So my er9 RD from 2023 just died after my bike sat on the back of my car through a rainstorm. Me being impatient I orderd an eGr RD from LTWOO official store without thinking more about it. I remember seeing a post about er9 and egr being compatible, but, now I see talk about v1, v2 and v3.Am i ok, or have a just wasted money?
