Can't mess with the OEM computer? Fine, just run a parallel system for the motor (or a new motor for that matter). The automaker doesn't own your vehicle. They can't prevent you from changing parts out, but they may have the right to prevent you from hacking their computer software. So, just run a different computer for what you need. Certainly, the automaker can void your warranty but that is another issue.
