Ok , this question has probably been asked several times , but I did not see license break down as to how the license works .
I have a 2005 Chevy Silverado and want to tune the PCM , does the engine require a license and the transmission require a license or once the PCM is licensed , both can be done through the PCM , with out additional license for each?
In other words do you license the PCM or parts of it , engine , transmission ?
