Warning:
When ignition retard is applied, the temperature of the exhaust gasses may
rise so high that the exhaust valves, exhaust manifold and turbocharger will
be damaged. We recommend you to activate this function for no longer than a
few seconds!
Powershift
Powershift is a function that can be used for changing gear in sequential gearboxes.
A switch on the gearbox shifter enables the engine output to be briefly interrupted, so that a gear
change can be made with the throttle valve fully open. This minimizes the duration of gear-change.
The duration of the interruption can be set to a maximum of 200 ms. Depending on the type of switch,
NO (recommended) or NC, the 'NC' box should be ticked. If the
‘use advance settings’ control box is
selected, the
‘advanced settings’ menu must be set.
Advanced settings:
In this menu you can adjust the shift time for
each gear. However, a position sensor must
be present on the transmission housing for
this purpose. In this menu, you can then
specify the ascending output voltages
corresponding to the various gears. This can
be set manually or automatically. The voltage
range is 0 to 5V.
Cut time: Here you can set the desired
injection cut time for each gear(change)
position. The injection will be interrupted for
the time set here.
Delay time: At the moment the Power-shift
switch is activated, it is often desirable to
have a short delay before the switch takes
effect. This is because some resistance is
required to build sufficient power for
sequential shifting (charasteristic of
sequential gearbox).
