I did a original read on my ECM92 and created a back up copy. I went an put a new tune however I am having issues with it. I am trying to revert back to the factory ECM E92, and I'm getting a $0531 Error.
I cannot drive the car due to an issue with the new tune. How can I get my original ECM on my 2014 Cadillac CTS V-Sport?
Attached is the ECM E92 that I pulled.
