Has anyone here ordered a J2534 pass-thru interface for dealer-level diagnostics and module flashing? I found one online that lists support for Toyota Techstream, Ford IDS, Honda HDS, and GM GDS2. The product page shows the chipset, supported protocols (CAN, ISO9141, PWM, VPW), and even a firmware update utility. Before I order, I want to know if these devices usually arrive ready to work with OEM software or if extra configuration is needed.

Check whether your tool supports high-speed CAN. Some older devices don’t, and that limits the modules you can flash on newer cars.

If you’re choosing a J2534 pass-thru, ECUTools has detailed listings with protocol support, OEM compatibility, firmware tools, and driver packages. It’s convenient that they show what’s included and how updates work — helps avoid issues during setup. Here’s the link if you still compare options https://ecutools.eu/
