Guest rekan Posted November 4, 2013 Share Posted November 4, 2013 96 NA-TT Supra, Stock twins, JDM ECU, FMIC, 3in exhaust with 1 cat, intake. I need something to stop the fuel cut. I have an HKS FCD that made my car really choppy and only allowed intermittent boost. Without t installed, the car is much smoother, though in third and fourth gear, car sometimes jerks a little. Is that a boost leak you think? Next, do I need to go one step colder with the plugs? Thanks! Quote Link to comment Share on other sites More sharing options...
listy Posted November 4, 2013 Share Posted November 4, 2013 Spark plugs - NGK Iridium BKR7EIX Was the FCD set to the right position? If I remember right, it should be set to 9, but someone will correct me if I'm wrong. Quote Link to comment Share on other sites More sharing options...
Guest rekan Posted November 4, 2013 Share Posted November 4, 2013 It was set at 9. So that choppiness could be because of my spark plugs eh? Pretty sure the unit was faulty Quote Link to comment Share on other sites More sharing options...
Homer Posted November 4, 2013 Share Posted November 4, 2013 Is it a JDM or US GTE engine you have installed? I assume from the JDM ECU it's a JDM engine so you just need to have a read here: http://www.mkivsupra.net/vbb/showthread.php?94705-BPU-(Basic-Performance-Upgrade) Quote Link to comment Share on other sites More sharing options...
Guest rekan Posted November 5, 2013 Share Posted November 5, 2013 JDM GTE lol. Who would go out of there way to install a JDM ECU on one? Quote Link to comment Share on other sites More sharing options...
