The EFI-TC1 is our entry level Traction Control system For Holley EFI Systems.  This Non Self-Learning system monitors the drive shaft speed and reacts to any sudden increase in that speed.
The user can adjust the threshold of over acceleration that will cause a correction (AFR).  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, Dominator & Terminator 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.  The EFI-TC1 is a great way to started with traction control without having to buy a more expensive  Self-Learning EFI-TC2 unit.  The EFI-TC1 unit can be upgraded to at any time to the more advanced unit for the price difference Self-Learning  units like the EFI-TC2 automatically adjust to the continually changing conditions as you go down the track.
