Power Enrich Fuel
Power enrichment tables are used when the VCM detects wide open throttle (WOT) operation and provides extra enrichment to achieve maximum power.

Note: A working, calibrated and correctly positioned wideband O2 sensor is required to tune engine fuel requirements. Excessive lean conditions due to incorrect use of these parameters could lead to severe engine damage.
