Hi all, having just sold both our RS Turbos S1 and fez i have just bought a Focus RS mk1, it has been mapped by turbosmart to stage 1 and has a miltek de cat and full exhaust system. Everything else standard. I have a eml light on, have plugged in getting the fault codes P0420 and P1130. Having checked this out im thinking I have to some how tell the ecu i have not cat, buy an eliminator is it? I have no idea and possibly a new pre cat sensor as that is showing as a fault, it does seem to be running rich and does some times cut out. Normal driveability its fine pulls hard no problems with that just rich at idle and lumpy tick over, will a eml eliminator and a new hego sensor sort this do we think? your ideas and help would be appreciated as i my knowledge is fine if you want a mfi turbo sorting! cheers guys
