Operating Instructions

NOTE

: The first time you switch-ON the

Omnia57 Fuel

Comp

, the fuel pressure gauge will not be enabled, so if

you have the fuel pressure sensor installed, enable it as
explained in the chapter

4.5.2

.

CAUTION:

Each time the fuel computer calculates the

remaining amount of fuel, there will be an error due to the
fact that the K-factor is not mathematically perfect. These
errors, although small, will be added in the same direction
and this will lead after several refueling to have an
increasingly larger error. This error is reset every time you
fill up with fuel, confirming the "FILLED" function. For this
reason it is advisable to fill up when possible to reset the
errors.
