Smarty Touch Settings for TNT-R Software (2003-2007)
This article details the Smarty Touch power level and adjustable options for the TNT-R software.
WARNING: THIS SOFTWARE IS DANGEROUS TO A STOCK VEHICLE
Aftermarket, turbo, injectors, lift pump, injection pump, and a built automatic transmission AT LEAST are required!
You have access to the following power levels with the TNT-R:
Level 1: 130 horsepower with timing
Level 2: 160 horsepower, no timing added
Level 3: 160 horsepower with timing
Level 4: 190 horsepower, no timing added
Level 5: 190 horsepower with timing
Level 6: 230 horsepower, no timing added
Level 7: 230 horsepower with timing
Level 8: 260 horsepower, no timing added
Level 9: 260 horsepower with timing
You can often get more horsepower than advertised, depending on modifications. We have seen upwards of 400+ horsepower gained from the tuning alone.
We only recommend running with no timing if you are stacking with another tuner that also adds timing.
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.
The RPM option will allow the truck to make up to 4000 RPM. This is either an on, or off setting. Keep in mind that the truck needs to have the motor sufficiently built for this purpose.
The shift limiter will eliminate the de-fueling between shifting with automatic transmissions. We do not recommend using this setting unless the transmission is built to handle the added stress. This will take away the shift indicator lights (park, neutral, drive etc) while the limiter is removed. This is to let you know it is functioning properly.
