high settings:

-3, 1, 5, 8, 11, 14, 16, 17

low settings:

30, 25, 14, 14, 14, 14, 14, 14

( 1000, 2000, 3000, 4000, 4500, 5000, 6000, 7000 )

How can you run so high on the high setting on stock injectors without hitting fuel cut? If I run +2 on my stock 450's and 255lpm and 14b I hit fuel cut.

Ok, heres something for u 1g guys, that have a 2gMas and AFC, w/stock 450's ( i re-wired my fp too ) . I must stress that u guys need to have a Logger so that u can monitor ## o2's and fuel trims.

Here are my settings on 14b @ 16psi , w/ 2g Mas, N1 3" turbo back exhaust, 2.5 uicp, and licp.

LO
1k - +18%
2k - +12%
3K - +8%
4k - +8%
5k - +8%
6k - +8%
7k - +8%

HI
1k - +10%
2k - +10%
3k - +4%
4k - +4%
5k - +4%
6k - +4%
7k - +4%

TH% 30/70
4cyl arrow northeast

At 1st I started w/+25% fuel at 1k @ idle oviously, and took away fuel until it brought my lo fuel trim near 100% and my idle was stable. and also started w/+15% @ 2k rpms, and slowly took away some of that too. U must have some sort of logging device so u can get things in some what normal cnoditions, until u can get it tuned

i just got my safc2 in my car and im just now learning how to work it.
i was hoping someone could give me some good base settings for my car according to my mods as follows.
1g awd auto 15psi
2g mas,b16g,650cc injectors,afpr,2g exmanifold,stock exhaust,255 pump.
what should my fp be set at?
what should my egt's be at?

[Green93TalonTSi]

can solve all of those quetions, but I can point u in teh right direction ( sorta ) well the 2gMas flowx 20% more air than the 1gMas, So if u add 550's ( i now u have 650 ) ull equal it out, 20% more and 20% more fuel. Well U have 650's, so u If my thinking is right, u just added 40% fuel ( correct me if im wrong, )will ###### need to take away some fuel, like 20%. Do you have a logger ? If not, GET 1 , or borrow 1 from a friend or another local DSM'er, once u get ## logger, and start to look at what the engine is doing, and go from there. U need to watch what ## o2's are, and atleast see what ## fuel trims are doing, u want to atleast set ## low fuel trim as close to 100% as possible, the idela range is 100-115% on the low. From this point I cant help u to much more as I dont ahve the mods u do, and every car is different, but what I had to do ( on stock 450's ) was add 25% @ 1st, and slowly take it away till my low trim and idle were smooth and as cose to 100% as possible. So, what I would do is start with -20% fuel and see what happens only do this if u have a logger , or know some1 who will let u borrow 1 ! Good luck.

should i turn my fuel pressure down to compensate for my new fuel pump? ive heard of putting it around like38psi. i have a logger im just now gettin the hang of using it.

[Green93TalonTSi]

I honestly dont know about Fuel pressure, might wanna run a search on that. Id like to know what to set the fuel pressure at too, as seeing i just ordered my afpr

[Cnock]

so should i just put the fuel pressure to stock which is around 37 if im not mistaken. correct me if im wrong.

[larryriverside]

i have a 60 trim turbo, 660 injectors, 255 lp, 2g mas, fpr@40 psi, and fmic. i run 20 psi of boost on pump. i know that i should be in the negitive on the high setting, but if i try to go there my cars spudders. i let off right away. also my o2 leans out bad. i am guessing that i should be like -15 or -20, but i just think its gonna blow if i go there. and yes i start to get knock. but i have been told that i have black smoke comming out the exhaust. and it seems to run way richer when i am driving on the highway. thats when the guy saw all the black smoke. any ideas? plugs aren't black either.

[larryriverside]

i figured it out, but thanks anyway.

Hey iv had a surging idle problem for the last 3 or 4 months. Brought my car into many shops with no avail. i called the original owner and he asked me if the battery had been pulled and it occured to me that maybe when the clutch was replaced they pulled the battery. anyways he asked me what my s-afc settings were and i had no clue cause i know nothing about this stupid thing but i looked anyways....


looking @ the rest of you settings im drawing to the conclusion that mine are... very wrong =)
hear they are...

thank you very much


Note: I do not have upgrade Injectors just upgraded turbo... not quite sure why this unit was installed in the first place. but no engin mods that would require this unit

Also: =) when im driving with the moniter on 4 channel the first reading on the airflow always reads zero.
i had my mass air flow sensor replaced but that did nothing

[Green93TalonTSi]

1st of all need to change those throttle % , it should be 30/70 and the 4cyl arrow up. that might help some , it would also help if u told us what ## mods are, cant help without knowing what u have done to the car.
