BF150 Barometric Sensor

I was wonder if anyone knew the operational range of this device in terms of the pressure equated to voltage?
The manual defines a several voltages of the device (Voltage low, High, Shorted,etc) but at what Baro Pressure? (Sea Level?)
I'm looking for the Barometric value for the different voltages.
 
I guess this question stumped you guys.

How about if a cause the sensor to think it is at a HIGH Altitude, would that Enricken or leaning out the engine?

anyone have any experience at high altitude engine performance?
 
High altitude requires a leaner fuel mixture. Not sure how that relates to boat motors, being at sea level, unless you're on a lake high above sea level.

So I may need to make the ECM think we are below sea level. That might happen if I can't figure what is causing an over heating sistuation.

Another data point I have a new BARO sensor and on the bench it measures 1 vdc with 5 volt source. But when i power up the engine with this BARO sensor, I get an alarm. Swap the BARO from my good engine no noticable difference. So I'm guessing I need to increase voltage to 3 vdc instead of the 2vdc I have now.
