I am looking at ordering the BT aldl adapter and the app. Two questions.
1. I have looked with no luck. where is my ecm for a 91 burb 5.7
2. The app says make sure you have the Adx file from tuner pro before purchasing. I can find the xdf but no adx.
3. I plan to use BT to my tablet but tuner pro well be on a Older laptop that only has usb. I am guessing I could save the files on the tablet then transfer them over to laptop?
