Of course you’re asking about the check engine light. Well, when I run the TUNE : https://www.livernoismotorsports.com/… It throws the check engine light but is otherwise unaffected. When I go back to stock tune, it’s fine. The company says that means my catalytic convertors are failing. But when I test them, they’re perfectly fine. However, it’s a common problem on these FPIUS. the regular non 3.5L ones can get a factory recall to replace them while us ecoboost people get fucked.
