Loading Original ECM E92

[marmourjr]

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.

When I go to Efilive Tune Tool seems that I cant do a Calibration Flash or a Full Flash

Resolved.

You got it going (did you remove the controller serial number restriction...?)...?
