Lightroom 4 Auto Exposure

In Lightroom 3 I had presets for Auto Brightness, Auto Exposure, Auto Contrast, Auto Shadows

In a text editor the Auto Exposure looked like this :-
s = {
id = "2F383948-723B-4463-B168-77CEBC67F4B0",
internalName = "Auto > Exposure",
title = "Auto > Exposure",
type = "Develop",
value = {
settings = {
AutoExposure = true,
},
uuid = "FBA6F912-139D-4373-94C5-E349FD96F89B",
},
version = 0,
}

I have tried to replicate this in Lightroom 4 but with no luck. Any one here have any ideas?

try under camera calibration change process to 2010, run the preset, change the process back to 2012, then click on the + button on presets and make sure process is checked off.
that will update your preset to the lightroom 4.0 2012 process

Thanks for the reply, but unfortunatly that does not work
