I am just wondering if anyone knows if the ECM has a pin to enable AFM. I like to add a pushbutton that allows the system go into active mode instead of using the factory calibration. Personally, I think the calibration for AFM is not agressive enough. GM is probably too conservative and prefer more toward driveability than fuel economy.

If the input to AFM is not exposed on the ECM (I doubt it very much), does anyone knows if there are after-market calibration that are more agressive toward going into 4 Cyl Mode. Thanks
