Hello, I have a friend with a Bosch 4 BAR sensor part 281002576 and uses a GFB EBC. The GFB device shows boost at 38# however in the MHD log it only shows up to ~32#. I know most likely the issue if the MAP sensor needing to be calibrated correctly. Does anyone either have the data sheet for the sensor or know what the min & max voltage and the boost range values for the sensor?

I have done a lot of Googling and have found multiple values but couldn't find the data sheet or someone saying exactly what the values are.

I also searched this forum and mostly sway bar posts where the results.

does it come stock in any cars?

I don't know what the sensor came stock on but I ended up getting the data sheet from Motiv last night.

well, then that solves it)

Well, still trying to get the values right, but I at least have something to work with. Would be nice to hear back from someone already using the 4-bar MAP sensor.
