Post by: Dan_GTi8v on 24 May 2011, 12:38: n112 is stuff to do with the secondary air injection, which basically heats the cat up faster so it gets to operating temperature more quickly. I removed all the SAI related stuff when removing n249 to tidy up the engine and give me more room. Apparently it only makes a difference in the first 15-20 secs of engine running anyway
