Installed Safc, Got Big Problem!

[RBFIRE]

Hi,

PLEASE HELP!!!

Big Problem I ran into while installing SAFC!

I followed PREDATOR's Instructions on the TURTORIAL section.

Predator got the Ground wire next to the Power Ignition wire, but in the Apexi ECU pin layout, the Ground wire is next to the Air FLow Signal wire. Does it matter about the difference?

Now i have got a problem.

the idle is rough,

smoke come out heaps in the exhaust.

and cant rev pass 2500rpm!

i tried to remove the SAFC wires to stock as b4, but still does same thing.

I did ECU diagnose and got CODE 12: AIR FLOW METER CIRCUIT,

so now, how can i fix the problem?

isit the ECU faulty?

what are my options at go about fixing the CODE 12?

please help!

I am panicking rite now!

thanks,

darrien

i have no idea of the guide or instalation, but i can tell you that the symptoms you describe sound like an AFM that is not connected

so when you saw that you re-connected it, it sounds to me that its not connected at all..

Waz.

Shit god damn.

I've got mine installed using the tutorial on here... and it seems to be working fine...

I dont know whats going on, i'm fairly sure that the circuit is grounded correctly otherwise it wouldnt be working yes?

Possibly the AFM wire is not connected correctly and its in limp mode.. its doing what it would do if you unplugged the AFM.

Maybe the AFM has been fried for some reason?

I'm scared now as i wired mine the way it says on SAU...

[Mr Italy!]

NOOO buddy NOO!

That wire is Air flow meter ground, not GROUND!

Ground is located to the right of IG power, as it shows on preditors!

Bad luck mate. My SAFC2 wire diagram shows exactly what preditors does too...

could i have done something wrong?

I panic when i saw APEXI website,

that they have the ECU pin layout, GROUND is next to AFM Signal wire.

I hope i didnt fried anything, just bad ground maybe.

but yea, its weird that 2 ECU layout are different!

I will re check again!

Did you disconnect the battery before you started to wire in the safc?

Did you have all bare wires insulated before you connected the battery?

Are you experienced with electronics, wiring, etc?

Sounds like your afm is either disconnected or blown. Or worse you may have blown in afm circuitry in the ecu.

How do i find out is my AFM blown or the circuitry in the ecu is blown?

- yea, i disconnected the battery b4 wire it up.

- i insulated them, soldered them as well,

- and yes i am know abit about electronics, i work with them all day. telecommunications equipments.

but for automotive, am only know basic.

how do i go about fixing it?

worse case scenario? if I blown the ecu afm circuit, wat should i do?

just incase if it was just a simple AFM disconected?

how do i fix it?

do i just check for connections?

first i thought maybe the bullet conectors,

but i test for continouity with the meter, and it is.

where to start to find out the problem...

any helps please?

thanks,

anyone???

where can i take it to? to get it check and fix?

thanks,

Take it to an Auto electrician... its their field of work.

[wildr33gtst]

same thing happened to mine, a mate didi it with me you have the air flow meter in and out the opposite way, it worked when i changed them around.

[RBFIRE]

problem Solved,

that was 4 hrs wasted!

i turned out to be the connector to the ECu pins,

its loose,

so i didnt get connection from the SAFC to the ECu at all, everything else was fine! ONLY the connection b/w the ECU and the AFM output signal was loose.

Maybe when i was wiring it, might pulled it too hard!

Problem FIXED, SAFC installed!

sweet! thanks ALL.

...and you doubted predator!

the whole point of the site is to share our exprtise with others.. if someone takes the time to write a tutorial (especially someone like predator) then they usually know what's going on

glad its all sorted and hope you get a good power increase!
