Its either 2-5 or 2-6 and you run single. Twin are for 2 MAF setup aka RB26.

I would suggest you sell the AFC and save up toward a Power FC.

The AFC adds additional resistance to your AFM wiring which causes very WIDE variations in Air Fuel Ratios.

You will also notice that there is a sweet spot once you start tuning the AFC and only certain couple of parts of the map can be adjusted. On top of this when you dyno and AFC equipt car it is totally impossible to get a smooth Air Fuel Ratio.

Either way if you are interested I can build you a how to sheet with a step by step way to configure your AFC for the best possible power and settings to get the most out of it while you still use it. It is very simple, pm me if you are curious
