I bought an FCon for it. It came with its own boost sensor and I hooked it up. I still have the stock boost sensor as well. If I unplug the stock one, the stock gauge will not work. Do I need two boost sensors on this unit?

Also what should I set the FCD to? I have the HKS one.

Thanks

Yes, you do need both boost sensors - do NOT unplug the stock one. The boost sensor for the FCON is so it can see how much boost the car is actually running so it can make a fuel curve for it.

The FCD should be set up right as-is. If you hit fuel cut, it isn't .

the FCD should be at 7

 

I have a question for you. My freind has a car with a fcon and the fcd with it. I need to know about the boost sensor that came with the fcon. There is a blue, green and white wires that come out of that sensor. Here is the problem, when the last person took the fcon out, they cut those 3 wires and I where those 3 wires go. Can you tell me where i put the blue. green and white wires out the boost sensor?

Thanks

 

Nevermind, I found the instructions online and the wiring diagram solved this one.

 

where did you find it? please pass it along. I'm having the same problem.
