Working on a 350 SBC pretty stock. Car drives well, but the idle sometimes hunts as much as 100-200 rpm. Injector pw stable, but seems like the IAC overshoots. When looking in manual, you can adjust derative, proportional and integral term, but my software which follow the new Commander doesnt have these adjustable. Everything looks the same as in the manual, but these 3 are missing. Have searched for newer software, but with no luck. Have version 3.0.7 software.
Have tried with different ign advance, with and without idle spark control, but still hunting.
Anyone?

Thanks

You need to click the "Advanced User" option on the 'Version' screen (under the 'About' tab).
