You need to think carefully about this (I'm not saying don't do it), but if you provide the files you are responsible (within certain limitations) for their effects they have on other peoples cars.
If you brick someones ECU etc then legally they would have a good case to sue you for the cost of putting it right. You can put whatever disclaimers you like it doesn't change the liability you have for providing products that are fit for purpose under UK/EU law.
Just beware thats all.
Also adding 1 to each number isn't going to wash if someone did challenge you for copyright (not that I think they would). So long as the content is substantially the same then copyright is still infringed.
