C5 rs6 upper o2 delete
Posted: Thu Nov 17, 2016 1:21 pm
Just wondering how difficult it would be to code out the upper lambdas myself ? . I gutted the precats whilst the engine was out and now I get a rather annoying EML light every few days . So what's involved and what kind of hardware/ software and ability level would I need to be able to do it myself ? .
