Default used ECM replacement "help" vin registration

its a 2006 is250

I had to replaced my ecm in the engine bay. I bought a used one because a new one would cost $1000+ .. Car runs and dies because of used ecm is registered to the previous vin.

I was wondering is it possible to Re-write the vin number in a used ecm that vin has already been burned to ecm.

the place i bought the ecm from said theres people that have bought a few is250 ecms before and never came back to return it... so there should be a way somehow to re-write the vin huh?

i'm about to take it to lexus to get the vin registered, but dont want to end up being told ecm needs to be replaced with a new ecm thats in registration mode.

A dealer has to use their Techstream scanner to register the VIN to the new ECU.
