When installing long tube headers or turbo kits what tables are needed for adjustments of the front oxygen sensors? Currently tuning a 2013 Camaro ZL1 and getting a slow response diagnostic trouble codes. This is HP Tuners software.
This can be a problem with long tube headers as it can reduce the operating temperature of the O2 sensors which in turn affects their output. There's no simple fix unfortunately. The common solutions are to leave the PCM operating in open loop, thus ignoring the O2 sensor output, or you can use a wideband controller/sensor that has the ability to simulate the narrowband sensor output and feed this back to the ECU.
After doing some research their really isn't a set answer. Some tuners have had luck messing with closed loop O2 sensor settings. Going to play with it and see what happens.
