My ecm has issues and I need to remove the EFI live so I can replace the ecm and reinstall EFI live on my new ecm. How do I go about doing this?

Do you have an EFILive FlashScan or AutoCal cable? Did you self-tune your truck or purchase tunes from a tuner/shop?

Ok, I moved your thread to Tuning->Diesel->Duramax LB7 where it will get more traction.

It doesn't work in the way of "return to stock" then reused on a new ECM.

The tune and a VIN license will need to be updated/purchased for the new ECM.

What SASDakota said ... IT's not like a hypertech or SCT programmer where you can reclaim the tune. you need to save a copy so you can reflash it once you have licensed the new pcm.

If you send your ECM to me, I can diagnose the status of it. If it has not been locked by an EFILive cable, then I can flash it to your factory configuration using your VIN. If it is locked, then you will need another ECM, which we stock.

Didn't efi just release a tool to unlock said key and format the CAL area to be reset with stock or tuned cal?
