FEATURES
Detonation Elimination Technology (DET)
The DET system prevents damage to the engine from detonation by
going into an engine protection mode whenever the DET system is
active.
When excessive detonation is detected, the check engine light will
illuminate and you may notice decreased engine performance and RPM
when the DET system is activated. In most cases this is temporary and
the operator does not need to take any action. The engine will return to
its normal performance automatically.
If severe detonation occurs, the check engine light will begin to flash
steadily and the gauge indicator will read “dET” (see illustration). The
engine will enter a limp home mode and RPM will be limited to 6500
RPM. The engine will remain in this mode until it is shut down and
restarted.
