Failed to add key 2025 Dodge Ram Sport 1500 with Autel IM608.  The secure gateway with a different connector. The 12+8 FCA gateway adapter and the Start connector cannot connect to the gateway connector.

Here is the clue.
New style gateway. No aftermarket device will program the key by OBD. The 2025 Dodge Ram 1500 (5th Gen DT, including Sport trim) has a newer style Security Gateway (SGW).

Requires a J2534 passthru device with WiTech.

Nothing aftermarket for new gateway.

Require Witech2.0 with NASTF. The nastf 4 digit pin is for witech.

You are seeing a completely different connector because Stellantis quietly overhauled the electrical architecture for the **2025 RAM 1500 refresh** (the Hurricane engine era).

The classic 12+8 pin Security Gateway (SGW) bypass cable used from 2018–2024 will **not** work on this truck.

Why the Connector is Different?

The 2025 RAM 1500 has upgraded to a new generation cybersecurity firewall utilizing **FD Ethernet (Flexible Data-rate Ethernet)**.

* **The Physical Difference:**
The old SGW relied on traditional CAN-bus pairs (which the 12+8 cable tapped into). The new module manages high-speed ethernet lines, meaning the physical pins, connector size, and wiring layout are totally redesigned.

* **The Software Difference:**
It enforces strict cryptographic authentication that cannot be bypassed by simply throwing a bridge harness between traditional CAN lines.

How to Successfully Program a Key
Because the physical bypass cables you might be used to are incompatible, the workflow for adding a key to a 2025 RAM has shifted toward **authorized software-level unlocking** rather than tearing apart the dash to find a physical bypass plug.

The Authorized Software Route (Recommended)
Instead of trying to find an adapter cable, you bypass the gateway digitally via the OBD-II port:

Hardware:
You will need a high-quality J2534 PassThru interface (like a Topdon R-Link, Autel MaxiFlash, or official Mopar MDP/MicroPod II) paired with a stable internet connection.

Software:
Use official OEM diagnostics via **wiTECH 2.0**.

Authentication:

You must have an active wiTech 2.0 account registered with your diagnostic platform. When you initiate the key programming procedure, the software communicates over the internet to officially unlock the Secure Gateway over the OBD port.

Note: If you are generating a smart key using universal aftermarket remotes (e.g., certain Xhorse or aftermarket platforms), many technicians have reported programming failures on 2025 models. For these newer architectures, it is highly recommended to use an original OEM Mopar proximity fob or a high-quality, pre-coded OE-equivalent key.

What is the difference between golden JLR Pluto VCI and new green JLR Pluto vci?
Transparent can do 2026.
and has 5 times speed more than gold.

They have the same function.
If need to replace with a new VCI, just install new driver and plug the new VCI. But the old one will stop working.

What is the difference between Mucar 892BT and the new Mucar 892BT PRO diagnostic scanner? Just same hardware but  with topology and more functions?

Here is the clue.

They come with exactly the same case and accessories. But software and license are different.

The 892BT Pro already ships with topology mapping built in.

The MUCAR 892BT does not support the Topology Map function.

892BT PRO supports more special functions (40+) while 892BT supports 35+ service functions.

Can we migrate Mucar 892 BT to PRO version by software update?

No, the Mucar 892 BT can’t be converted to 892 BT PRO with a simple update.
And here’s why:

Why is updating to Pro not possible?

1. Both versions use different licenses
Although the material is identical, the PRO version includes:

• additional software modules
• licenses for advanced functions
• access to topology mapping
• more maintenance service functions.

These licenses are paid and related to the device’s serial number.

2. PRO firmware is not compatible with the standard version
Mucar locks firmware to avoid:

• unauthorized facilities,
• software conflicts,
• stability issues.

3. Mucar servers check model before authorizing updates
Even if you manually install an APK, PRO functions do not activate without server validation.

VAG Bosch MD1CS004 H80 Unlock, Read and write tested working fine with Magic Motorsport Flex programmer.
HW80 already supported in the new update.
open only one side of the ECU.
You have manual on the flex. You have all conections in tools.
Need to remove one component (smd resistor) while unlocking then have to put back in place.

Question:
Is possible do it BMW F series coding with this Autel IM608 JVCI interface?

Theres a diagram that explains connections for BMW f/g series.
Autel make an enet to obd2 adapter. Its like an esys cable. You need it. Then you also need a usb to ethernet adapter as the enet cable needs an rj45 ethernet connection. Plug usb to ethernet adapter into one usb port, plug jvci into other one.
Turn wifi off so jvci connects via usb only.
Do NOT use a charger when programming or coding on bmws. You need a dedicated power supply to provide bulk current capacity, not so much voltage. Car can draw 20 amps just sitting there with ignition on. Theres a bunch of routines they run through during the processes, anything could be randomly switched on thatll double or triple the current draw. A battery charger cant accommodate that, itll draw that demand from the battery and the system voltage will drop. Its this that causes corruption and damage to modules.
This is why you need a dedicated power supply.

Problem:

Added a spare key today to 2022 Toyota Kluge / Highlander HV using Autel IM508s along with Autel universal key for Toyota 8A.
Backed up eeprom file via OBD, followed guided add key, and programmed in successfully.
However trunk open button not functioning.

