mr2slow Posted June 19, 2016 Report Share Posted June 19, 2016 hello everyone , i am the proud new owner of a G4+ plugin ECU on my 91 mr2 turbo. I noticed my idle is very rich. it stays this way even after warm up. my lambda target is set to .95 but the actual never leaves .67. Anyone have any tips on how to lower this. would i adjust my fuel table by trying -5 across the table? or is there a better way. i just want to clear up my idle so my neighbors stop complaining. i plan on getting it tuned by a reputable dealer here in the states. just want to drive it around the block and get it to idle better. Thanks for the help! Quote Link to comment Share on other sites More sharing options...
