BOSCH LSU 4.9

The Bosch LSU 4.9 is a planar zirconia wideband lambda (oxygen) sensor, using a dual-cell (Nernst and pump cell) design to measure air-fuel ratio across a wide range, from lambda 0.65 through to open air. It's the industry-standard wideband sensor used across a broad range of aftermarket ECUs and controllers, and can be wired directly to any Emtron KV ECU.
