APR 2.0 TSI K04 v3.1 Software Now Available!

[tom@aptuning]

Thanks! But even on stock mode, I don't think anybody on 3.1 will throw a visual CEL. I think that's the new norm for APR.

And it only takes me 10 minutes from clearing codes, driving and throwing a P0420. Which kinda worries me that an 02 just isn't working

I updated the post, let me know what you think about it lol

The p0420 doesn't mean your 02's aren't working. Actually they are probably working great if it picks up that fault that quick.

Woohoo, thanks for the advice Tom

No problem, the p0420 is specifically for the cat. In all my years I have never seen an 02 sensor cause that fault.

Then idk, I never got a visual CEL, just a stored code

Either way, my second vibrant spacer came in today so, time for some fun

Good luck. Remember to step down the jetting. I used no insert pre cat and medium jet post cat.

I'm going to go with medium before, small after.

So last night I filled up at a different gas station (name brand, can't remember which) and now I'm quite sure the tune doesn't agree with it too much, anything I can do? I hate octane boosters, but if it'll help..

Hi Guys tomorrow I have a Track day and during a general check I took out my spark plugs (type and gap as recommended by APR). Each of them looked exactly the same, can the experts chime in and comment? Is this healthy?

Mi amigo, Yo creo que esos spark plugs se ven un poco lean. Yo no me preocuparia mucho. Creo que vas a estar bien en la pista.

If you drive long enough in stock mode, the cel will turn on for p0420. Good info, Tom. Much appreciated!

Especially on 3.1. Prior to 3.1, a testpipe file meant that ALL of your files were testpipes.

We changed that with 3.1. Stock mode is exactly that, stock mode. The performance modes disable that code/CEL.

If you drive through at least a few drive cycles (start/stop/10-15 miles) in stock, you will get a CEL. But, long before it throws the CEL, it will ready the test, which is what you need it to do.
