Jano, you are completely right that modding hex is more of a workload than using a ready user interface. However, I don't see the art of finding veriables from hex as mapping. That's more like reverse engineering. When one learns what hex variables affect which settings, then it's quite quite simple again. I have no clue about pectels and such management systems, but then again, over here it's quite rare to play with the OE managements, or better yet, install OE managements to vehicles that never used them in the first place. Of course automotive legislation in UK and Finland differs wildly, but generally and honestly i just can't see the point of doing things the hard way unless one tends to sell off the self chips in numbers.
