Battery Voltage reading in Tunerstudio (MS3-Pro)
Just curious, is there some reason the voltage reading in TunerStudio is .7-.8v less than the actual voltage it's receiving? For example, I can measure 14.1v @ the terminals powering the MS3-Pro with a Fluke meter, yet tunerstudio is only reporting 13.3v in the ECU. Same thing happens when the engine is off, 12.5v at the input, but the ECU is reporting 11.8v, etc.

Most likely just variance in the components in the circuit that reads that voltage.
I typically just fix the battery voltage by adjusting it manually until it matches in the settings.
