the als system ,when armed will not actually do anything until the ecu see's over 5% throttle opening then the system is active for as long as the throttle is sat closed, after a period of 10 secs if the ecu sees no throttle movement the als retard is reverted back to normal timing strategy, having a system that is 'just switched on' may cause you alot of problems with over revving the motor.

my als on stage one with no retard ( i.e valve one fully open) will give the engine approx 4500rpm with the trottle plate shut, with stage two active and no retard the engine sits on the limiter with the throttle plate closed thats how much air we flow for als
