Hi all, I read my stock 2732a just fine, but when i try to read the 27fs512 that i have a custom burn on and look at the parameters in tuner pro all the maps read 0. I have most of my bins backed up but I ended up losing the one that I am currently running and would like to read it and back it up.


Thanks
Ian

Offsets are different when the bin file is same size and chip size is different. This should help get the bin on correct part of chip.

Thank you, I just figured it out I was using that guide but was using the the HEX from the 16K thinking it was for the 4K, basically reading the wrong line
