Is there a gm global a ecm unlock shop in Detroit I should use instead?

Does Michigan vehicle inspection or emissions testing affect this service?
Michigan has no statewide periodic vehicle safety or emissions inspection program. Our service is bench module programming only — you remain responsible for your vehicle's compliance with all Michigan and federal requirements.
What does a Global A unlock actually do?
It removes the read/write lock on a locked GM Global A ECM so tuning, cloning, or repair software can access the calibration again. It restores access — it does not change or add any calibration itself.
Is this the same as a tune?
No. This is not a tune. It unlocks read/write access so you or your tuner can then read and write the calibration. Any actual tuning is a separate step done with your own software or tuner after the unlock.
