Like the topic says, do any of you know or know of a link that lists the exact voltages the map is putting out for the 25 vac/boost coloumns that the stock table has? is it perfectly linear so that i can take 4.9 volts and just divide by 25? What voltage does the first coloumn of 26inHg start at? 0V or .2V?

 

I would like to know too. I tried extrapolating the figures and they're WAYYY off, so i must be doin something wrong.

 

I think blundar explained this in the second turboedit class, go in the engine management section and look in the second te class thread, they logged it. Or just ask blundar

 

They jsut talked about what idle voltage is from what I could find. I need to know exact Voltages for exact vac/boost values.

 

Honestly, it varies in each car a little. Take 2 accurate readings.

Reading #1 - idle (Full vacuum)
Reading #2 - Key on/engine off (Atmospheric Pressure)

Plot them on a straight line and go from there. You can find any point on the line. The key is that the readings must be accurate.

 

full vacuum - 28" vac - 0.31v
ambient/off - 0" vac - 2.9v

In my obd-II integra, anyway.
