FiTech Launches Cable-Free LS Drive-By-Wire Systems

Swapping an LS into a vintage ride is great until you have to figure out the throttle linkage. It is always a hassle to get the geometry right without it binding or looking like a mess under the hood. FiTech Fuel Injection is aiming to delete that headache for good with their new drive-by-wire systems. The company just rolled out this setup for builders who want the sharp response of a modern engine without fighting with archaic mechanical cables.

The centerpiece here is a massive 102 mm throttle body. Usually, running an intake opening that big makes a street car touchy and hard to drive at low speeds. FiTech solved that by integrating advanced electronic controls and preset drive modes directly into the ECU. The system adjusts the pedal feel depending on what the vehicle is doing, whether it is towing a trailer or sitting in the staging lanes. It smooths out the inputs so the driver gets clean, linear acceleration instead of a jerky ride that snaps their neck.

For someone wrenching in the garage, the real win is the installation. There are no brackets to fabricate and no cables to route through the firewall. The new drive-by-wire system from FiTech comes with the ECU, the harness, sensors, and the controller all in the box to streamline the conversion. One interesting detail is that FiTech intentionally left the pedal assembly out of the kit. That sounds like a missing part, but it is actually a purposeful move; it lets the builder pick a pedal that actually fits the specific chassis rather than trying to force a generic plastic pedal into a classic muscle car floorboard.

FiTech is backing the hardware with a three-year limited warranty, which is a nice safety net for anyone nervous about switching to full electronics. It is a solid way to clean up an engine bay and get the car driving like a modern vehicle. With these new drive-by-wire systems now available, the days of dealing with sticky cables and rusty return springs are officially numbered.
