[QUOTE="decipha, post: 15682243, member: 74327"] first off, SCT is ancient for tuning any EEC, 10 years ago moates came out with a realtime emulator for the eec-iv and eec-v that basically turns your eec into an aftermarket standalone with realtime tuning and far superior datalogging go to moates.net and get yourself a quarterhorse, you will thank me later the reason why the idle is kicking up when the iac is plugged back in is cuz the duty cycle is so high at a warm stable idle you want the isc duty cycle below 35%, ideally 10% is perfect which is basically off set the throttle body airflow scalar to 0, set the isckam update rate to 255 to disable it, then be sure to clear the KAMs go to the fn875 idle air neutral function and set the entire y axis to 1.0, you can 0 out all the rpm values other than the top value of 16384 but not neccessary go to your isc multiplier table fn1862 and adjust those values to get IPSIBR to stay as close to 0.000 as you can get it from cold start to warm idle logging with SCT and doing the log, adjust, save, upload to handheld, flash to ecu method, then re-log and adjust again just to repeat the process takes several hours, with the quarterhorse you can dial it in 10 minutes making realtime changes while the engine is running and seeing the results immediately [/QUOTE]
