Ok before anyone tells me to get real engine managment...First let me tell you this is my beater winter/daily car and i don't care enought to tune it on a dyno so i got the safc.

Well i got the car street tuned to like 11:1 AFR's in bost and i can't reember low throttle on my wideband. Thats the best me and my buddy chould get it to with the afc. Well with that said here is the set up not that is probally matters:

sls top mount mani.
sls IC pipes
Ebay fmic
custom 3" Dp Ends at the firewall
T3/T4 50 trim 60./63.(i know it is big)
dsm 450cc
safc 1
stock fuel pump
and the mighty D15 holdin at 205K miles

FORGOT TO AD: the car is a 93' civic dx

So my problem is when i'm on the interstate and i'm cruising like at a steady rpm/speed i will pop a CEL if i don't every 10 sec or so give it gas to change throttle position??? Whats up?

And also if i rip it in like 3rd gear it will throw a CEL???? whats up?
finally i got the codes it has been throwing :
1-o2 sensor #1
3-map sensor
43-fuel supply system

if you are OBD2, you will throw a code 13 (baro sensor) and there's nothing you can do about it.

Everything is entered correctly.... so i'm at a loss

Might help if you told us what CEL it was actually throwing...

Update on the codes

1- o2 sensor #1

3- map sensor

43- fuel supply system

i'm putting in a walbro this weekend so we will se hif that will take car of the fuel code

i had the same problems but i had a reg. vafc. the o2 sensor must be just a bad 02 the map sensor is a bitch, i had the same prob even when i tried tricking it w/some prop valves so cant help u there, the fuel supply might be if u dont have a gas cap. i didnt, and then i got one and it went away. hope that helps a little.

I have a gas cap... so thats not it. <TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by 92eg6 &raquo;</TD></TR><TR><TD CLASS="quote">i had the same problems but i had a reg. vafc. the o2 sensor must be just a bad 02 the map sensor is a bitch, i had the same prob even when i tried tricking it w/some prop valves so cant help u there, the fuel supply might be if u dont have a gas cap. i didnt, and then i got one and it went away. hope that helps a little.</TD></TR></TABLE>

you had one the whole time? change ur fuel filter also

Schister66

hey i have an idea....install your Walbro pump already...that would get rid of 2 of those codes

1. it would supply enough fuel so the O2 wouldn't see lean condition
2. Fuel supply wouldn't be a problem

Again i have a gas cap and i changed my fuel filter when i put on the turbo kit.

#1, Because you are running so rich or so lean, the ECU thinks your O2 sensor has gone bad, it may have...it may not have. Fix last of these three codes...

#3, could be something to do with how the AFC is Effing with your Map sensor signal...check over the wiring, go over the setup again and make sure everything is working nicely. Fix this code 1st of all your codes

#43, your fuel system code means that the long term fuel trims of the ECU has exceeded boundaries that were preprogrammed in. Could mean not enough fuel pressure, code mean your injectors are clogged, could be because of an O2 sensor, could be (most likely) that your MAP sensor code is causing this code and this code is causing your O2 code. Fix this second...

i really think the vafc has to do w/the map sensor code, i had the same three codes w/my setup...bone stock ls w/revhard kit...stock injectors, stock ecu, w/255 fuel pump
