Steve1436215442 Posted October 30, 2014 Report Share Posted October 30, 2014 So I have a 2007 STI with the G4+ EMS installed, got the car tuned pretty well, drives great down the road but the idle control just sucks. Â Warmup is smooth but once the engine is up to operating temperature the idle is very unstable at times (stalling) and will hunt up and down allot at times. I have tried everything with luck. I have the idle control set to OPEN LOOP E-THROTTLE, I have the VE table tuned and maintain about 13.5:1 AFR at idle which is solid. I have tried adjusting the Base Step Idle Table allot, I have it at 1.8 at operating temp which it does the best at otherwise its either too low and dies or it hunts up and down if I put it higher. I'm really stumped here as I come from tuning Hydra EMS which has ROCK SOLID idle control on the STI. Â Any help would be appreciated.

Simon Posted October 31, 2014 Report Share Posted October 31, 2014 Hi Steve if you can post you MAP/PCL file we can take a look. If you turn the idle control to off is the RPM stable when the engine load is constant? Quote Link to comment Share on other sites More sharing options...
