Help pls, FBO E92 335is throwing code H30F1 on Cobb Accessport

alex-e92 · 12-08-2016, 10:05 AM

Hey guys, yesterday I got a code on my Accessport V3 that has to do with knock in cylinder 1 due to wrong boost levels. I am currently catless, and running the Stage 2 + Sport tune. I called Cobb and they said their tunes do not support catless dp's and recommended me to go and get a custom tune. I did read up on the dp fix for catless cars (which I'm going to have to buy anyway to pass emissions) so will the dp fix help me with my tuning problems, or do I really need to get a custom tune? Thanks.

Get the map that automatically deletes or hides the code for catless, I think it may be the

stage2aggressive map. That is what I am currently on with catless and I have had no codes since my downpipes were installed.

What I would recommend is always use a custom tune. Every car has their differences.

You only have the dp fix to get the emissions testing done

how old are the plugs and coils?
