There's alot of posts here about SAFC.
SonicRat helped me out 'coz I got a little confused.

What kind of starting problem? Click? Crank?
You probably wired it wrong or set it up wrong, I don't know, coz mine started right up

Are you sure you wired it right? or Set it up right? Where did you get the info on how to wire 'em up?

Which ECU?

I don't think this device has anything to do with fuel or spark.
More like Air. correct me if I'm mistaken

I have this:




For your first question, you must take the stock wire that goes from the ECU to the AFM (the pin they have marked), and cut it completely in half. Then you attatch those wires to the SAFC. The side of the wire that runs back to the ECU is the Yellow, and the wire that runs through the rest of the harness to the AFM goes to White. Though, I can't tell you exactly if these colors are correct it's been a while, but I just reused yours so you could understand better.

The grounds are kind of special. They must be soldered or spliced on to the ECU's ground wire with a gap between them of roughly 1cm. This is rather important, it helps to clean up the signal from the AFM and keep the SAFC more precise. The order if I recall isn't important, but again, APEXI has a generic manual on their website which will describe this in better detail to download for free, so it would be best to consult the manuals first. But I'm pretty sure that's how it goes.

well you are correct. it does just deal with air.. but i mena iwas cutting into the ECU so i know none of the wires arnt connected all the way... .
it just doesnt start.. my wires are correctly wired.. ( i got it from the APEXi site ) and does the ground have to be about 1cm or can it be more.?

You spliced on to the ECU wires. Make sure you twist the SAFC's wires tightly on the ECU wires.

Did you set the SAFC right (Settings)?

What do you mean it just won't start?

If I disconnect my battery, that won't start.
If I empty my fuel, that won't start either.

When you twist the key in the ignition to 'start' - what happens? Is it cranking or is it not?

You might have to re-check your wirings and device settings.

Whatever it says on the manual. If it says 1cm, I'd do 1cm.
