is there a way to physically delete codes from your ECU

@deadbeatrec

depending on the car and software available for it, certain parameters can be deleted but you will never pass inspection. i think u can have one fail. for ex. my corvette, the parameter for the Cats is turned off. thats my one fail

with subaru’s you can turn off the certain parameter and “force” ecu readiness so you can pass. ive done this with romraider/ecuedit on my 92x and wrx.
