SpikeyJp_68 Posted May 7, 2018 Share Posted May 7, 2018 As above what cat converter have people used and passed emmisions testing with ? Will be going through an nct so not sure if emmisions differ from mot. Its an n/a shell eith a freshly built 4efte and a tf035 and ill be cutting up a dump pipe and welding it in place. I was thinking a 200 cell would be enough but might get a 400 to be safe ? Opinions welcome as always Quote Link to post Share on other sites
maddox710 Posted May 8, 2018 Share Posted May 8, 2018 If your running it in stock ecu, would of thought 200would be okay for fast idle or whatever they do in test Quote Link to post Share on other sites
SpikeyJp_68 Posted May 8, 2018 Author Share Posted May 8, 2018 Yes im running a stock ecu and stock fuelling for the test. Its at .5 bar stm but will be upping it to .8 bar when i get a wideband. They do a high and low idle measuring CO%, lambda on both and hydrocarbons on high then theyre compared to the limits on their system which differs for each car. A 200 cell is about 70-90gbp plus postage where as a 400 cell is 170-190gbp plus postage Quote Link to post Share on other sites
