Description

It provides control via CAN bus and is compatible with leading aftermarket ECUs. This kit uses a Bosch LSU 4.9 sensor to measure oxygen in exhaust gases, enabling on-the-fly ECU adjustments. Its fully digital nature eliminates signal loss, delays, and errors common with analog alternatives, and it never requires free air calibration.
