3.2.4.1.17 Traction control settings
To enable the traction control you have to enable the box
in front of the „Activate traction control‟. Traction
control is only possible if the KMS speed sensor -> CAN
converter 4-channel is used! Users can put a switch in the
12V supply of the speed sensors or KMS speed sensor ->
CAN converter, to enable them to switch the traction
control on and off.
Users can also define at which speed the traction control
should activate.
3.2.4.1.17.1 Activation window
In the Activation window, users can define the parameters for the traction control. The „start at
speed difference‟ determines at which percentage of speed difference between front and rear, the
traction control will activate. „Initial retard‟ is the initial ignition retard which is used by the
traction control when the speed difference between front and rear exceeds the set value („start at
speed difference‟).
„End at speed difference‟ determines the maximum percentage of speed difference between front
and rear, where the traction control ends. The „maximum retard‟ is the maximum ignition retard
for the traction control. If the speed difference increases
above the set „end at speed difference‟ value, the
traction control will stay active using the maximum
ignition retard.
For example when the traction control starts at a speed
difference percentage of 10% (front speed sensors at 100
km/h and rear speed sensors at 110 km/h = 10%
difference in speed) and ends with a speed difference
percentage of 40% (front speed sensors at 100 km/h and
rear speed sensors at 140 km/h = 40% difference in
speed), with an initial retard of 5 deg and maximum
retard of 20 deg, the traction control is set to the
ignition retard and speed in the graph on the right.
3.2.4.1.17.2 Ignition reductions
Before the traction control intervenes, it‟s possible to reduce power(ignition) for better traction.
This can be done for the different gearpositions or speeds. If a value or box is set to 0, it won‟t be
taken into effect.
Activate reduction
The ignition reductions should become active at the moment that the engine starts to make too
much power (high boost/throttle position) and the vehicle looses traction. If the ignition reductions
start too early (at low boost or throttle position), the reductions can intervene with the idle control
or you can loose „bottom end‟ power. Therefore you can determine which throttle position (TPS)
and boost pressure (kpa) the ignition reductions should become active.
Ignition reduction to speed
Users can determine the amount of ignition retard for multiple speed intervals. The first row
contains ten boxes where speeds can be entered, the first box is fixed at 0. Corresponding to each
speed intervals (sections between the ten speed boxes in the first row), the retard of the ignition
can be set in the second row.
