Does anyone know if there is a bug with the idle speed setting table on a 2006 5.9? I am trying to lower my idle speed from the stock 750 to somewhere closer to 625. I adjusted the minimum setpoint, the baro and the ect table and it still idles at 750.
Does rescaling the table work? Does the ECM "see" the scale and go off of it? The stock scale is weird, jumping from 68 degrees to 220 degrees. At first I adjusted the scaling of the ect table, but when my idle speed didn't change i put it back to the stock scale and set the idle to be 625 between 60 and 220.
Thanks for any help!
