Idle Control Not Functioning( AIM Error 0 )

[PWCGUY]

I have an M400 with DBW and have not been able to get the idle control working. I have setup the Idle control and the idle aim RPM table, see below. After looking around in ECU manager I have found that the AIM RPM and Aim Error are 0 while the motor is idling so that is why the idle control is not working. I have checked the TPd and TP positions and they are well below 10%, ground speed is 0 and idle speed is 1000 - 2400 RPM. Idle Aim RPM Comp is 0, Idle Min output table is set to -100, Idle Max output table set to 200, Idle min Integration limit table set to -10, idle max integration limit table set to 30, Idle Initial Position -200, Idle normal position 0, Idle fuel and ignition comp 0.

Is there some other setting I'm missing to get this to work ?

Any input is appreciated.

Thanks

Well I answered my own question. The problem was the the DBW Aux2 funtion number needed to be set to 6 so that idle control is enabled. Now I'm having fun with tuning of PID parameters.

There is a document here in the first post which may be helpful to you on the PID tuning..... Helped me (which wouldn't be hard!)
