The block is actually determined by the ECM type. For the Cummins and Bosch based Duramax ECM's we can stop just reading, yet allow them to be reflashed, this is the ideal situation (as far as locking goes).You have the cummins and dmax markets locked up. However, On a gasser platform, does the read blocker work if another manufacture tries to read the ecm, or is it just a bit you flip to prevent other efilive programmers from reading the data?
For nearly all the gassers and LB7 & LLY, the lock prevents everything, reading and flashing (including dealer updates), there is no back doors. Again, this is because of the architecture of the ECM it has to work that way.
The lock we are talking about is done to the ECM, not the tuning file.
I've seen first hand in the gasser tuning world, unlocked tunes are usually used for forum hero ammo, not learning, so I totally understand why tuners want the feature.
