Has anyone retrofitted a gearbox steering wheel paddle shift to an Insignia before? I saw a steering wheel with paddle shift for sale, and I'm wondering if it's a direct swap to an automatic insignia or what would be needed to retrofit it to my car.

Hello, does anyone have calibration files or DPS package for 2013+ volt with bose/without nav? I have a 2011 Volt, it does not have Bluetooth audio, and I have a used MyLink unit from a 2014 Cruze I want to install that has it. The Cruze mylink unit does work, but it doesn’t communicate with the Bose amp, the main controls are not mapped correctly (climate somewhat works) and I can’t access any fuel economy info.. but at least the BT audio connects 😀

I am trying to create a type4 file to correct mileage on 2019 Escalade. I followed the guide for creating Type4 but still running into issues.

Hello everyone, in order to make UJM work on my dashboard, I downloaded the firmware from VIN W0LPD8EC1E8071509 into it. The car configurations match as much as possible, except that I have an electric handbrake, and that car had a mechanical one. Is it possible to enable the J71 option in the dashboard via the xmlfile? And if so, what lines do I need to add, I have several xml files from different panels, but unfortunately they don't have this option.

Hi Has anyone managed to enable the oil temperature reading on this small black screen so that it shows the real values in a 2016 Astra K 1.4 turbo 150 hp?

Hello, I bricked my Astra J 2014 IPC by getting rid of TPMS. Has someone the following calibrations and is willing to share? OS: 13409393 HMI: 13422795 Graphics: 13422796 Warning: 13421680 or complete IPC package for VIN: W0LPF8EN8E8015224 including Utilityfile. Thank you so much. Toby

hello i have gmc 2024 sierra I have a used ECM. Is it possible to disable vats option to start car the same global A? thanks

All the buttons on the right side of the steering wheel for media and volume stop working. Also, the mobile phone talk and mute buttons on the left side stop working. None of the ambient button lights works on the steering. Has anyone encountered this issue before? Can they let me know why I have this issue? All the cruise control buttons still work. Before I had this issue, all I did was remove and check the fuses in the glove box and the engine bay.

Update 21/February/2026GM GDS2 Infinite Lease File GM GDS2 software version that will work with the Infinite Lease File I have a member who's trying to install ACDelco's GDS2 infinite lease. The previous folder that stored the licence file is no longer there. Does anyone have info about it? I haven't used ACDelco's GDS2 in a long time, so I can't check my PC.

Hello! I have one Silverbox module wich stuck at boot logo cant react to anything. Tried SPS not help usb method not help cant run update file. I think EMMC dead. I see the modul front there is a 4 pin white connector what is that? External usb port or UART? I want to check in PuTTY the boot log. Is that possible? Can i repair the emmc file system and use it to new emmc chip? It is possible to repair the software from usb update files? Anyone has raw img for emmc? Or any possible method to force update over dps or uart commands? First i have to find UART port. Thanks!

If you install a used IPC in a vehicle, more than likely the vehicle's mileage will not display on the IPC screen. You will need to do two things in order to get it working. You will need to change the VIN number in the used IPC to the VIM number of the vehicle. You will need to use GM SPS service to reprogram the vehicles keys (this is optional but if not done you will receive an IPC DTC). Use my custom DPS files to quickly change the VIN number in the IPC module. VIN change file for most 2-byte IPC VIN change file for most GMC 2-byte IPC VIN change file for most 5-byte IPC …

Good day, Fairly new in programming ECUs, for 3 long days I've managed to find out how to program my 2013 Cruze JH Transmission ( 6t40 ) but seems it wont continue, in SPS2, even in DPS, i have the correct Archive data. but seems like still wont continue, Please help. Thank you! problem.Txt

Hey i ask my self if it is posible to retrofit on an astra j from 2011 with LDD to retrofit KL9. I meen i know that almoste everthing can be programmed but i ask me what ECU has to be reflashed? Only motor controller or also the BCM? If so can anyone Tell me what calb file in bcm needs to be reprogrammed? Because i have retrofit rain and light sensor so the default calb for my vin does not work. Only if anyone ask i know start stop is maybe stupid it is more for fun to see what is posible.

Hey everyone, I’m working on retrofitting OEM ventilated and massage seats into my 2022 CT4-V Blackwing (Global B) using factory donor parts. After speaking with a dealership tech, I was told: My VIN controls feature enablement in the BCM Since my car didn’t come with vent/massage from the factory, the BCM won’t allow those features Even if I program vent-capable K40 modules to my VIN, the BCM may still block the function Using a donor VIN in the BCM could trigger theft deterrent / immobilizer issues So I’m trying to figure out if there’s a clean way to enable these features without changing the BCM VIN, such as: BCM feature flag overrides Calibration edits Engineering-le…

Hello, i want to ask if is Posible to Start an HMI2.5 on a Bench without the BCM. The IOB did work whene i Press the Powerbutton even without the GMLAN. But the HMI uses Highspeed GMLAN an the Display and Radio the SW GMLAN. I think it sould be Posible because even if the Car is Turnd off the Radio sould Function or? Thanks.

Hello guys, Can anyone make calibrations for US to EU taillights conversion on these cars? I can provide the cars VIN if it is needed.

Hi, I’m looking for a GM engineer or specialist who can explain how the matrix headlights work on the XT6 or Escalade (so far, these are the only two gas-powered vehicles that have this option). My vehicle has upgraded headlights (3-lens, matrix), and when the vehicle starts, the LED zones turn on and off as part of a system test. However, the feature is disabled due to road regulations in the U.S. market, though it may be enabled in the Canadian and European markets. I compared the front camera calibrations (which appear to be the same as the Canadian version) and the K26 module calibrations, and I found that the difference is in a calibration related to Advanced Forwar…

Hi guys I’m facing an issue while testing the V-Series cluster theme on my vehicle, and I would like to ask for your guidance on how to resolve it. I own a 2022 Cadillac Escalade Sport, and I experimented by applying a V-Series VIN configuration to the digital cluster. The V-Series theme did successfully appear on the cluster, and visually everything looked correct. However, after applying this configuration, every time I start the vehicle I now receive the following message on the cluster: “Service Steering Column Lock” Based on my understanding, the steering column lock feature is exclusive to the Escalade V model, and my vehicle does not physically have this hardw…
