RobPhoboS Posted June 12, 2023 Report Share Posted June 12, 2023 Hey guys, as it's been many, many months since I've delved into the ECU I cannot remember what on earth I might need to adjust slightly to get my idle to come back down to normal when coming to a stop (ie traffic lights). The idle is usually around 800rpm but it'll be around 1200ish unless I prod the throttle lightly, then it'll come back to where it should be. It doesn't happen 100% of the time but more than not, if that makes sense! This is for my DE 350z. Quote Link to comment Share on other sites More sharing options...
AbbeyMS Posted June 12, 2023 Report Share Posted June 12, 2023 really need to see a datalog and a CAL file , I expect it will be due to idle control set up /base idle postions. Quote Link to comment Share on other sites More sharing options...
RobPhoboS Posted June 15, 2023 Author Report Share Posted June 15, 2023 Cheers for that, yeah I went back through an old set up I did, and checked against this one last night. I think it was just Idle Base Position largely, it's not quite there yet but I'll test it again over the weekend. Quote Link to comment Share on other sites More sharing options...
koracing Posted June 17, 2023 Report Share Posted June 17, 2023 Too much idle base or too much dashpot offset usually. Also double check the APS/TPS threshold and make sure you don't have something out of calibration. RobPhoboS 1 Quote Link to comment Share on other sites More sharing options...
AbbeyMS Posted June 19, 2023 Report Share Posted June 19, 2023 G4+ doesnt have dashpot like G4X does far more basic idle set up RobPhoboS 1 Quote Link to comment Share on other sites More sharing options...

RobPhoboS Posted June 20, 2023 Author Report Share Posted June 20, 2023 So far it seemed to be a mix of IBP, and the idle speed lockout, my one was set to 1.2mph for some reason which seems a bit too low. Will test some more in the coming days. Quote Link to comment Share on other sites More sharing options...
