Galletto 1260 for remapping

[XM5ER]

Does anyone have experience of using these for remapping? I was just about to do a home remap on my Merc and whilst casting about for a reputable file service one of the people I spoke to advised me that the tool is a bit unreliable and prone to crashing during an upload.

Does anyone have anything to say about this, true, untrue, etc.?

Should I even consider doing this myself? (I don't see why personally so long as I have the right tool).

Thanks for your thoughts on this. The chap I spoke seemed to think that it would download info quite well but crash on the upload resulting in the CPU having to be removed and reset on a board. Have you used MPPS on a Merc at all?
