Drive-by-wire idle control utilises the same idle control strategy as PWM idle, making configuration easier.


To use it, once DBW has been properly calibrated, simple set the Idle Drive in the Idle Settings to DBW.


DBW TP Max then states what 0-100% of the idle duty represents in terms of DBW target throttle position. For example, if we find that DBW Idle (to go up to say 2000rpm) requires a DBW throttle Plate position of 8%, then we would set DBW TP Max to 8%.


Then, for example, if we used manual idle mode, and set the manual idle duty to 50%, the DBW throttle plate will set itself to 4%. (50% of the maximum 8% allowed by the DFW TP Max.)


Idle closed loop, and open loop would work in the exact same way as normal idle control, only now, they are driving the DBW throttle plate position from 0-100% of the DBW TP Max. PID would be tuned in the normal way as per the idle control tuning guides.
