Hey all. I'm in the middle of an install of a PLX r-300 in my car. I have it in and it's working [separate write up to come, just gotta chase a couple of gremlins! ], but I have a question....

In order to interpret the analog signal coming from my MAP sensor, I need to map out the voltage readings at different pressures. I need the ability to convert voltage readings from the signal into pressure units, in order for the PLX controller to work its magic.

To do this, I see two options:
1) To read the voltage at idle [and set this as '0'] and read at some random load and let the computer fudge the response curve. <- Quick and dirty method [I don't really KNOW the pressure at any point without access to other obd-ii logging goodies...]
OR
2) To either find the manufacturer of our MAP sensor and then track down the specs on the sensor or to find someone who knows the specs already. <- The elegant way...

So, does anyone know the manufacturer and part number for the MCS's sensor? Does anyone know the specs on the sensor? How many bar? What will it read at ambient pressure? Under xyz load?

Or, does anyone have another idea of how I can approach this?

Thanks, in advance, for any help. Have a great one!
