Hi I have an lt1 swapped into a muscle car, it has a 95 pcm that has been flashed with a 94 bin by a mail order place in canada. I just want to chang a couple small things but I have no idea what I am doing. I used eehack to download the bin from my pcm which worked at first. When I loaded it into tunerpro it looked like a lot of things made no sense. Tables with nothing but zeroes in them, three digit numbers for some of the shiftpoints, etc. I tried to download the bin several more times but now after downloading, when it asks if i want to save the files, the "save" button just remains highlighted and it does not save it. I think it is trying to save it in the tunerpro program. Does this make sense? Also when I modify the bin in tunerpro, do I need to modify both bin files? Why are there two? Thanks
