3.2.4.2 RPM Limiters and Powershift
This menu can be used to set various speed limiters and PowerShift.
The standard limiters include a soft and a hard limiter. The soft limiter stops ignition partially so
that power is lost. The hard limiter switches off ignition completely.
Under Launch limit an extra limiter can be set, which is activated, for instance, by a button.
Depending on the type of button, NC (normally closed) or NO (normally open), 'Input NC' will have to
be ticked or not. If the NO type is used, do not tick the box. 'Advanced settings' gives the possibility
of setting the ignition moment for several engine speeds at a maximum of 54 degrees after TDC
(retarded ignition is indicated by a negative number). This enables a high boost pressure to be built
up in turbocharged engines without further increasing the engine speed. Should the engine speed
increase in spite of ‘retarded ignition’, the extra limiter will intervene by stopping ignition and
injection.
Warning: When ignition-advance is applied, the temperature of the exhaust gasses may rise so
high that the exhaust valves, exhaust manifold and turbocharger are damaged. We recommend
you do not activate this function for longer than a few seconds!
PowerShift is a function that can be used for changing gear in sequential gearboxes. A switch on
the gearbox enables the engine output to be briefly interrupted, so that a gear change can be made
with the throttle valve fully open. This minimises the duration of gear-changing. The duration of the
interruption can be set to a maximum of 200 milliseconds.
Depending on the type of switch, the 'NC' box should be ticked.
