Smarty Touch Settings Dodge Cummins 2003-2007 Common Rail
This article covers the Smarty Touch settings for the 2003-2007 Dodge Cummins trucks. This does not cover the TNT-R software, click <here> for information about that software.
Level 1: 30 horsepower with timing
Level 2: Same as 3, but with no timing
Level 3: 60 horsepower with timing
Level 4: Same as 5, but with no timing
Level 5: 90 horsepower with timing
Level 6: Same as 7, but with no timing
Level 7: 160 horsepower with timing
Level 8: Same as 9, but with no timing
Level 9: 210 horsepower with timing
These values were all calculated on a completely stock truck on the chassis dynamometer. With supporting modifications, the horsepower values can be higher than advertised. The added torque is about double the horsepower generally.
The only reason to run with no added timing is if you are stacking multiple tuners. We generally don't recommend this, but if you do make sure to stay on the even-numbered settings. Otherwise, use the odd-numbered settings for best results.
The Smarty Touch also has adjustable settings for this year range. The options to choose from are as follows:
Timing controls how soon the injectors open to spray fuel. When turning this up, you will typically see less smoke, less exhaust gas temperatures, and better fuel economy. On this setting, 1 is the most aggressive timing, and 3 is the least aside from stock.
The Torque Management is a system put in place by Dodge to help save wear on the drive-train. The more you turn this setting up, the more bottom end torque you will see. This is also quite a bit harder on the transmission, so it is worth noting that you will want to be careful if the transmission is stock. This is a setting that is 1-3, 1 being least aggressive and 3 being most.
Rail pressure controls the mapping for the pressure in the fuel rail of the truck. We don't raise overall rail pressure on the regular software, but we do increase how fast it ramps to the max value per Dodge, and how long it stays at that value. This is because prolonged use of increased pressure can cause damage to Common Rail injectors. This setting is also 1-3, 1 being least aggressive and 3 being most.
The wastegate setting is used when you have an aftermarket turbocharger. When set to stock, the wastegate will open at the factory defined value. This is at about 32 lbs of pressure on the 2004.5-2007 trucks if they are relatively stock. The 2003-2004 trucks do not have this setting on the Smarty as the wastegate is mechanically actuated
The speed limiter sets what the top end miles per hour is limited to. From the factory, this is around 105 MPH. This setting ranges from 25-250 MPH.
For first time tuning with the Smarty Touch, we recommend setting these all to 1 (with the wastegate on or off depending on if you have an aftermarket turbo). Most people don't need to adjust the speed limiter, but be sure the truck is equipped to handle that kind of speed and that you aren't breaking laws when doing so.
Run your preferred power level with the settings above for around a week or two so that you have a good feeling what the tuning is capable of. You can always re-adjust from there to dial in to your needs.
