I am not sure we can program the FS2 HHO Chip for the 2015 on your Ford Escape. I did a little research to try and find out if the 2014 ecu was the same as the 2015, but can't be sure. You may want to ask your Ford's Service Dept. If it is, we can.
But even if we cannot, the EFIE is a great way to go also. We will supply you with the correct one. Please remember to include your vehicle's info.
Please feel free to contact us with more questions.
