I know I've been silent for a bit but yay, I'm returned!
I've now installed the ECT Spoofer that's available over at Prius Chat. I'm not sure of it's effectiveness yet but it does work as intended I can say that. I'll do some more messing around with it later on to make sure. And post some pictures as well. Along with the story of me setting off, I think, every error code the Hybrid system has to offer. So nothing but good times and laughs ahead
