So I have been modding my car over the years and recently I went to get a sticker and my car failed even though all my monitors were ready and no CEL were on. I may have had one of the DTC disable options checked. would this cause a fail ?

part 2 of the question... i see there is a patch for the Evo 9 to force inspection pass. https://www.evolutionm.net/forums/ec...us-mrfred.html

Is there such a patch for the evo X/ RA platform ??

 

Yes, do a search on here and you will find the thread.
