Hi guys,
Having some issues with the Emissions Readiness Monitors actually completing successfully, I have 3 that have been "Pending" for over a week (almost 2) now. I hope it's something simple I overlooked in the tune, I need to get my tabs renewed asap but I want to make sure everything is correct first before I go in for testing.
2008 TrailBlazer SS LS2 E67/T42
CAI w/LS7 MAF, Headers, off-road y-pipe, no rear O2 sensors (have them still) are the major mods.
Tune has LTFTs disabled, STFTs are still enabled. Rear O2s are deleted in the Diagnostics section, Catalyst diagnostic test is disabled along with the Rear O2 diagnostic test.
The pending readiness monitors are CAT (not expecting this one to go to Ready), EVAP, and O2S. I'm confused why these other 2 aren't completing, Ive done numerous cold starts and normal driving including a few GM drive cycles. The O2 Heater test passed just fine, Im scratching my head as to why the O2S test hasnt passed.
I have attached my current rough tune, not close to where I want it, but its' at the point that I dont want to keep flashing tunes in so I dont keep clearing the DTCs/Readiness Monitor status.
Thanks for the help and feedback! I can provide the stock tune as well if needed.
