Does anyone have the ACTUAL Voltage Output vs Pressure of the OEM MAP Sensor on the 996 Turbo X50 or S?
996-606-180-00-M14 it is a 0 261 230 042


This is what mine reads, I just took it out and measured it on the bench with 5v applied.

1psi =1.92v
5psi = 2.53v
10psi= 3.2v
15psi = 3.86v
20psi = 4.5v
22,5psi = 4.84v

Thanks in Advance

The oe sensor is sold through Bosch Motor sports with a different part number. My guess is with a little "google" work, you can fine the specs of the bosch motorsports unit.

1.55 bar should equal about 4.9 volts... Keep in mind that the stock sensor can only ready to 2250 mbar, so your 25psi data is actually more like 22.5 psi.

 

You are correct: It is a 250kPa sensor as you say 22.5psi. There seems to be about a 10% Deviation on it though, or at least mine. I based my calculating on 19psi anyway as that is the extent of my X50 Flash.

 

So is this a 2 bar sensor then or 3 bar given ambient pressure?

It's 250kPa = 2500hPa = 1.5 bar boost.

 

I think it is 2.5 bar as 1 bar is ambient pressure so it reads 1.5 bar above ambient or 2.5 bar total range?
