Unlike current narrow band air/fuel ratio systems, Dynojets Wide Band Commander module uses a Bosch 5-wire LSU 4 wide band sensor that can read ratios from 10.0:1 to 18.0:1
When installed, the Wide Band Commander provides a 21/16 black- or white-faced 270° sweep electric air/fuel ratio gauge with programmable warning light and mounting hardware, plus data recording that can be retrieved and analyzed with the supplied software package
