Hello guys, always getting some good answers here so I知 gonna ask away. I知 currently running nameless long tube headers with oft stg 2+ 93 octane tune. Few days ago I致e had p0030 popped up, I believe it痴 my o2 sensor. I had the CEL for days and it went away by itself.. and now I知 just diagnosing everything and I noticed that my tablet shows KC learning number which is keep going up (anywhere from 0-6.00) during acceleration and sometimes I see anywhere from 0-2.00 briefly on knock corr column during acceleration. If anyone knows any of these symptoms it would mean a lot.
