Black Box PCMs

"Gen 3" PCMs

The Powertrain Control Modules released to control Chevy's 3rd Generation Small Block V8 Engines, as well as other engines of roughly the same era (1996-2008).

There is no good nickname for these PCMs like with the Black Box series, but a lot of people seem to call them Gen 3 PCMs.

Identification

Gen III PCMs (like others) have a pair of identification numbers by which they can be differentiated.

Service Number

This is the top number on the label, abbreviated SERV. NO. on the printed label.
