Hello! Have a question, since the installation of the 3″ downpipe I have again and again an error message MIL and namely the error code P0422/ main catalyst efficiency below limit value bank1-freeze frame data:Status injection system bank 1/ closed-normal, status injection system bank 2/ N/A, calculated load/ 12,94%, temperature cooling water/ 89°C, short-term injection trim#1/ 0%, long-term injection trim#1/ -0.78%, speed/2160 rpm, speed / 72km/h Have this tuning pack from MR-Sweden acquired, among other things, the tuning pack included a BSR PPC box, sports air filter, special ignition plug set and 3 inch race exhaust pipe incl. special catalyst, the sports exhaust I ordered directly from Simons from Sweden. The sofware for the downpipe should have been optimized, which I now very strongly suspect has not been made. To be honest, I am very disappointed by this store, because nobody wants to take care of it, nobody replies to the e-mails and telefoni What could you do to make this mistake stop showing up? Because performance doesn’t change. Ask for advice!
