I've checked all my connections serriously like 10 times, my safc is hooked up right, it works, my injectors are in good, and my resitor pack is all hooked up good too. I put it on a wideband last week and my afr was like 10:1 and 9:1 at times just running at cruise, not in boost! My settings on my safc are lo- -50% at 1000--2000rpm and -44% at 3000 and -40% at the rest, and hi -40% all the way across. With those settings, in theroy, I am actually running LEANER than stock at idle and low rpm's, but the wideband said I was running too rich, I could even see and smell gas sputtering out of my exhuast. Bottom line - My injectors are spraying too much fuel under both open and closed loop control. I have no Idea why, can anyone with more understanding give me some guidence?

make sure you have the map wires right going to and from the AFC.. My friend had his switched and his car ran just like yours

pa2play

map wires?? what's that? I didn't see anything in the manual about that.

Slammd Sol

Are you serious?

pa2play

Serrious, I'm looking on the apexi web page RIGHT now http://www.apexi-usa.com/produ...e.pdf and I don't see anything that says Map, remember this is for a S afc, not V afc

Slammd Sol

im assuming you have a 92-95 civic cuz of ur avatar..

Slammd Sol

Assuming you have the wires correct - make sure u have the settings correct under the ETC. menu..

Make sure you have Pressure sensor selected with 06 in and 06 out

pa2play

yes, that's the diagram I used and I am ALMOST dead positive that I didn't switch them, it's raining out right now, so I'll check in about 10 mins and post back. So your friend was running WAY rich too with those wires switched?

showtymers619

did you put a resistor box with your 450s? .. also go all the way -50 to get it idling rite.. 450cc is actually 80% larger then stock .. which means at idle you will be running 30 percent rich even if your put it at -50 on the safc

Slammd Sol

yeah, it ran just like urs.. very rich and gassy. Make sure u have the pressure sensor 06 in and 06 out, thats critcal. I accidently forget to set those one time after i reintilized the AFC and it ran really really shitty too..

pa2play

just went out and checked it, and it's all wired right, this is so frustrating! because until I get this fixed, I can't drive my car!

Slammd Sol

u check ur sensors on the AFC?

pa2play

checked the sensors with the car Off.
In-1: 2.76 V
In-2: 0.06V
Thr. 0.475
with the car started and not warmed up
In-1: 1.08
In-2: 0.03
Thr. 0.475

ok, got the #s, what do they mean?

Slammd Sol

have u even glanced at the AFC manual?

speedworks

6 in-6out, 4cyl throttle up. i used an s-afc on a crx with 450's last week and just had to use a 23% negative correction. i could easily lean it out enough to kill the motor.

refer to Pages 24 & 34 in this manual

well, my in # is over .06 but my out is .06, should I reinitialize it to reset it all to 0 and start al over?

speedworks

if they are not both set at 06 then that is the problem. just reset the #'s then reinitialize

pa2play

ok, I reinitialized it, and then I started looking at it more carefully, and I realizewd that the press sensor was set at in 06 and out 06, I actually did a sensor check which gave me the other numbers, so ****, who knows what it is now untill I get it on another wideband. I really don't feel like driving in the dark with my a/f ratio.

is that ture? Because i always thought it takes longer for the DSM injectors to open, and on the SMC instcutions it says set idle & 1k to -(30-35), where as 2k+ around -40, to tell you the truth my setting is 34,34 and when its in drive and i'm stoped the autometer a/f reads perfect in middle (won't go to red or green), but when i'm in park/netural (auto) its rich.

pa2play

Does anyone else have any suggestions? still haven't pinned it yet.

showtymers619

my suggestion is get new injectors.. soemthing smaller then 450's.. you obviously dont need it.. get some 370 cc

cyman83

but afc hack is made for 450cc injectors.
