Better Than - bTres Ethanol Calculator Demo

The bTres made by Better Than is the most useful tool I have to help keep an eye on things, data log, dyno and switch tunes on the fly but its loaded with so many "hidden" features. Its a very user friendly unit and Travis has done an amazing job keeping it updated and adds features all the time.
If you have a tuned Audi running DS1 software then you really need this unit.
