I'm a new Dodge-Cummins owner and recent subscriber to the TDR (impressed with both). I remember reading somewhere recently about an accessory, possibly aftermarket, that would allow the driver to raise the idle speed on the Cummins ISB to approximately 1100 rpm to allow leaving it idling for longer periods while avoiding unburned fuel and crankcase oil dilution. Do any of you have knowledge and/or opinions of such an accessory? Can anyone point me to a source I can buy one from? Your opinions, advice, and information will be appreciated.
