16.17 Engine Control Relay
This feature allows the 12 volt supply to the engine to be disconnected when the ECU is not
powered up. There are no parameters for this feature. The engine control relay should be
wired as shown in figure 16.17. The ECU is not capable of supplying power to the relay or
the components it drives but can sink the current required to energise the primary winding of
the relay.

16.18 VTECH
This feature allows the operation of the variable valve timing associated with some modern
engines. This feature acts purely to control a switching solenoid and is not capable of
controlling continuously variable valve timing.
On RPM
This field defines the engine speed above which the VTECH is enabled. This field
must be greater than Off RPM or it will be ignored.
Off RPM
This field defines the engine speed below which the VTECH is disabled. This field
must be less than Off RPM or it will define both the switch on and switch off RPM
forcing the ECU to ignore On RPM.
On Load Bar
This field defines the engine speed above which the VTECH is enabled. This field
must be greater than Off Load Bar or it will be ignored.
Off Load Bar
This field defines the engine load below which the VTECH is disabled. This field
must be less than Off Load Bar or it will define both the switch on and switch off
Load forcing the ECU to ignore On Load Bar.
