Delco 808 wideband

Post by Asho88 »

Hi all just wondering which pin the wideband is meant to wire to. Also I want to wire into the old narrow band how does that need to be wired to replicate the narrow band signal for the ECU.

Look in the text file "OSE 12P ECM Pinouts" in the ose 12p zip file for the ECM pinouts including the wideband.

Generally speaking wideband to narrowband emulation has been too slow or inaccurate to work well. That might have changed in 2025 but in general you want to leave the narrowband connected as per factory and install the wideband in to a new bung at the same time.
