Vtec - ECU Master EMU User Manual

VTEC

VTEC control parameters are used for controlling variable timing and lift of the valves using on/off
type solenoid. There is an option to automatic switch tables when the solenoid state changes. To
do this in parameters Tables Switch/Table switch mode option VTEC Switch must be enabled.
Activation of VTEC control solenoid can be defined by two non-continuous areas, in ranges of
RPM, TPS and intake manifold pressure (MAP).
