KMS MD35 manual
Version 4.16 18
3.2.4.1.2 RPM limiters and Power Shift
This menu can be used to set various RPM limiters, powershift and gearposition parameters.
3.2.4.1.2.1 Standard Limiters
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.
For the KMS MD35 management system the maximum rpm
limiter is 20.000 rpm *.
*: with a 60-2 crank trigger pattern the maximum engine
speed is limited to 12.500 rpm.
3.2.4.1.2.2 Launch Limit RPM on button
At launch limit an extra limiter („start line‟) can be set which is activated, for instance, by a button
that connects pin 21 to the ground. 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 (recommended) do
not tick the box. There is also the possibility to set an extra launch limiter which makes it possible
to make the launch limiter variable between these two rpm‟s by connecting a potentiometer signal
to the analog aux2 input or analog aux3 input for the MD35, which can be configured for this
function, see
3.2.4.1.7 Hardware configuration . The potentiometer must have a range between 1kΩ
and 47kΩ. The 5V and ground for the potentiometer can be branched from the 5V and ground sensor
supply. The signal (wiper) of the potentiometer must be connected to one of the analog inputs.
Advanced settings:
'Advanced settings' gives the possibility of setting a fixed
ignition moment (between 54 degrees before and 54 degrees
after TDC. After TDC is indicated by a negative number), fixed
fuel enrichment and fixed PWM boost for several ascending
engine speeds. This enables a high boost pressure to be built up
in turbocharged engines without further increasing the engine
speed. Additional fuel enrichment can be set when launch
control is activated, this is needed to cool the engine. During
activation lambda-control is switched off. Should the engine
speed increase in spite of „ignition retard‟, the startline
limiter will intervene by stopping ignition. The boost pressure
can also be limited during launch by setting the duty-cycle
(PWM-value) of the boost control-solenoid.
The „Delay Box‟ is a special timing parameter for the launch control. The timer is activated when
the launch control button is released. During the countdown of the timer, the launch control
settings are still active meaning that the engine will continue the launch control limit for the entire
duration of the timer. Setting the delay to 0 seconds means that the launch control limit is ended at
the exact moment that the launch control button is released.
„After launch delay‟ will start after the launch control button has been released and the delay box
timer has expired. The after launch delay enables users to set the ignition advance and boost
pressure (duty-cycle/PWM value of the boost control-solenoid) for a certain time period. This means
that engine power is reduced for the entire duration of the delay timer and thus better traction can
be achieved in high power vehicles after launching.
