The TMS-Drag-Lite is our most affordable Self-Learning Traction Control system. By monitoring the average rate of acceleration of the drive shaft, and reacting to any sudden increases in that rate.  the TMS-Drag-Lite will automatically adjust to changing conditions, keeping the internal settings at optimal levels.  The user can adjust the overall sensitivity of unit to achieve the desired results.

The TMS-Drag-Lite is designed for the budget minded racer who wants the same advanced Self-Learning technology used by top race teams around the world, but does not need all of the advanced tuning features of a TMS-Drag-Pro.

The TMS-Drag-Lite is compatible with most drag racing ignitions systems and timing accessories in use today. It is also compatible with the new AMS-2000 boost controllers,  as well as a special version built specifically to work with the Nitrous Express Maximizer 3 Progressive Nitrous Controller.

These units are perfect for racers looking for the unmatched precision of our Self-Learning units to get more aggressive with their tune ups, or just a little help on the gear change, or when a stage of nitrous or boost comes in.

The TMS-Drag-Lite is a great way to get the advantages of a Self-Learning unit, without having to buy the top of the line TMS-Drag-Pro-2 unit. 

The TMS-Drag-Lite unit can be upgraded to at any time to the more advanced TMS-Drag-Pro-2 units for the price difference.

Self-Learning units like the TMS-Drag-Lite or TMS-Drag-Pro automatically adjust to the continually changing conditions as you go down the track.
