I have a 3 bar map installed on my car. My boost Gauge reads off from my map sensor i have tried 2 other boost guages. I seem to be a colum off lets say a 8 psi i am dataloging 6.8 psi. I have checked for boost leaks everything. What i am wondering is under the part where i select map sensor i select gm 3bar. under koeov section part wouldn't that change due to your elovation. I know with my key on engine off my voltage with a multimeter is not the same as that value crome has there. So should i change koeov to my voltage

 

Is the data log reading 6.8PSI or is the cel trace just showing that it is using the values in the 6.8PSI collum?

 

i have the same issue... my koeov is 1.3 on my 3 bar. would like to know how to fix

 

Tell me if this is correct My collum is 6.8 and the next collum is 8.1. so does that mean if my boost is below 8.1 i will read from from the 6.8 collum, that is what i have alway thought. But yes when i am boosting 10 psi i notice my cel trace will be in the 6.8 collum and my map datalog will read at 8 psi.
