6.28 Valve Reponse Value
The parameter specifies the volume to be taken, after a close valves command, before the
fuel flow rate changes. This function is used to determine when the delivery speed should
change i.e. For preset valves, it determines when the normal flow valve closes and fuel
flow rate is switched to low flow.
Note : The default values may differ according to the kernel version.
6.27 Optional Preset Valve
This function allows the use of a low flow valve (reduction valve) in parallel with the
normal flow valve (stop valve) so that during a delivery, both valves are opened. It is
designed to support the use of different preset valve mechanisms.
