Hi, I am using my i3 for diagnostics on my 2011 Chevy Silverado 1500 4X4 5.3 and the displayed fuel pressure is around 100 kPA, however the pressure at the fuel rail reads 42 PSI when tested by my dealer.
Why the difference? Converting kPA to PSI gives 14.5 PSI for 100 kPA. Am I doing something wrong or is there a problem with the DataViewer app? :( :(
