Spartan wideband with mr2link tst185 ecu

Recommended Posts

Black wire to s-gnd, green wire to any of volt4-6. Then configure that ANVolt channel to be lambda1 in the ecu.

connect red & white to switched power (from any relay) & to chassis ground.

Obviously it is not going to work when your cal table is set to KPa and every cell has a zero in it.

For a linear sensor such as a wideband device you should use cal 4, 5 or 6 and set it as below.
