The Non Self-Learning EFI-TC1 is great for racers looking for a little help on the gear change, or when a stage of nitrous or boost comes in, or just wanting more consistency and lower Elapsed Times.

The EFI-TC1 is designed specifically to work with the Holley HP and Dominator EFI Systems.

The EFI-TC1 is designed for the budget minded racer who wants the same advanced technology used by top race teams around the world, but does not need all of the advanced features of a Self-Learning unit.
