FormulaFlash Read Audi Simos 18.1 ECU in Boot

The Task: SIMOS 18.1

On the table we have an Audi SIMOS 18.1 ECU. Virtual reading doesn’t work in this case. We need to save data inside.

The Process: Boot Mode Reading with FormulaFlash

We’re waiting for the unit to heat up, then we’ll open it and pull everything out in boot mode — everything that’s inside. For the tests, we used the first unit and all the wires we possibly could.

Let’s check it. Right now we have this menu. Let’s try to connect. Power to the unit is on. It’s jumping. The process is underway. Waiting for a connection.

Power supply 13.6V.

Well, it read the EEPROM quickly. Now it’s reading the flash. Everything — let’s save it.

Checksum Verification

Formulaflash informed us that the checksums after the modification are naturally incorrect. It asked: “Should I fix it or not?” We answered: “Yes.” So it fixed it.

Now let’s check how well it calculates the checksum.

The Verdict

The FormulaFlash handled the job flawlessly in real-world conditions. From reading the eeprom and flash in boot mode to correcting the checksums after modification, the unit performed exactly as needed. A new beast in the gang, and it’s already proven itself in the field.

3 Major Changes of Thinkcar 689BT Pro

 If you're in the market for a new automotive scanner, you've probably noticed the Thinkcar 689 BT Pro and wondered what makes it different from the base 689 BT. Here's a breakdown of what actually changed — and whether those changes justify the price difference for your shop.

 

What Stayed the Same

Let's start with what didn't change, because it matters when you're weighing the upgrade. The hardware is essentially identical: same 8-inch screen, same resolution, same battery, and the same 4 GB of RAM and 64 GB of storage. The operating system hasn't changed either, and the maintenance functions and diagnostic database are practically the same. Thinkcar still follows its lifetime free update model, with the brand promising free updates until 2031 — likely due to hardware limitations. All vehicle software, maintenance, and application updates remain completely free of charge. 

The Three Major Changes
1. The New VCI with J2534 Compatibility

The biggest hardware change is the vehicle communication interface (VCI). It's noticeably larger than the base model's interface, and it now features a USB-C connection on the bottom that is characteristic of a J2534 device.

Why does that matter? A J2534 interface opens the door to online programming and reprogramming work. For shops that want to expand beyond diagnostics into programming, this alone could justify the upgrade.


2. Network Topology Mapping

The second major change is the addition of network topology — a visual mapping of the vehicle's modules. Instead of just a list of systems, you get an interactive diagram showing how modules are connected. You can select everything and run an intelligent scan, or interact with individual modules directly. The base 689 BT only offers the list-based interaction; the Pro adds this visual layer that makes it easier to understand the vehicle's network at a glance.


3. Improved ThinkAI Artificial Intelligence

The third change is the enhanced artificial intelligence, branded as ThinkAI. When you click on a fault code while connected to the internet, the AI agent provides:

• The fault definitionThe fault level (moderate or high)
• Fault symptoms
• An electrical system check and test
• Component testing
• A repair guide
• A reference scheme on the side

It's essentially the same AI that existed before, but improved. The integration with fault codes is seamless — you click on a code and get a guided diagnostic path. For technicians who need help interpreting fault codes and planning repairs, this is a genuinely useful feature.

What About SGW?

One thing to be aware of: the cost of SGW unlocking within the scanner has gone up. Thinkcar now charges $2 for a one-year SGW unlock. If you purchase the unlock directly inside the scanner, it costs 199 for a one-year release. For shops working on Stellantis group vehicles, buying from a dealer that includes the first year of SGW unlock can save you money.

So, Is It Worth It?

It depends on your goals. If you just want a scanner for diagnostics — reading and clearing fault codes and performing bidirectional tests — the base 689 BT will handle the job just fine. The Pro version doesn't change the core diagnostic experience much.

But if you want more capabilities, the Thinkcar 689BT Pro delivers. The J2534 interface opens up programming work that can generate real revenue. The network topology makes diagnostics more intuitive. And the improved AI helps technicians work through fault codes faster. For shops that want a scanner with a wider range of possibilities, the Pro is a solid investment.

Thinkcar's Thinkscan line has always been about diagnostics, and the Pro version stays true to that while adding meaningful upgrades. If you're considering one, weigh the price difference against the extra earning potential from J2534 programming and the time savings from topology and AI. For many shops, the math will work out in favor of the Pro.

EngineDance X5 Adds Ford SID212 SID212EVO ECUs

 EngineDance X5 ECU Flasher released Ford Continental SID212 / SID212evo ECU protocols.

• Full OBD & Bench support 
• A rich set of features is built into our protocol: it supports recovery mode, no patches required , and compatibility with OEM tools.
• In-house Ford tuning: faster turnarounds, full control.
• No patch required.

 

How to Use EngineDance X5 for Deutz engines?

Problem:

I will mostly use the EngineDance X5 heavy duty scanner for diagnostics. When possible I will use engine diagnostic port like on this Deutz engine. I will monitor the engine operation while the engine is running and the ECU already has 12V. Can I connect only CANH and CANL ?

 Here is the clue.

No additional power supply is required.

It does not have dedicated Deutz engine connectors.

Simply connect the four wires to the jumper box: GND, 24V/T15, CAN-L, CAN-H.

Check the pinout below:

Follow the pinouts above to connect jumper wires with jumper box (red VCI) and Deutz engine diagnostic connector.

Then run EngineDance diagnostic software to troubleshoot Deutz engines.

What Tool to Program Ford Transit Custom VW Style 5D Key?

Question:

It’s a 2025 Ford Transit Custom with VW style 5D smart keys. Is it enough to program VW 5D blanco key or it need buy only from dealer with immo data. What tool to program a new 5D key?

Here is the clue.

Need to be dealer key.

Order key through Ford and program with FDRS (Not by ODIS).

FDRS doesn’t program self made key, because key ID is not on system and xhorse/keydiy cannot read old ID on car. Like vag car.

Dealer key cost 160€ white tax.

If it’s all keys list with alarm active you need new bcm.
