Fuel Cut Control Unit: Description and Operation

FUEL CUT CONTROL (AT NO LOAD & HIGH ENGINE SPEED)

INPUT/OUTPUT SIGNAL LINE
If the engine speed is above 3,950 rpm with no load (for example, in neutral and engine speed over 3,950 rpm) fuel will be cut off after some time. The exact time when the fuel is cut off varies based on engine speed.

Fuel cut will operate until the engine speed reaches 1,150 rpm, then fuel cut is cancelled.
