Checksum Error Question

**780ripper** · 03-12-2021

hi Rick, i am using tuner pro v5 and pcm hammer 14 along with OBD link LX. I have read every pcm that i have available to me on the bench with this set up and it all worked. When i open the tune with hp tuners ( the program that was used to first tune my pcm) to view it it says that its not locked. The bin file is directly from what is on the pcm that is running my truck.

This makes no sense to me. You say you are using a BIN file in the first post above but you open the tune with HP Tuners. But . . . HP Tuners does not presently have a capability to open a BIN file . . . only a *.HPT file. So I'm lost here.

if you use HP Tuners 2.24.1172 you can look at bin files.
