How to remove diablo tune without device

[Diablo monterrey]

Hello,

Previous owner uploaded a tune (diablo 93 octane tune) to my car that is really bad, well not for my car. I recently bought an Intune 2020 for mustangs, but can not load any new tunes because has the old tune.

I do not have the original device. Should I just change out the ecu?

Regards

the new tool will read out a file, send that to me or post it here, its in the tunes folder on the i2 drive.

I'll get you back to stock from there.
