TerryH said:A difference of more than 1.5volts between what is measured at the battery with a known reliable and accurate multimeter compared to what is displayed by the VDST software seems very excessive.
I know my electrical theory, I was hoping that someone else may have the same bike and the same software package who can compare figures.
We have done the testing with the bike running at 3,000rpm and the discrepency is still there.
Others have said the same.TerryH said:Some motorcycle ECU's have correction factors based on battery voltage as read by the ECU.
I'm not sure about the one in the Breva.
I am using VDST as a diagnostic tool which is it's intended use and expect the information displayed (including battery voltage as read by the ECU)to be correct or indicative of a system fault.
This is why I am asking the question if others have come across this discrepency.

alwyn said:At the end of the day the vdst states battery volts,if this is not displaying battery volts then change the display to show what is being read,if someone changed a component based on this equipment's reading would there? should there? be a comeback on the vdst team...is the tacho accurate,is the TPS correct?etc etc....
