you guys' that said to just switch the settings from bar to psi must be talking about the VAFC 2's since my old VAFC 1 couldn't switch the display settings, it only read in bar, and yeah my vafc was alwayse more accurate than my boost guage. A simple way to figure out bar-psi is just what ever bar it it just add 1/2 again and that will give you a ball park since 1.47psi is .1 bar.

 

ya mine's a a v-afc 1 also.

 

the vafc1 displays in kg/cm2.........which is slighty different than bar

easily converted with this calcuator

i haven't looked at my autometer in 2yrs...........------ junk


the best part of using the afc for a boost gauge is the peak/hold function

 

thanks for the info and the link to tha calc.
