    How do I read the knock sensor info from OBD port for Subaru

    A: It’s not part of the OBD standard, so you need a Cobb access port to read the data

    Okay but I don’t have money for that and I’m literally just making a python script to do this.

    A: Well you need the custom ID to query the sensor info

    Okay what’s the custom ID?

    A: You have to pay morbillion dollars to get access to the documentation that has the custom info that you can get from the ECU

    Not even close to doing anything with tuning ot modding, but you’re telling me I can’t even read a sensor because neither Subuaru nor Cobb will tell me a single hex ID bruh
