I got my hands on a cheap used 2015 SX ECU that matches my car. Scanner can connect to it etc.
It can read the Vin#, check DTC, program key fobs, it just won't start. The write a new vin# feature doesn't allow for a new vin to be written and it doesn't allow access to the immobilizer.
Is there a reset procedure to program in a new vin#?

Many modules these days are coded to the car at the factory and can't be programmed into another car. There are places to send it where they can wipe it clean so it's like a new module but that's for a limited number of makes and models.
