Main Features

The main features of the Smarty S-06 are as follows:

CaTCHER Software

The CaTCHER software by Smarty is what makes it stand out from other diesel tuners and programmers. This makes the device super-efficient, as it provides power, even when your vehicle is stationary. This way, you can experience the power increase at wide-open throttle and throughout the entire RPM range.

Fastest Download Speed

This programmer has the fastest ECM update download speed out of all the brands available on the market. It takes only 3.5 to a full five minutes each time it updates. Even the closest competition is three times slower. It also updates the ABS tire height in just a few seconds and reads diagnostic codes in plain text. On top of all that, the updates for the software itself are completely free.

Speed, RPM, and Shift Limiting

Smarty can program limits when it comes to speed, RPM, and shift settings. The speed limiter can be adjusted anywhere from 25 to 250 MPH in intervals of one mph.

The RPM and shift limits are only available in the race software. The RPM limiter can be programmed at stock or high. The high setting allows the engine to reach nearly 4000 RPM.

The shift limiter can be programmed as on or off. If it is off, the engine can be at full power even during gear transitions or power breaking.

Power and Performance Levels

The Power on Demand feature allows users to go from zero to 100 on the power scale no matter their default setting. Also, it has ten different performance levels. These are the standard REVO power levels, and they work as follows:

  • SW no. 0: Half Power

  • SW no. 1: 30 Horsepower increase with additional timing

  • SW no. 2: 60 Horsepower increase with no additional timing

  • SW no. 3: 60 Horsepower increase with additional timing

  • SW no. 4: 90 Horsepower increase with no additional timing

  • SW no. 5: 90 Horsepower increase with additional timing

  • SW no. 6: 160 Horsepower increase with no additional timing

  • SW no. 7: 160 Horsepower increase with additional timing

  • SW no. 8: 210 Horsepower increase with no additional timing

  • SW no. 9: 210 Horsepower increase with additional timing


The positive aspects of this device are listed below. Take a look to decide whether you want to invest in it.

Fuel Saving

This device is capable of saving fuel and, in turn, saving your fuel costs. It is highly efficient as it doesn’t only perform powerfully when the engine is in full throttle, but also when it sits idle. It also has great downloading speed when it comes to updates. All these things make it energy and time-efficient.

Easily Programmable

It is super easy to work with and does not require any tools or fuses. It is easy to program and adjust in accordance with your truck's speed. All you need to do is take the cord of the device and attach it to the OBD-II port located below the dashboard. Then follow the instructions shown on the screen. In just a few minutes, the process will be done.

Great Performance

The overall performance of this programmer makes almost every other competition on the market seem quite lackluster. Even its downloading speed is better, with the ECM updates downloading at a rate of 3.5 to five minutes. Similarly, the ABS updates are downloaded at incredible speeds.

Different Power Levels

Smarty S-06 comes with ten different levels of power for its users. It is highly efficient and effective in saving the truck's power usage and the driver's time. The power levels range from zero to 210+ mph, which is quite impressive. Also, the optional TNT-R programming is for people who want increased horsepower for modified trucks.


The negative aspects of the product are:

Low Temperatures

It is recommended by the company itself that you do not store their device in your truck if the temperatures become lower than 32°F. This is because the cold temperatures may cause the device to gather moisture inside. This can lead to problems in proper functioning or cause damage to it.

Limited Warranty

This device is a tough competition to other products on the market. But no matter how durable or efficient a product may be, there may still be circumstances in which it can get damaged. The good news is that the company does offer a warranty. The bad news is that it is a limited warranty of only one year and comes with some conditions.
