GM DPS vs GDS2 Software

What’s the difference between GM GDS2 and DPS software?



GM Development programming system, aka DPS, is an in-house software general motors technicians use to develop software for GM motor vehicle electronic modules. DPS functions similarly to the GM SPS client. By itself, DPS can only perform the basic functions of reading the ECU ID information. You must acquire the corresponding calibration files and custom DPS scripts to complete any DPS programming.

You must have a GM compatible OBD diagnostic interface for connecting DPS to your vehicle, such as the VXdiag VCX NANO GM, DrewTech Mongoose pro-GM2, or GM MDI-2 interface. Any diagnostic interface compatible with the GM GDS2 diagnostic software will work fine with DPS. You need access to the GM SPS service to gather calibration files for your GM vehicle electronic modules.
