GM Development programming system, aka DPS, is an in-house software that General Motors technicians use to develop software for GM vehicle electronic modules. DPS functions similarly to the GM SPS client. By itself, DPS can only perform the basic function of reading the ECU VIN and basic information. To program a module using DPS, you must acquire the corresponding calibration files and custom DPS scripts to complete any DPS programming. Only limited information, and no complete documentation, is available to the public on using DPS. All the information posted on this website about DPS was developed over time through a routine trial-and-error process. Note: You must have …

Hey, can I kindly ask you for wise suggestions and help? Will start with a description of my way so far, if you find it lengthy - just scroll down to the bottom where you can find questions. It all started 2 years ago when I bought a 1st car. As an engineer I had an idea to choose not very pricy one that will teach me fixing mechanical problems, also I can become familiar with electrical side of it, and finally programming. And it all worked quite good, I spent some amount of money for fixing and replacing broken parts gaining priceless experience and slowly I came to adding new 'features'. So, I'm happy owner of Chevrolet Cruze G1 (J300) 2009…

Hello team, I would greatly appreciate it if someone could help me. I am looking for CAL file 84336579 for the IPC Equinox software. Unfortunately, it is no longer possible to download this file from SPS because it has already been replaced with a newer version. As a result, my IPC is currently not working. If anyone has this CAL file or knows where I can obtain it, I would be very grateful for your help. Thank you in advance.

Hello, is it possible to change the software in the Opel Insignia window regulator module to change the UK to the EU ?

Hi everyone, I have a 2023 Cadillac Escalade bought at a US auction as stolen/salvage title and imported to Europe. The car won’t start and is showing DTC B1977 (Telematics Requested Immobilization). OnStar module is fully bypassed and physically removed. The code now appears only in the BCM. Questions: Does anyone have a working solution for this problem? Will replacing the BCM with a new one fix it? Any advice or experience would be greatly appreciated. Thanks!

Hi guys, I urgently need help with an Opel Insignia A BCM programming problem and I am running out of time. Vehicle: Opel Insignia A VIN: W0LGT8ES8E1199586 I accidentally ended up with the wrong BCM software/calibration configuration and now I need to program the correct target calibrations. I have already spent a lot of money on SPS tokens trying to solve this, but SPS keeps stopping with: E4419 – Unknown control unit software detected, possibly a newer version. Programming procedure aborted. At this point I really cannot keep buying SPS tokens just for another failed programming attempt. I have GM DPS installed and working, and what I urgently need is someone experienc…

Hello everyone. I came up with the idea of enabling remote window opening on the first-generation Chevrolet Cruze. Has anyone managed to do this? I compared the calibration files for the Cruze and the Mokka (specifically file no. 11) and made some changes. All the windows open using the remote, but only the front ones close.

Hello, GM EPC Global has been replaced and is no longer accessible at https://www.gmglobalepc.com/ It has been replaced by gm parts connect. which appears to be entirely web-based. If anyone can access it through the ACdelco TDS portal and knows the URL, could you please share it? this seems a internal domain url Thanks!

I have a custom Hummer H3 that needs the VIN numbers on modules changed to match the ECM. The hummer over laps the architecture change from GMLAN to Global A. Will the GM DPS work on these modules that overlap this timeframe? If not would anyone have any ideas on how to modify the VINs in the Hummer. I have a 2009 E67 ECM in my 2006 hummer and I am trying to get all of the modules to play nice with it. GM used two different ECMs in the hummer. 2006-2008 use one and 2008-2010 use the E67. Most all of the modules are the same between all years except the programming in them.
