Electronic Fuel Computer Adjustment
The engine electrical fuel computer (Figure 6-1) must be
adjusted to the Engine Log Book recommended specific gravity
position for the type of fuel. If no entry in the Engine Log Book,
ensure the following settings are observed.
Jet A, Jet A-1, JP-5, JP-8 . . . . . . . . . . . . . . . . . . POSITION 5
Jet B, JP-4 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . POSITION 6
50% or more Aviation Gasoline . . . . . . . . . . . . . POSITION 7
The fuel density adjustment selector has 11 positions num-
bered clockwise from lower left side of the dial. The knob
may be rotated one click either direction from the recom-
mended positions to compensate for individual engine char-
acteristics or installation effects.
WARNING: Engine surge may occur if the recommended
specific gravity adjustment is not adhered to. If surge
encountered, refer to engine maintenance manual.
CAUTION: Clockwise trim (corresponding to a decrease in
specific gravity setting) on the fuel computer without a
change in fuel specific gravity results in higher turbine tem-
peratures during start, acceleration, and deceleration.
