I see on guzzidiag 1=idle stepper base , 2=idle stepper break ,3=idle stepper controller.What does this mean? I read that stepper motor depends on temperature engine.Only in start-up stage, the engine control unit signals the stepper motor to let in supplemental air downstream of the throttles. When i turn OFF the main key switch,the connection ecu -guzzidiag is still there for 3 seconds ,the idle stepper break increases and stoped at 176. What are the usual values for these indications(1-2-3) at idle??
