the Exposure is ALL messed up...
im not shure just what you need here.................
If you want help, then you need to explain
1) what CHDK and Canon firmware settings you used
2) how the result differed from the result you expected.
i load it and i shoot with defaults the Exposure is Way to long.
What do you mean "shoot with defaults" ?
and if i go into the menu and change the Exposure value from 2048 the camera crashes 98% of the time.
Which menu, which value ? If you are actually overriding the shutter speed to 2048 seconds, that will look a lot like a crash, or maybe actually crash...
so i reload version 1659 and all is fine with the defaults and @ 2048.
What do you mean "defaults at 2048"... either it's default settings, or you have overridden something.
I suggest you take a look through http://chdk.wikia.com/wiki/CHDK_User_Manual#Extra_Photo_Operations
and make sure you understand how the overrides are supposed to work.
