Barometric pressure... potentiometer voltage

[samnumba1]

I know this is random.. Could a POT mod user, that got the signal perfect with no misfire, test the voltage going to the ECU because I'm using a very advanced potentiometer and i need an exact voltage that the ECU will see... I know the ECU will check for misfire at anything above 75Kpa or so....sooo I just need to know the voltage to represent less than that...

thanks,
Sam

Sam,

I know that this is quite a while ago, but have you ever got an answer to this? I was just wondering, because I am just playing with this stuff now. At 3.90 volts I still get a P0300 code after about an hour of driving, so I tried 3.70 and still got the code. I have just lowered the voltage to 3.00 and its been a entire day so far and no code yet. I am using ECU+ and it has built in "translation" so, I am trying to take advantage of it to solve my P0300 issue. I can feel the ECU any specific voltage via an analog output. The only thing I have noticed so far is that, at 3.00 volts, the car runs like shit until it warms up. I am trying to learn about the baro sensor and how this affects the AFR/mixture.
