16.12 Driver Box (DB3) Staging Signal Function
This function is similar to the previous Staging Signal, except that the signal is inverted so
that it is compatible with the Haltech DB3 Driver Box, used for controlling extra injectors.
There are no programmable parameters associated with this function.
16.13 Turbo Timer (TT)
The Turbo Timer allows the engine to stay running after the ignition key has been removed to
maintain oil and water supply to both the engine and turbo to allow them to cool at idel speed
until certain conditions are met. This will help prevent acceleration of wear to both engine
and turbo due to the high operating temperatures such engines are subjected to.
Care should be taken to make sure the relays are wired correctly, and that an over-ride switch
has been fitted to allow the engine to be switched off manually while the turbo timer is active.
See figure 16.13 for the correct way to wire this output. The ECU detects if the ignition
switch has been turned off via the Auxiliary Input. (The Auxiliary Input Function must be
selected as Turbo Timer in the Input/Output page.
There are three programmable parameters:
Air Temp (°C)
If the Air Temp falls below this value after the ignition key has been removed the
engine will be switched off regardless of all other parameters.
Coolant Temp (°C)
If the Coolant Temp falls below this value after the ignition key has been removed the
engine will be switched off regardless of all other parameters.
Run Time (mins.)
This is the maximum time that the engine will run after the ignition key has been
removed regardless of all other parameters. This value can be set to the nearest half
minute.
