I wonder how Ko4 tunes will pass now with smog stations also checking the ECU software in socal now.
In the past I’ve passed smog by switching my APR ko4 tune to the stock boost levels and emissions readiness while using spacers in my high flow downpipe.
However looking at the APR website it’s only the stage 1 ko3 tune that has a carb number. Doesn’t mention if their KO4 tune at stock boost levels will identify on the Smog computer as their stage 1 KO3 tune.
Thinking further about it, even if the tune registers on the smog computer as a stage 1 ko4 tune, that carb number will likely only match Golf R’s so it still won’t pass.
Maybe it’s time to just give up the Ko4 and reinstall my stock KO3 turbo and just swap between Stage 1 and Stage 2
Quick reboot for this thread. I have smog coming up. From what I recall reading, cali smog now test for approved tunes. Anyone this year do a smog with a stratified tune with emissions on? Or am I basically forced to tune to stage 0 or unmarry the AP before smog? Currently im green on all readiness, but I am tuned. I'd love to drive right into a smog station, but I want to see if anyones rolled into one and still had a tune. Thanks!

Guess you will find out soon enough. Just go to the shop with free retest?
Personally I doubt that the new system (which is about one year old at this point) and ECU software DB it uses is super accurate and reliable.
Last time I went in for the APR tune update it was $100 or $150 for labor. NorCal.
I also have the 034motorsports cable which can (theoretically) flash my ECU back to stock or their tune.
But of course not back to APR 1+ I'm currently on.
Yeah, mine is not K04 but I don't think it matters much for this discussion.

The Cobb base tune is CARB (EO: D-660-37) approved Get the sticker they sent me mine. At least you would appear to be legit even with stratified
They still don't know if it's tuned IMHO my MK5 no problems on unironic stage 1 unless the dude at a test only didn't care which I doubt. Smog'd it recently maybe 3 months. If it passes readiness, I think all is still good.
