Sensor Cable 18ft LSU4.9

The Sensor Cable 18ft LSU4.9 by Innovate Motorsports is a precision data transfer cable engineered to connect your LM-2 air-fuel ratio meter directly to a Bosch LSU 4.9 oxygen sensor. Built for serious tuners, engine builders, and performance diagnosticians, this 18-foot cable bridges the gap between real-time combustion monitoring and your logging or display equipment. Whether you're dialing in a carbureted street engine, tuning a forced-induction platform, or validating closed-loop fueling on a custom ECU, this sensor extension enables remote sensor placement without sacrificing signal integrity over distance.

The 18-foot length eliminates the need for intermediate splitters or signal boosters, allowing you to mount your wideband sensor in the exhaust manifold or downpipe while keeping the LM-2 display and logger inside the cabin or mounted safely on the dashboard. Innovate Motorsports engineered this cable to maintain signal fidelity across its full run, critical because even minor EMI interference or voltage drop can produce false AFR readings that corrupt your tuning data. The shielded construction protects against noise from ignition systems, alternators, and engine control harnesses—a real concern in tight engine bays with dense wiring. At just 1 lb, the cable is lightweight enough for permanent installation without adding parasitic weight or requiring additional support brackets.

This cable is essential for any build running a Bosch LSU 4.9 wideband sensor with Innovate Motorsports data acquisition or display equipment. It's particularly valuable in turbo and supercharged applications where tuning precision determines the difference between peak power and catastrophic detonation. The 18-foot span accommodates virtually any engine compartment layout—from compact inline fours to big-block V8s—without compromising sensor responsiveness or forcing awkward sensor placement. Installation is straightforward: connect the LSU 4.9 sensor connector at the exhaust end and plug the LM-2 connector into your meter or datalogging interface. For serious dyno sessions, road racing, or street tuning where wideband feedback is non-negotiable, this extension cable is the proven standard.
