The VIN was pre-programmed, so as soon as I connected it, everything synced perfectly without any hiccups. Installation was straightforward, and the truck fired up right away with no warning lights. I appreciated the quick delivery and the helpful customer support who answered a couple of my questions promptly. Overall, this made what I expected to be a stressful repair super smooth and hassle-free. Highly recommend for anyone needing a reliable ECU replacement!
