Bin files for 1227747 ECM
Bin Files for 1227747 ECM.
These are known good bin files with no recalls from GM. There are many BCC/Chip bin files all over the internet that have been recalled by GM and updated. Why start with a Chip/Bin that has issues to start with?
There are many more good ones, that I will add in time but this should cover any TBI conversion to start.
