1. Warm up car
2. Turn engine off and REMOVE THE KEY
3. Disconnect negative lead from battery and turn head lights on( this removes the capacitive charge in the system)
4. Connect negative lead to battery
5. Back off the stop screw on the throttle body
6. Start car
7.While grasping the throttle lever with your hand, give it a small amount of throttle and let off SLOWLY.
8. Adjust the stop screw to just meet the lever and give it another 1/8-1/4 turn and, then lock it down.
9. Turn ignition off.
10. Turn key to "ON" position and check TPS voltage. Set to .980 Volts with a Digital Multimeter (Fluke Meters are the most accurate)
11. Turn key off.
12. Repeat steps 1-4 to reset ECU.
13. Turn off Adaptive Learning in your tune so you can make the proper adjustments without the ECU making them for you. (Your tuner should know how to do this)
14. Datalog ISC duty cycle: this value tells you how much the IAC valve is having to stay open in order to control idle. ideally you want to be around 35%.
15. Datalog Idle air integrator- this is a value that correlates with the idle air neutral table values in your tune. They should be fairly close to zero. If it’s negative then you need to take air out of the ISC tables, if it’s positive then you need to add air into the tables. It’ll never be exactly zero. Allow the car to be at operating temp and idling for a few minutes before making a decision on this. In layman's terms- the integrator could be telling your ecu that more air is coming in than what is actually coming in- causing your high idle.
16. Turn on Adaptive Learning in your tune and drive car as you normally would so that the ECU can relearn again.
This process alone would take weeks, probably months. Every time I request an update from my tuner it takes over 2 weeks it seems. Heck I've had my whipple on my car for ahh over 2 months now and I've yet to even drive the car. Each tune revision gets closer and the mixer gets closer to a driveable state but with 2 plus weeks between updates it's gonna be next winter before I can drive this car.
So today I said fug it and called SCT and ordered the software to tune the car myself. Racers Pro or something they called it. So anyhow hopefully I can get the idle corrected on my own now and get this sucker rolling.
