NOTE: One must bear in mind that
the purpose of these calibration
screws is to maintain the engine R.P.M.
at it's peak power, a lower or upper
speed will actually result in less vehicle
performance.
The point of maximum power, in the
1988 Formula PLUS, occurs at 8000
R.P.M. while the maximum permissible
engine speed (red line) is 9000 R.P.M.
Adjustment Procedure
To change the calibration screw posi-
tion, back off its locking nut and change
the position of the calibration screw
head. The notch on the screw head
must be aligned with the desired nu-
meral position. See illustration.
, . , CAUTION: Back off the calibra-
T
tion screw locking nut only far
enough to allow a change of position
of the screw head. Never attempt to
remove the locking nut or the calibra-
tion screw. Make sure the adjustment
is set at the same position for all three
(3) screws.
