The FCON and VPC both use the same pressure sensors yes. So if you have an FCON AND a VPC you only need ONE pressure sensor, do not hook up both or the computer will be confused and may cause some other problems which could be misfiring and/or stalling (not starting?).
PS: Call HKS on it. maybe they could help you. I know they did for me!
Simann: Yep, I was referring to the boost pressure sensor. Thanks! As for the owner above, IIRC, there is in the fcon or vpc manual a check procedure for the sensor, to test using a voltmeter. I'm pretty sure there is. I couldn't find my pics on my pc of the instructions, but I coulda sworn there is a test for this...simann said:The sensor you speak of, is that the boost pressure sensor?
If thats true, I guess you should be ok. Though you could just use the one, plug it into the VPC harness which sends the signal to the FCON anyways, meaning there is not a reason for splicing the sensor.
See the FCON "gathers" the information from the VPC, meaning the VPC's boost pressure sensor is enough. You do not need two sensors.
So did you get the car running fine?
