Fuel Flow Calibration in a Suzuki Engine Interface
The default calibration for the Suzuki Engine Interface is adequate in
most cases, but if Fuel Used readings are off by more than 3 percent,
calibration is recommended.
To check engine interface accuracy:
Select Fuel Used to be shown as Overlay Data on your unit's main dis-
play. Refer to the Overlay Data segment of this manual for instructions
on how to select Fuel Used data as Overlay Data.
