Toyota Tundra 2007

Hello friends:

I have a Toyota Tundra year 2007 5.7L The problem is that I change the ECU and I get a check requesting the reprogramming of this, in the dealer they told me that when it is in new (ECU) it is not necessary that it is rescheduled with original scanner for Toyota.

Does anyone know any trick to correct my new ECU right?

I have a Scanner Bodch X431.

Sincerely,

Roberto.
