Hi guys i am trying to get the file of my seat ibiza mqb 1.8 tsi 2016 engine. Any ideas? Its ecu tuned but i want to add more fuel to higher rpms and i wanna get the file

I am working off of this doc:
https://developer.android.com/training/cars/testing/dhu

It was mostly straightforward to connect using the steps for ADB but this seems overly cumbersome for my intended plans (have to 1. start head unit server on the phone, 2. forward 5277 on the PC, 3. start desktop-head-unit on the PC).

By comparison, Accessory Mode sounds really easy and involves just starting desktop-head-unit --usb on the PC and then plugging the phone in. That's it. Only I always get the message that no ready device can be found.

Googling has gotten me absolutely nowhere. Seems like it's a relatively newer option as most threads involve troubleshooting abd.

Does anyone have any pointers for how to resolve?

Guys, I've read good things in Reddit about MHH Auto, but I can't manage to find a diagnostic software. The website is a hell for me and no one helps. There are thousands of Threads, but not well ordered. There is not a list of links or whatever for finding your software. I'm lost lol.

I need a car diagnostic software and a tablet. Someone has to give links for software, tablet and ODB. Or at least there should be some way to achieve this, right?

Do you have experience with MHH Auto?

Hi friends, I share with you how my small project is going, rn I can't do a lot of testing so I am trying to improve the code. I am kinda new with coding and all, I just created the repo too. If anyone can advice me on anything I would really appreciate it.

Part of the code is in spanish, but if there is any questions I will answer them asap. Thank you!

Hey everyone,

I’m looking for some guidance on flashing my 2003 Mercedes E200 CDI (OM646, CR3, 90 kW, 270 Nm) to the E220 CDI specs (150 PS, 340 Nm, 110 kW). I have the following tools and resources at hand:

• Vediamo
• Xentry
• OpenPort interface
• All the necessary CFF files for the CR3 engine ECU

The ECU hardware number is 646 153 43 79. As far as I’m aware, the E200 CDI and E220 CDI share the same hardware, with the difference being in the software. My issue is that I’m not sure which CFF file(s) to use to complete the flash. I’ve done some research and believe this can be done through Vediamo, but I’m still unclear on the exact steps.

If anyone here has experience with this or can point me in the right direction, I’d really appreciate it. Specifically, I’d like to know:

1. How to confirm the correct CFF files to use for the E220 CDI software.
2. The process for flashing the ECU using Vediamo or if there’s a better tool/method for this specific task.

Thanks in advance for your help!

For years Torque Pro has been widely used by many to scan codes, display data, log it, and plot it. I used to have a car that used a Cobb tuner to load a tune, but then acted as a great dashboard to watch live data. Many people leave their "tuner" plugged in to view live data, largely surrounding engine performance.

I wonder if a dedicated device, that only runs this one android app, and communicates with the car using a USB interface to OBD, would be possible. The obd plug would also provide power to the device so it's a one wire solution.

The reason I suggest torque is because if its wide PID support. So many people across so many makes and models have discovered custom parameters inside torque that can display very specific data from their car, over what a standard scanner might read.

Think it's worth digging into?

Been buying a few cars as of late to hack. Any recommendations on Best OBD bidirectional around $1000 budget. my car are between 2019-2024

Toyota, Tesla, Mercedes

Autel, Ancel, Topdon I am looking at.

Only one I ever used is Innova basic obd scanner.

Fairly tech & Tool savvy. I am an IOS Dev & worked in IT at Broadcom & Microsoft

Still a noob at car hacking but I did manage to add a karaoke systems to my Toyota Sienna.

I am currently working on a project of lockbox that has cellular service for car rental.

I need an OBD scanner with special function to disable and enable features. Specifically Telematics.

Thanks

I need to swap a module and I would need the donors EEPROM to be wiped and ready for me to use my diagtool to swap VINs. Anyone have a reccomendation? Or hell, I could do it myself if you showed me some good tutorials and the hardware/software to buy

I upgraded clusters on both of my vehicles, but now I have incorrect odometer readings becuase the milage is stored in each cluster and not the actual computer of car.

Hey everyone,

I just joined the subreddit, seems like there are quite a few useful topics addressed here. Going to the question:

I want to be able to read the oil Temperature of my car the same way as I can read the rest of the live data(RPM, Coolant Temperature, Battery Voltage...) in an OBD app like Torque Pro or something else. The car is a 2005 Mercedes W203 C180 Kompressor. The PID for oil temperature is not a standard one through OBD but I found it in RandAsh's repository(https://github.com/rnd-ash/W203-canbus), if I am correct it should be this one:

ECU NAME: MS_308h, ID: 0x0308. MSG COUNT: 27

...

MSG NAME: T_OEL - oil temperature, OFFSET 40, LENGTH 8

and If I interpreted it correctly this means that I should look for ECU with ID 0x0308 and then take the bits from 40 to 47 or the 6th byte of the response that comes from that ECU. Also if I understand it correctly MS in the ECU name refers to the fact that this device is on medium speed CAN network.

So first I tried with a vGate iCar Pro 2S to just put the ECU ID into the custom PID function of the TorquePro app and as equation I was taking "F-40". It was not working as expected, because just the response from requesting ECU ID 0x0308 was 5 hexadecimal symbols which I suppose means something like 2.5 bytes which did not make sense. I realized that the vGate iCar Pro 2S does not support MS-Can.

