P015 B & P015D after HP tune?

[SSammy]

I have a 2015 Camaro SS L99/A6. I have the following mods...LT Headers, HF cats, X-pipe, CAI intake, Bo White stage 2 Ported Throttle Body. I ordered an email tune, but after the flash and a few drive cycles, I am still throwing the same codes, Stored and Pending - P015B & P015D, which is both banks, Sensor 1, delayed response lean to rich. The only difference is, after the tune, it hasn't illuminated a CEL. My questions are.....

- Will my systems complete their readiness if this code is there?
- Will this make me fail if no CEL is illuminated, but the codes can be found on a code reader?
- Can this be adjusted/calibrated in HP Tuners, so these codes aren't seen as a mistake/problem and therefore aren't thrown at all?

Any suggestions/help is appreciated.

Has anyone else had this problem?

I'd probably start with who/where sent you the tune.

[SSammy]

You're right. And I am currently, just trying to get some opinions from other members in the meantime.

If you've had a few drive cycles (assuming around 100 miles) and you're still throwing those codes then I would dive into the tune also or even before that, change out your O2 sensors. With your mods the tune calibration isn't that complex. I've had the problem of my car running too lean and burning up my O2's and after a change of sensors and a slight adjustment of the tune I was good to go. Hope I could help

Thank you! I flashed a new tune last night and am starting to go through drive cycles again today. I’m hoping for the best. I also have new upstream o2’s on order. I appreciate it

Any updates?

No codes. I’ve been drive cycling since Friday, over 600 miles, everything has gone to “ready” except the evap and cat monitors. The car runs great on the new tune, it’s a night and day difference compared to stock. Just can’t figure out why these monitors aren’t coming online.

When you say “cycles” do you just mean drives? Or the actual GM prescribed drive cycle? The actual cycle is a pain is the butt. Maybe you haven’t hit all the metrics?

[SSammy]

The actual GM one. Yes it is a major pain and sometimes it seems like it’s going to get me killed haha. I guess that’s possible, but I have followed the procedure to the letter, even researched all the parameters that are required for a “GM cold start” and completed at least 5 cycles that were in the correct temp/ambient to coolant to IAT etc. Definitely difficult to do in Utah temps (less than 39 deg ambient at warm up doesn’t count as a gm cold start). Other than work, this has consumed my week. We’ll see what my weekend brings, this baby may be going completely back to stock soon, well, for a while at least.

Well, I guess you can call that good news. It's running great and you're happy.

[SSammy]

Well, here’s my update....the evap finally reset Sunday night. I was driving to my mom’s house 3 miles away. It happened after a hot start (168 deg at start) and was not not doing a drive cycle (city driving at 25-30 mph stop light to stop light). It took 744 miles and 9 full days. I don’t get GM’s parameters for resetting the evap system, and I don’t think they do either haha, but the car is running great.

Wow, that’s ridiculous. If only there was some way around that.
