well looks like my 2017 v4.02 stage 2+ finally got the CEL for the rear o2 sensor. Looks like a v4.03 was just uploaded I hope this issue was addressed.

Your calid K00C? Let me know if the V4.03 is actually any different.

Edit: shiv says there will be no difference. Just added the K00D (2017 auto) calid.

What code did you get? What issue do you think he needs to be aware of?

from that page

"Code P2270 is an indication that the O2 sensor does not detect the catalyst efficiency and can cause the vehicle to fail an emission test."


I cleared it for now I will see if it pops back up again

P0420 is the typical cat efficiency code. That's the one that is normally disabled in a tune.

cold start adjusted the initial timing and lowered the rev per temperature

I remember people toying with removing the cold start and getting camshaft and crank sensor codes. The timing adjusted is cam timing.

Anybody gotten a P0016 code on the v2.076 E85 tune? I used that tune a long time and only started getting it about a month ago. Even after clearing the code with the OFT it always comes back pretty soon after. I recently flashed to the v4.01 tune which made the P0016 go away completely. So, now I'm wondering if there's something actually wrong with my camshaft or if it was just tune related? My car runs great and I haven't noticed anything weird while driving, so I'm hoping it's just something with the older tune.

Not sure if it’s related but since I flashed v4.03 Stage2+ I noticed tech goes up to 2k and the car shooks a little like rough idling for one split second after I shift into gear after warmed up the car. After that split second all comes back down to normal. I always warm up the car in the morning for a good minute or two until tech goes down to around or below 1k before shift into gear.

car has a little "dip" of idle when it finishes the cold start and switch the ignition timing from 0 (set by v4 tunes) to the normal timing of about 10
there is also a dip when the VVT activates, not something to worry about

It wasn’t really a “dip”, the car was idling around 1k rpm after I finished warming up the car, but when I shift into gear the tech would spike up to 2k rpm for a split second while the car shooks a little then all go back down to normal after that quick split second.
