does anyone have a tune for an 04 s2kwith an aem fic 1912, so i can at least drive it safly to my tuner??

Just set all fuel cells to -50% and when you drive it, keep it in closed loop and it will be fine. I'm running an F/IC with ID725's and -50% in closed loop is really close to ideal. Good luck.

 

even in boost?

 

so what just go to the fuel map and put -50% on everything on that map?

 

As long as you are only running in closed loop, the ECU will read the O2 sensor and compensate to give you the correct fuel even in light boost. Your final fuel map should be around -50% from full vacuum to 0 boost and then start tapering to ~-10% near 10 psi.

Setting the fuel table to -50% across the board should only be used to get to your tuner. Keep the rpms and throttle position low and you will be fine. You could add a generic timing correction like subtracting 1 degree of timing per psi of boost but I wouldn't worry about it as long as you drive as described above.

 

but he has an 04 and i thoguht those had narrow band o2 sensor. if what i think is true, this would be catastrophe.

oh well, personally, i would contact the tuner and ask for a base map to load in. or flat bed the car there. thats really your best option.

 

^Agreed, asking the tuner for a basemap is the best option.

Narrow band still works for O2 feedback when working in the very near stoichiometric range. It's fairly binary in that it reads higher than stoich or lower and makes adjustments to compensate so it will constantly bounce back and forth just like it does in stock form.

If you keep the car in closed loop and generally out of boost, all you need to do is compensate for the injectors which deliver almost exactly twice the fuel as the stock injectors, hence the -50% fuel correction. This all assumes you are using the stock fuel pressure.
