4 minutes comes back to 14.7 -15.2
3. 4th gear, cruising , part throttle car in vacuum hitting 11 AFR.
4. Is is this particular rom has some embedded issues in it ?
Which tables i need to adjust in this rom to get it IDLE, CRUISE better and get rid of this crappy cold start issue.

Does anyone have the scaling/latency settings for Black-ops 1400cc injectors? Doesn't look like they are used much on Evo's?

HELP: FIC 1000 Questions NEED THE BIG GUNS PLEASE
Hi, it's been a while guys. Finally got the car to a point where it looks like most kinks are worked out. I am finalizing a tune done by a gentlemen in SLC. It needs a little work. It put 450 down on the dyno, but is capable of more. I have a build sheet of everything done to the car on here somewhere. Either way, on to the questions.
How do you interpret the calculation in Merlins guide for calculating injector size utilizing the HP = cc/min /5? Give me an example please. I'm wondering for how my injectors are scaled currently. Smells really rich at idle, gas smell in exhaust, Seems my scaling and latency is very high for this injector and very rich. I need to actually get a log with this, but I look at the Fuel map and it looks rich everywhere as well, as though its being compensated. I have successfully tuned a fuel map, and gauge AFR within .3 before. I guess what I am saying is that I don't think they are scaled properly. But then I don't understand the equation and how it relates to actually finished scaling. All the data listed under injector size scaling and latency in Merlin's guide don't give HP numbers achieved. It seems that HP value desired determines size scaling. This suggest that any number you put in for the scaling, you tune the latencies accordingly. Maybe I'm not being clear. I thought I understood these things, until I looked at that equation, and the 3 others listed with it. Please look over the info below and guide me in the right direction.
Thing to note with voltage: I have a Odyssey 1400 AMP Battery, with 160 Amp Alternator. I run 14.4V all day long.
FIC 1000cc Injectors
Current Scaling: 1044
Current Latency:
4.6 - 4.992
7.0 - 3.264
9.3 - 1.968
11.7 - 1.416
14.0 - 1.224
16.4 - .888
18.6 - .648
Suggested scalings in the guide as well as this thread:
FIC 1000s
scaling 860
3.312
1.68
1.344
1.152
0.84
0.36
0.24
What are the HP ratings of this scaling? I would assume by the equation listed that it would be less...
Thanks in advance.
