Ecu voltage vs battery terminal voltage.
Apexi is reading about 0.3V less than a multimeter across the battery terminals both ignition powered before starting (less earthing current through ecu) and engine running (only tested at idle). Is this close to what I should expect or do i need to go chasing connectors/earths?
The main engine harness earth that bolts to the front plate behind accessories and front plate itself were cleaned up recently when i fitted aftermarket coils.

The ADC only has so many bits to store the voltage range within, which gets reduced even further when sent to FC-EDIT, so there's some loss in accuracy. I wouldn't worry about it unless its a significant drop.
