Summary of change:
Been investigating PID idle control in 1.2.13 Some issues found. Proportional operating when IAC is inactive. Seems like stall prevention, needs it´s own P term for proper calibration '''"IAC close delay"''' (TPS > IAC threshold) overrides all other duty cycle values and is able to shut of the valve completely. Some engines need a minimum airflow otherwise they stumple at low TPS positions and it maybe very difficult to control the pedal at such low loads. * of course setting with the throttle-screw, or providing the necessary leak with some other method would be preferred than always powering (heating) a solenoid from electric power, but powering is also possible * Certainly 255 value would probably solve 99% but still not the proper solution * I vote 0 value be valve never closes and help should explain that. ** so with "IAC close delay"=0, apply the IAC minpwm value even infinite time after the TPS has raised > IAC TPS threshold... right ? That seems to make sense. Isn't it that way already ? In Vemstune someplaces say minmap, other lowmap, needs to be clearer if they are the same or not. Assymetric PID Conf needs explaining. Advance rate of change is a P value not a rate value and therefor needs a new name.
