Fuel Injection Timing Correction Amount
The difference A between the top dead center mark (1) and the
crank position sensor top dead center detection position mark (2) is
the correction amount for fuel injection timing.
Calculate the correction value referencing the following and
using a diagnostics tool, overwrite the injection timing correction
amount in the "data overwrite/confirmation".
(Remarks)
• 1 mm = 360 ° / (Flywheel Diameter × π)
(For example)
FD = 300 mm → 1 mm = 0.38 °
Correction amount (CA) = 0.38 × A (mm)
• If the crank position sensor top dead center detection position is
in front of top dead center, enter a negative value.
• If the crank position sensor top dead center detection position is
in back of top dead center, enter a positive value.
