finbro ecu stock o2

  1. Finbro ECU with Wideband o2 question

    Grom Performance
    So I ordered the finbro ecu from hard racing for my 18 grom that has an hindle exhaust and soon to install chimera intake and tb cam. My question is if i want to run an aftermarket wideband o2 gauge and sensor how would I go about doing that? Brand ? preference? Can I piggyback the o2 sensor...
