Do you have a tune to load onto the Trinity?
If so, then hook up the Trinity to your PC and open DS Downloader. Once the program has found the Trinity click on the "load tune file" button and follow the prompts. Once you have the tune loaded on the Trinity then plug the unit into the OBD port in your car and go to the performance button and load custom tune into the car.
I will PM you my phone #. Do not hesitate to call or text if you need help and Ill walk you through it. Have fun!!!
