    U1024 code after flashing

    Has anyone experience this after flashing 370z? I seen it with uprev and is usually a device problem but with HP is the first time and even if I flash stock read file back still is there.

    Think I Found the issue, vcm scanner needs to be closed if open even tho is disconnected it will get into writing conflict

    If you do a deep scan of all your modules, I'm sure you'll have around 10 U codes of CAN miscommunication between modules from flashing.

    You'll see on some cars, these codes are disabled.
