P015b and P015D codes after long tube headers
So recently I got stainless works 1 7/8'' long tube headers with high-flow cats installed on my 14 camaro ss. I also got an SCT x4 tuner with it and I'm currently using the preloaded tune. A couple of days after I got the headers installed my check engine light came on and P015b and P015D codes popped up. What exactly does this mean because I've read different answers for why this pops up? Thanks

Preloaded tune is probably not set up to support headers. Get a custom tune. Those are slow response oxygen sensor codes. Your O2s have likely been moved further downstream which means it takes the exhaust longer to reach it, must be calibrated for in the tune.

If u got codes, ur sctx4 should tell u what each mean when u get the programmer to read for codes, highlight each code and click mid button and a definition of what the code means will show...if u have custom tune, your tune will need to be updated....if u purchased support from dynosteve then he can send u a custom tune for it that will fix those codes

Delayed response from the o2s being further downstream has to have the code disabled in the tune, not just the rear o2s being disabled.

Weird...... When I had my 1st Camaro and used the X4, it had the option of headers and no rear O2s. Never had any issue?

I know SCT and others were forced to start removing some features by the EPA in handheld updates. Hope that hasn't started already. I thought it was the diesels they were really after.
