    PLX narrow band O2 emulation

    Just ordered the PLX Wideband. Since there is practically no room on my GTO with the stock manifolds and down pipes to add a bung, I want to use the narrowband emulated output of the PLX controller. How do I keep the ECM from setting a code for a failed O2 heater circuit? Thanks

    You have to disable the heater DTC in the tune.
