SGW 2025 Ram 1500 Big Horn

[radamoni]

Just saying you could do a great service for people and make a killing if you sold this service. 99% aren’t willing able to be this awesome, me included. Thank you and please keep us posted with success stories and the such.

I would stick with topdon because idk how compatible or picky witech will be. This was listed specifically as support and definitely better than expensive official micropod.

Amazon.com occasionally you can find it for 175-200$ on amazon and ebay sales.

I do feel your pain about buying all these scanners lol. I have a desk full of them since there is no one size fit all solution. I don’t even do this for living but after a couple of uses instead of dealership that charges me minimum 110$ish per hour it pays off.

If you have a good reasonable dealer and tech who will work with you then they might be better option but thats just not my case plus most of this is so new they will say 25+ vehicles can’t be modified or add stuff to bcm configs like before.

I love that you figured this all out and accomplished it yourself at home. I am in same boat interested in doing it for my personal 25 Rebel. I've coded and tuned every vehicle I've owned and disappointed that now this 2025 is all locked out. The only plus side to this is it will stop all those guys breaking in through the back window hooking up a bypass cable and to obd and programming a key in your driveway and driving off. So as much as we are locked out for alfaobd BCM coding they are locked out too for programing keys.

The supported top don.
MX+ for alfaobd, splitter but then xtool to have a more stable unlock status while programming.

So it didn't work without paying for tech authority in addition. Too bad would be nice to have it work for 30 days.

Maybe if I can befriend a cool dealer tech and pay 1 hour labour to do proxi after, but can you even drive it without proxi after programing BCM, etc.

As far as key programming goes everyone is locked out lol before we could read pin and use that to do it but now Chrysler had made it strictly for locksmith and dealer only to do read pin. Now that doesn’t mean you can’t program key with Witech but you will need the pin from dealer or someone with locksmith account and they made it a complete rotation key so there is no master key like we had before. It’s constantly changing.

With the auto auth they have all the tool manufacturers on monitoring so if anyone tries to do anything with security they loose auto auth access. I know Topdon had lost it for a while because they were giving more access to advanced diagnostics than what Chrysler wanted since they want everyone to use their Witech for advanced stuff. So there you have it as to why nobody is making a one size fits all solution. I did talk to a few tool manufacturers and the auto auth is what they blamed for tools not doing much.

As far as vehicle working goes sure you can drive around with minor bcm or module changes and without proxi alignment. You will just have flashing odometer and maybe a few lights depending on what you changed. Some module changes might fail initialization unless proxi is done so keep that in mind.

$500 to the outfit that puts this nonsense to bed and produces a single, integrated tool/software suite that allows me to DIY and tune my vehicle as God intended, without all the Red Team/Blue Team . Does anyone from JScan or AlfaOBD lurk these pages?

 

[gofish]

For the record, all this AutoAuth/subscription paywall BS sounds like a major Right to Repair violation to me. Prove me wrong.

I see that the RLink j2534 has the alfaobd file so you can connect alfaobd with it. Have you tried running the Proxi alignment through it with alfaobd yet, to see if it’ll be successful being that the RLink is CAN-FD?

Yes the Rlink is fd and it does show alfa drivers listed in its driver portals. I don’t have windows version of alfa so haven’t tried it. Maybe someone can let us know from here

They are not blocking your ability to diagnose and repair your vehicle. Remember, what we’re doing falls beyond the scope of repairing our vehicles, to modifying the configurations in the modules.

I fully agree with you on that. But unfortunately a lot of manufacturers are getting away with this.

Alfa and jscan are based on cda6 and i have tried that as well with some processes and its not successful at all processes. Plus from what i have heard cda6 was stopped in 23 in favor of witech which is a online only portal to get subscription money.

I do email alfa and jscan sometimes but never hear back on adding support. Plus they need to get approval for auto auth since there is no bypass cable for this new sgw stuff which is highly unlikely to be given for modification and diy tools.