So I bought a vGate vLinker MS which is supposed to support MS-Can and tried the same thing. It did not work again, this time it gave a 6-hexadecimal symbol output which is still less than the total length of messages that this ECU has according to RandAsh's findings(which I fully trust).

I tried also with CarScanner but then there was no output when I requested ECU ID 0x0308. When I looked through both apps, the apps were not seeing any other ECUs than the Engine so I think right now that it is for sure some kind of communication problem but I don't know where. I am hoping to get some opinions that can point me in the right direction.

Hi friends, I am wondering if there is a PID that gives you a unique id for a car. I named the post AT command trouble because I am trying to use "AT@2" to get the device identifier, but it has never worked for me. This is where I get the AT commands I am using. I only use "ATE0" to turn off echo and it works.

I am doing a scanner with micropython, an esp32 and a elm327, I will upload my code in the future if someone is interested.

Hi, I need to deal with a broken key fob.

The key fob of Dacia Duster 11’ was wet and after drying it stopped opening doors remotely so I ordered a replacement.

Thing is the common way of programming the fob haven’t worked - ignition on, pressed and held lock, ignition off x3.

Is the procedure different for this brand or the original fob must work to program the new one (which isnt)?

Hey guys,

Recently I've discovered a problem with heavy machinery/tractors - some of them have fuel level data in CAN-BUS by J1939 standard, some don't.

For example John Deere sends fuel level in % under CANID 18FEFCxx

Ponsse has all key data in J1939, except the fuel level - RPM/Engine hours/Total fuel consumption etc.

Could it be that the fuel level data is under non-standard CANID's?

Or could it be that the fuel data is not being sent through CAN at all?

Hi all so I was watching one of “urpi” YouTube videos about mini digital dashes and I was wondering what would be the possibility of getting that to work with an OBD1 car, from what I’ve read in the forum it’s not impossible and I wouldn’t want it to read speed or rpm but rather oil temp, coolant temp and other similiar values. This would be a small display around 4 inches and would simply read these values from aftermarket sensors that will be installed (oil temp and coolant temp etc). I’m assuming the sensors would have to lead to a raspberry pi and from then breakdown that information and input it into the display but if someone could help me further understanding that part exactly and push me in the right direction of what to look at and read that would be magnificent!! Thank you!

I have a Mercedes E class 2017 and I’m looking at this screen. I’m wondering if it will be a simple plug and play install or if coding would be required.

I have attached photos of both old and new screens. Thanks guys

I keep getting an alert on my dashboard to tell me my trunk/boot is open, yet it’s closed and fully functional. I’ve checked all wiring and everything is in order. Is there a way to code out the warning light using ncs expert? I’ve been able to code out light warning in the past but not sure about boot warning. Does anybody know which module/ where to find this option BMW E90 2008

Hi guys I’m trying to use an mcp2515 to read standard data (I.e engine speed, coolant temp) from the obd2 port. The car is a 2001 opel/vauxhall/GM which doesn’t have the CAN H and CAN L at pins 6 and 14 like I have found online. I am using an arduino right now and later an STM32 chip. Could you give me some pointers to how I could get this data from the obd2? Why doesn’t it have CAN H and CAN L? I have read that modern vehicles do not expose their CANbus anymore so do I have to use K Line?
Thanks

Im new to this sub and a beginner to all this. I want to rebuild a transmission for my truck or swap it with a remanned one, any help with reprogramming the TCU??

I am lacking some knowledge regarding the purpose of VAM. Is it supposed to provide some information regarding the connection settings between the server and client (addresses)?

I captured the traffic on my car and the VAM (over HSFZ) looks almost like in https://munich.dissec.to/kb/_images/2021-10-05-133210_751x778_scrot.png

(the only difference is the VIN and MAC address of ECU).

Why is src MAC address provided here? Isn't it enough to have it in the ethernet frame?

At this point (probably due to my limited knowledge) the only valuable information that I can obtain is the src IP (is it gateway btw?) that I can utilize for further communication.

But now comes another unknown part. Based on https://munich.dissec.to/kb/_images/hsfz.png

the client has to assign src and dst addresses, how does one know what those addresses should be?

Both my capture and the linked page are using src =0xf4, so probably this is fixed?

On the other hand, dst varies. Are there multiple ECUs that are queried directly and not via Gateway?

Does a client obtain the list of available ECUs by doing such scan https://munich.dissec.to/kb/chapters/doip/doip.html#iterate-through-all-ecus-behind-a-gateway

How is DoIP different than HSFZ in that regard? Is it possible in the case of DoIP to parse a VAM message to obtain those connection settings?

I appreciate any help and sources where I can familiarize myself more with those topics.

I Tried installing in my car I used the latest version from http://github.com/olli991/mib-std2-pq-zr-toolbox

It looked to be installing it rebooted a couple of times then stayed like this.

It won't do anything else even if you reboot it.

It won't even power off now.

Any ideas or suggestions on how to recover it

Hello guys, is there a way to hack the Launch Creader firmware to add new vehicles? I have the Launch Creader Elite 2, which currently supports VW and Mercedes, but I want to add Mitsubishi and Renault. Is this possible?
