ThunderMax Idle Reduction Supplement
Introduction
The following information is a guide for lowering the engine idle speed using the ThunderMax ECM in Closed loop format. Most of the base maps in the ThunderMax data base are calibrated to idle between 960-1008 rpms. To reduce the idle speed, the low speed map pages must be recalibrated. This is done by lowering the idle speed in increments of 100 rpms (or less) and running the engine to allow learning of the map pages. Once the AFR becomes stabile, you can further lower the idle speed until the desired RPM is reached.
Lowering Idle RPM
1. Open SmartLink IV.
2. Attach the serial cable from the ThunderMax ECM to your computer.
3. Turn the ignition on, but do not start the engine.
4. Link to the ThunderMax ECM and select File > Read Module Maps and Settings.
5. Display the monitor gauges for the IAC Position, the Engine Head Temperature, and the Engine Speed.
6. Select Module Configuration > Basic settings
7. Lower the Idle RPM, but no more than 100 RPMs per tuning session.
8. Depending on how low you are setting the idle speed, lower the IAC Stop Target value by 2 to 4 steps.
9. Open the “IAC Stop vs. Engine Temperature” map page.
10. Make certain that the transmission is in Neutral, and start the engine.
11. Track the IAC position during warm up in the “IAC vs. Engine Temperature” page and manually set the IAC stops to 5 steps below the actual IAC position. Do not allow the engine to idle unattended! (The following screen shot is for reference only, the values shown are not typical)
Throttle Body Calibration
If the IAC Position is below a value of 15 at normal operating temperature you will need to reset the throttle blade position in your throttle body. Remove the adjusting screw cap and adjust the blade setting screw counterclockwise ¼ turn. Reinitialize the module and observe IAC position and adjust stops as needed.
