Yeah there are very basic options and I have a stable idle now etc, and I'm sure the more recent ecu's have far better idle control. Just wondered how others had got on.

Just mapped an STi4 with a 2.5 running the GEMS ecu, how have you guys found idle control for both cold and hot ? Really struggled tbh, and it's still not perfect. Shame there's no real idle control ie adjustable idle target speed based on CTS and then ignition and fuel trims to help idle etc. Unles...
