CHDK can write two versions of DNG: 1.1 and 1.3. Perhaps worth a try to see if changing the DNG version makes any difference.

Not having PS,  I'm afraid I can't help further.  Seems possible there should be a setting in PS somewhere that tells it to use the DNG WB info?

if exist i dont know where is located! hahah damn PS!

Anyway thanks alot for your help! :)

thanks!

The .jpeg you see up there is untouched, is what the camera records to the SD card. I didnt process anything
You said you set a custom white balance to get this result. That's processing, whether it happens on the camera or your PC. If you set your camera whitebalance to a standard setting like daylight, does the result look like the DNG?

The raw data in the DNG is... raw data. It either contains the bits from the sensor or it doesn't, beyond that it cannot be "wrong", and the removal of the IR filter will not affect this. The WB setting is not applied to the raw data when it is saved, it is recorded in a separate field in the DNG. So if you manually control the WB in raw processing, you should be able to get the same result you get from the jpeg.

The WB required to achieve your desired result is likely very far from the normal range, so it wouldn't be surprising if this confuses some software, or amplifies some bias in the color matrix. Software that doesn't use the DNG whitebalance setting will likely show you something very extreme, perhaps like what you are seeing in PS.

If you can upload a sample of the actual DNG and jpeg somewhere (dropbox, google docs etc), we may be able to give you additional advice.

DNG version shouldn't make any difference, the white balance settings and color matrix are recorded the same.
Don't forget what the H stands for.

Try change the white balance setting from the 'Como Foto ' to the 'Automatico ' (As Shot>Auto).
Settings on your picture look very strange, you can define yourself settings for WB and save them for later use as a preset.
Upload your DNG and JPG somewhere,if you want.

My humble opinion (i'm a noob at this subject) is that the PS dont find / accept the custom WB from the camera. So it give me a random WB.
In the UFRaw i can choose between the Custom WB from my camera (with the correct colors) and a WH Manual (With the wrong colors, pink)

2 DNG's and 2 JPG in the link at the end of the post!

Already did that and in PS is always the wrong WB.

That's quite possible, but unless CHDK is recording invalid WB data, that's a PS problem not a CHDK problem. The solution to that would be to use a different tool. You could probably set a workflow that batch converts to something PS can handle. Since you say ufraw handles them correctly, dcraw should as well.

Adobe's own dng_validate says your CHDK DNGs are valid.

In raw therapee, the camera whitebalance for the DNG is still a bit pinker than the jpeg. That may be due to the color matrix for this port. Just fiddling with the channel mixer got me pretty close to the jpeg. exported jpeg and settings file at https://app.box.com/s/cyyesrz68rjsmjn5hyq3
