G1X and CHDK

I was disappointed that you have to bracket in manual mode if you want to keep the aperture fixed where you need longer that 1 second exposures so I thought I would try CHDK. I have tried several hdr scripts and tried many different settings tv, av, iso, disable override (very confusing) and I get the bracketing to work in tv mode fine (aperture changes) with no problem. I just can't seem to get the shutter speed to go longer than 1 second. I can't even seem to get the iso bracketing to change in av mode. Do I have the settings wrong or does the G1X just not allow longer bracketed shutter speeds? What I am trying to get is 3-5 bracketed raw files by keeping the aperture fixed?

Any help would be appreciated as this has been driving me nuts and I am ready just to give up and try manual bracketing!

I appears all G series "suffer" from the 1 second limit in Av.

I was afraid of that!

Anyone able to override the 1 second exposure in aperture priority mode with CHDK. Why would Canon even place this limit on the G series cameras. If anyone familiar with chdk has any hints on the various settings they would be appreciated.

Sad to say I use CHDK but only for the timelapse function. I should expand my horizons, or in this case my bracketing

Update - after reading CHDK for dummies several more times and numerous trial and error attempts to use bracketing while keeping a constant aperture I finally figured it out. I ran across this before when using a light meter and remembered their terminology was opposite what most people think when talking about shutter and aperture priority. When CHDK is set to change tv time value the shutter speed is what changes. By putting the G1X in manual mode I was able to obtain three bracketed shots with one click of the shutter at a constant aperture of f8 of 30 seconds, 60 seconds and 15 seconds. The tv bracketing was set at 1 ev. Here is the link to the CHDK for dummies; scroll down to bracketing http://chdk.wikia.com/​wiki/CHDK_for_Dummies. Although the longest exposure I was able to get was 60 seconds; it sure beats 1 second! Have fun!