Here's some verbiage from a bill that, while currently dead, exemplifies what "Right to Repair" typically denotes:

Alaska State Legislature

Sec. 45.45.800. Digital product diagnosis, maintenance, and repair. (a) A digital product manufacturer shall, as required under AS 45.45.800 - 45.45.890, make available to an independent service provider or owner of a digital product manufactured, sold, or leased by or on behalf of the manufacturer any documentation, parts, and tools necessary for the diagnosis, maintenance, or repair of the digital product.

Sec. 45.45.810. Security features. If a digital product contains an electronic security lock or other security-related feature that is disabled during the diagnosis, maintenance, or repair of the product, the digital product manufacturer shall make available to the independent service provider or owner of the product the documentation, tools, and parts necessary to reset the security-related feature. The manufacturer may use appropriate secure release systems to make the documentation, tools, and parts available.

Sec. 45.45.830. Terms of providing documentation, parts, and tools. (a) Except as provided in (b) of this section, a digital product manufacturer shall make available to an independent service provider or owner of the product
[...]
(3) the tools required under AS 45.45.800 - 45.45.890 without
(A) charge, except that, if the provider or owner requests a tool
in physical form, the manufacturer may include a charge for the reasonable, actual costs of preparing and sending the tool;
(B) requiring further authorization or Internet access for authorization for full use of the tool;
(C) impeding access or use of the tool to diagnose, maintain, or repair and enable full functionality of the digital product; and
(D) impeding the efficient and cost-effective use of the diagnostic, maintenance, or repair functions of the tool.

It's not just "repair" in the strictest terms and definition of that word alone; it's also diagnosis and maintenance. I didn't sign a EULA when I purchased the vehicle, key word there being "purchased"... Just sayin'

That's the crux right there. The SGW is a profound impedance and obstruction to simple maintenance and diagnosis, and Ram provides owners of their products with zero facilities to manipulate this module or defuse it while maintenance is being performed.

The future implications of this and similar circumstances of what effectively amounts to limited ownership are pretty significant if you think about it. Keep letting manufacturers do stuff like this, and pretty soon you won't actually "own" anything at all...

[/Soapbox] highjack complete. Sorry

That’s the last I heard from Alexi at alfaobd- he said he was trying to figure out a static gateway unlock to do through alfaobd before he officially adds the 2025 Ram 1500 to alfaobd.
It’s become obvious that’s not going to be possible.
I’ll see if he’ll give up on that, and just put all of the 2025 Ram modules and procedures from cda6 onto alfaobd, and people will have to live with using a splitter and autoauth to unlock the gateway.
That way, we don’t have to fake the alfaobd connection as a 2021 WL, and ALL of the Ram specific settings will be available.

 

[Jimmy07]

But they do- the SGW has always been able to be unlocked via autoauth since they started using them in 2018.

Charging owners a non-trivial sum of money to arbitrarily "unlock" essential maintenance functionality for three whole days is akin to taxing my constitutional rights. Just my .02.

It’s not for three days. You are confusing autoauth with tech authority. Two different subscriptions for two different things.
Autoauth is $50 a year, and you can register up to 5 tools to it, and unlock the gateway on unlimited VINs.

I'm grateful for everyone here who's attempting to overcome this as best as the circumstances will currently allow for, despite all the obstacles.

They are also confusing maintenance with modifications. No one is keeping us from doing maintenance.

Changing OEM configuration settings that are built into the vehicle's software and exist as-built from the factory? I'll take that courtroom argument any day, my good sir.

Then you will lose. Because if that was the case and a valid argument, big companies like Diablo would be suing manufacturers left and right knowing they would win.

 

[Jimmy07]

Changing OEM configuration settings that are built into the vehicle's software and exist as-built from the factory? I'll take that courtroom argument any day, my good sir.

If it wasn’t for the existence of alfaobd and JScan, who have modeled their apps from pirated proprietary engineering software (to include other manufacturers like forscan for ford, etc), it wouldn’t even be possible to make configuration changes to your vehicle at all.
Without those apps, if you wanted to to do something like swap out the 8.4 radio to a 12” radio, even the dealership can’t program the vehicle to make that swap work with the tools and software provided to them by the manufacturer.
