3.2.4.1.10.4.3 Boost reduction to gear position
The system has the feature to reduce boost pressure at each separate gear (only possible if the
gearbox is calibrated in the system). The values which can be set here are correction percentages
on the actual used PWM-map.
3.2.4.1.11 A.L.S.
A.L.S. (Anti Lag System): This feature can be used in order
to maintain boost pressure (only with turbocharged
engines) during ‘closed throttle’ situations to eliminate
turbo lag. With the help of an electronic air-valve which
can make a bypass around the throttle body, the
turbocharger can keep on pumping air into the engine.
To prevent the engine from over-revving the ignition can be
retarded here at the different rpm levels. For cooling of
the engine extra fuel can be added. To limit the boost
pressure also a fixed PWM value can be set. The fuel
enrichment and PWM boost are both percentages.
If using variable A.L.S. by connecting a potentiometer
signal you can vary the PWM value from 0 to the value set
here in the A.L.S. settings. The potentiometer must be in
the range of 1 kΩ - 47 kΩ. The variable signal from the
potentiometer must be connected analog aux input on pin 4. The 5V for the potentiometer can be
branched from the 5V sensor supply on pin 14. The remaining pin of the potentiometer must be
connected to the ground on pin 17.
Warning:
When using the A.L.S. be aware of extreme wear and shortage of lifespan of
the turbo, exhaust-valves, exhaust manifold etc.