Did eco to immobiliser sync and all other buttons /keyless entry etc working great but need to get trunk button working.

Had same issue recently with a 2023 Rav4 hybrid. Any input?

In the crowded world of OBD2 scanners, the MUCAR 892BT stands out by offering a compelling package: built-in AI assistance, lifetime free software updates, and a responsive, user-friendly interface. But does it deliver on its promises? After extensive real-world testing on vehicles ranging from a 2000 diesel truck to a modern daily driver, here is the full verdict.

First Impressions & Unboxing

The MUCAR 892BT arrives as a complete kit designed for professional and serious DIY use. Inside the well-organized carrying case, you will find:

• The 8-inch tablet scanner

• A wireless Bluetooth VCI (Vehicle Communication Interface) with a strong magnetic back

• Cables and adapters including: Ethernet for DoIP, USB-A to Ethernet adapter, and a USB-A to C charging cable

• Multiple plug types for different regions

• A screen protector and a wall charging brick

The tablet itself feels premium, with a bright, crisp screen and a handy built-in kickstand that easily props up on a steering wheel. The wireless Bluetooth VCI is a standout feature, allowing you to move freely around the vehicle without being tethered by a cable.

Key Features That Set It Apart

One of the biggest selling points is the lifetime free updates. Unlike many high-end competitors that charge hundreds of dollars annually, the MUCAR 892BT lets you download the latest vehicle software at no extra cost.

Important Clarification: If the manufacturer ever stops providing updates, the tool does not become a brick. It will continue to work on all vehicles it already supports. You simply won't be able to diagnose newer models that come out after the update cutoff. This is standard for all scan tools. 

The AI assistant is more than a gimmick. It can answer both car-related and general questions. For example:

• Ask about a specific trouble code (e.g., P0420) and it provides probable causes and fixes.

• Ask general questions like "How hot is the sun?" and it pulls up factual information.

This feature is integrated into the diagnostic workflow, making it easy to get quick insights without reaching for a phone or laptop.

The tool includes access to the Dollar Fix community—a public forum where users can post questions about their vehicles and get advice from other DIYers and mechanics. This crowdsourced knowledge base can be invaluable for troubleshooting tricky problems.

The MUCAR 892BT supports full system scanning and bi-directional control, meaning it can both read data and send commands to vehicle actuators. During testing, the reviewer successfully:

• Activated the blower motor and wipers on a modern GM truck

• Ran a relative compression test on a 2003 Ford 6.0 diesel

• Performed cylinder contribution tests on a 7.3 diesel

It covers over 140 car brands and supports advanced functions like ECU coding, 34+ maintenance services (oil reset, ABS bleeding, DPF regen, etc.), and protocols like DoIP and CAN FD.

Real-World Testing: Diesel Trucks vs. Modern Vehicles

• Auto VIN detection often fails on these older trucks (likely due to aftermarket tuners).

• Manual vehicle selection works well.

• The tool provided comprehensive live data streams (fuel trims, cylinder contributions, etc.).

• It successfully performed a relative compression test on the 6.0L, identifying a weak cylinder without needing special adapters.

• Limitations: It did not support advanced injector buzz tests or some specific Powerstroke functions. The reviewer notes that for these older diesels, specialized software like ForScan is still superior.

• Auto VIN detection worked flawlessly.

• The tool identified a massive number of modules (video processing, body control, powertrain, etc.).

• Bi-directional tests were extensive and worked perfectly—controlling HVAC, wipers, washer pumps, and more.

• The tool shines brightest on modern vehicles with complex electronic architectures.

User Experience: Interface & Speed

The reviewer repeatedly praises the fast and responsive interface. The Android-based tablet navigates menus smoothly, and the screen recording feature (built into the tool) makes it easy to capture diagnostics for later review.

• Screen Recorder & Screenshots: Useful for documenting issues or sharing with customers.

• Third-Party Apps: You can install apps like YouTube, Google Chrome, and even games (Candy Crush) directly on the tablet, turning it into a versatile shop companion.

• Customer Management: Shop owners can store customer info and generate professional health reports with their business logo.

Pros & Cons at a Glance

Pros:
Lifetime free updates
Built-in AI and community forum
Fast, responsive interface
Wireless Bluetooth VCI with magnetic mount
Extensive bi-directional control on modern cars
Supports third-party apps like YouTube
Generous 34+ service functions

Cons:
Some advanced tests (e.g., injector buzz on older diesels) not supported
Auto VIN detection may fail on heavily modified older vehicles
Requires internet connection for some AI and community features

Final Verdict: Is It Worth It?

The MUCAR 892 BT is hands-down the reviewer's favorite scan tool—even over more expensive units. It offers an unbeatable combination of features, speed, and long-term value thanks to the lifetime updates.

• Serious DIYers and enthusiasts who want professional-grade diagnostics without recurring fees.

• Independent shops and mobile mechanics looking for a cost-effective, capable tool for modern vehicles.

• Owners of newer vehicles who will benefit most from the bi-directional controls and deep module access.

Bottom Line: For under $500, the MUCAR 892BT delivers exceptional value. It's fast, feature-rich, and future-proofed by free updates. If you're in the market for a scan tool that does almost everything without breaking the bank or locking you into expensive subscriptions, this is a top contender.
