2g safc tuning help!!

[slowrb20]

Ok.. I've searched and read many threads but cannot find any one that posted there maps with the same mods as me.. Also I tryed to input my setup on Dsm tuning guide 2.1 but was having issues.. Every way I try to go with it it runs like poop..
Need suggestions for fuel correction at hi and low and am using 1k 2k 3k 4k 4.5k 5k 6k 7k as ne points.. Ive tried setting hi at -18% as it says in the beginners tuning thread as a starting point but it cuts out terribly at wot.. Any help is greatly appreciated..
2g gst
Greddy 18g ,small greddy fmic ,550cc injectors,255lph , fpr ,safc 2 ,wideband,act 2100 and act flywheel stock exhaust and dp..
18psi
50psi base fuel pressure
And I'm using my iPhone to monitor data.. I can't log but it shows real time data so I can monitor stft, timing, and afr with wide band

Sorry I can't answer your question, I am also in the process of tuning my SAFC, but just curious, how do you monitor that with an iPhone? I would like to get that app/wiring

1. Why is your base fuel pressure 50?
2. What does your wideband read?
3. Please get a way to attach a log. You are basically asking us to guess on incomplete information while you check.

Base fuel psi should be 43.5 for a 2g. Do you happen to have an AFPR for that 255 fp? (adjustable fuel pressure regulator)

Wideband should be telling you a ton. What does AFR read at idle? What AFR read while cruising? What does the AFR read while going WOT? (AFR = air fuel ratio)

What afr's are you showing?

mine was tuned in at 20 psi,and i have a couple diffrent mods but i figured id still post my tune on here. also im not sure about the tuning of your s afc im useing a apexi neo but
rpm 500 1000 1500 2000 2500 3000 3500 4000 4500 5000 5500 6000 6500 7000

hi th 0 0 0 0 -10 -25 -35 -35 -35 -35 -35 -35 -35 0

lo th +5 +13 +10 -2 -2 -2 -5 -7 -7 -7 -7 0 0 0


also my low th is set at 15% and my hi th set at 80%

and then my 500-2000 tune i think got changed a lil bit somehow.i havent been driving the car since its winter but this tune did pretty good for me. it wasnt perfect but i ran at about 12- 12.5,but im selling my afc and getting ecmlink. its pretty hard to get it perfect with a afc. it took me days to get that tune.

hope that helps.

Yes I have an afpr sorry.. I read on another forum to run 50 base fp.. And there's a chord u can buy at wal mart made by a company called go point that plugs into your data link connector..
For some reason my afr at idle is way lean at around 15.5 but if my stft is at 0. And if I adjust the safc at idle to go richer it will stall and run like shit.. I haven't even cruised or done a wot pull because it's running that bad... I'm checking for vacuum leaks and boost leaks as I'm posting this.. I'm going to lower base fp and see if I can get my afr at idle down to 14.5

From the issues I recall having with an Apexi, make sure the basic settings are correct:

1. Karmen sensor reading
2. 4 cylinder
3. Arrow pointing northeast.
4. Plug in global settings for 550 injectors

If everything is wired up correctly, it should run fine with zeroed out settings.

Your fuel pressure regulator is adjustable, correct? If so, what is the gauge reading at idle?

 

[slowrb20]

At idle with vacuum connected? Or disconnected? And what you mean by plug in global settings? It's an safc 2. An older model I do believe
