Black Box PCMs

[edit | edit source]

"Gen 3" PCMs

[edit | edit source]

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

[edit | edit source]

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

Service Number

[edit | edit source]

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

Hardware Number

[edit | edit source]

This is the bottom number on the label, abbreviated HDW. NO. on the printed label.
