HPTuners has listened to your feedback and have released the first major update to the 2003-2007 Dodge Ram 5.9L Cummins since our first to market release in December. This update includes 400 new tables, scalars and switches. Notable highlights include:
- Renaming and significant reorganization of existing parameters.
- Diesel fueling is now broken out into its own tab to allow for better organization of individual parameters.
- Parameters have been moved and regrouped according to injection event, purpose and cosmetic layout in VCM Suite.
- Added high idle feature switch with adjustments. Minimum, maximum and increment RPM are fully adjustable. When activated and the set button is pressed at idle, each time the cruise Accel or Decel buttons are pressed, the RPM will raise or lower by the increment amount to the min or max.
- Added 2005 model year O/D off feature. When enabled, on the O/D off button will actually turn off overdrive instead of actuating tow/haul mode. This works in conjunction with the latest OS which is already included with HPTuners.
