I have made my way from the darkside. Since the Ford is down, I needed a tow vehicle. It's a GMC Yukon. Driveway engineer video gave pretty decent instructions on pulling the bin and tuning it. Enter someone else's monkey wrench. The ecu has been locked. OS is 12589250 and I cannot find an xdf. So if I force unlock it and extract the bin, I'll need to re-flash the OS as well as the bin. Any insight would help as this is new to me. The verbiage is much different from fords and audis. Concepts the same.
