Hi Steve,

Thanks for posting these! FWIW, you can sign up for a Hyundai Service portal account here https://service.hyundai-motor.com/ and if you pay them 15EUR for 24 hours then you can access a lot of service info including harness diagrams and module pinouts (under the "ETM" section). The site doesn't have anything inside the EPCU, it's a black box for external repairers, so no IGBT gate driver pinout. But they do have the main EPCU pinout of the big connector.

Did you make any progress with the Ioniq inverter? I just bought a wrecked Kona that looks like it has a very similar or identical EPCU stack in it. Currently working out what my plan is for that...
