EVO X Anti-Lag or PBW modes

Post by RickS » Tue Jan 22, 2013 3:09 pm

The ALS system will be enabled if all of the following conditions are met:

· ALS in pin condition satisfied and predefined road speed or throttle position are satisfied.
· Air temperature is < ALS Air max
· Coolant temperature is < ALS Coolant max

If ALS is enabled, the ignition timing is modified by the Pedal Retard factor and a proportion of injection and spark events are disabled by the limiter options. The values for the limiters are obtained from the Pedal Retard, Spark Limit and Fuel limit maps. When the ALS mode is ON then the Pedal Retard Mild, Spark Limit Mild, Fuel Limit Mild maps are usually used.

The Spark Limiter 3D lookup table controls Engine Speed and Pedal limiter, using a reduced range of Pedal just covering the lowest 7 sites of the Pedal Angle table. Output Limiter range is 0% to 99.6%, no cut to almost total cut.

To increase control, tables are used to increase the depth of the limiters when an engine speed is exceeded. For ignition, fuel and retard, the tables used and their operation, download the EVO X ECU manual from our website.

There are 3 basic modes of operation of the anti-lag system. They are:-

ALS Full Active = Off ALS Mild Active = Off
None of the extensive turbo anti-lag features available. Pedal Retard from a calibration map will always be zero. Known as none not to be confused with “N” mode.

ALS Full Active = Off ALS N Active = On
N mode or safe anti-lag mode, if milder settings in “N” mode maps and tables. Pedal retard from a calibration map would, if requested, be taken from the Pedal Retard Mild calibration map.

ALS Full Active = On ALS Mild Active = Off
Full anti-lag mode, only mode for Launch feature to be active. Pedal retard from a calibration map would, if requested, be taken from the Pedal Retard calibration map. If Launch is also active, only possible in this mode, then the highest speed lines rather than the actual speed line are used in the active maps.

Full setup information and descriptions are available in the online manual
