LR3/Disco 3
The TdV6 implementation of throttle progression is based on a fixed blend time. The torque will blend from that on one
map to that on the new map (for the same pedal position) over a fixed time. This means blending will always take the
same amount of time but when the torque change is small the torque increase over time will be small, whilst if the torque
change is greater then the torque increase over time will be steeper. The resulting acceleration of the vehicle will depend
on the torque difference between the two maps as well as on the gear and range selected. The worst case blending that
could ever occur has been calibrated to match the blend rate for petrol derivatives as closely as possible, so as to give a
transparent behaviour to customers. For additional information, refer to

CENTRAL JUNCTION BOX
The ECM is connected to ignition switch I and II. When the ignition is turned on 12V is applied to the Ignition Sense input.
The ECM then starts its power up routines and turns on the ECM main relay; the main power to the ECM and it's
associated system components. When the ignition is turned OFF the ECM will maintain its powered up state for up to 20
minutes while it initiates its power down routine and on completion will turn off the ECM main relay. The ECM will normally
power down in approximately 60 seconds, do not disconcert the battery until the ECM is completely powered down.
