YH35XX Programmer & Simulator reading and writing 35128WT

YH35XX Programmer & Simulator can be used for reading and writing 35128WT. Easy to use, no risk and no red dot on odometer. Here shares how to change mileage for 35128WT with YH35XX Programmer & Simulator.

You need:

1 pc x PC

1 pc x YH35XX Programmer 

1pc x Simulator

Steps to change mileage with YH35XX Programmer & Simulator

Step 1: Connect YH35XX programmer to PC

1.Remove the original 35XX EEPROM from the odometer and solder it to the adaptor board

Then clamp the adaptor board with the solder-free clamp

Make sure the direction of the adaptor board and solder-free clamp is correct

2.Plug the YH35XX programmer into the USB port of the PC

Click "computer" and it will recognize a usb flash drive named 35XX programmer

3.Click U disk 35XXprogrammer

Double-click "BMW_ODO_Standard_edition. exe" to open the software

4.Wait for the prompt: Programmer connect successfully

Then run it

Step 2: Read and Write EEPROM Data

5.Select the EEPROM model and click "Read DATA+ID"

Check whether the read mileage is the same as the actual mileage

6.Click "Save Data File"

Save the original data of original EEPROM to the folder

7.Hold the handle of the simulator

Clamp the Simulator with the solder-free clamp

Note: Pay attention to the direction

Then connect the solder-free clamp to the programmer

Connect the programmer to the PC


8.Select EEPROM model

Click "Load Data File"

Select the corresponding data of original EEPROM and load it

Check whether the displayed mileage is the same as the mileage displayed in odometer

9.Once the mileage is confirmed

Click "Write DATA+ID"

Write the original data into the Simulator

10.Click "Read Data+ID"

Read the data written into the Simulator

And check the mileage

Step 3: Change 35128WT mileage

11.After the mileage is confirmed

Click "Mileage modification" and input the mileage you want

12.After confirm the input mileage is correct

Click "Write DATA+ID" to write the modified data into the Simulator

13.After the data is written

Click "Read DATA+ID" to check whether the mileage modification is correct

14.If the displayed mileage is the same as what you want, cut off the handle of the Simulator, and solder the Simulator to the original EEPROM position. Pay attention to the EEPROM direction. Install the odometer back to the car to verify whether the mileage modification is successful.

Get to know VCM2 different color PCB

The VCM2 quality is not a matter of PCB colour, but lots of people wanna know more.

Here's something from pros (dstirrup and MrPhil)
I just wanted to comment on the issue of the VCM 2 PCB plating as I am qualified (electronics and computing).

The boards are made of copper laminated to fiberglass. When these boards are made - BEFORE installing the electronic components - they normally plate the copper with tin or a cadmium alloy to prevent corrosion of the copper.

The colours you see are a consequence of the plating process.
- Tin is a silver colour and has been incorrectly described early in this thread as Aluminium which is never used for a PCB plating. Tin is the normal plating used as the solder is an alloy of >90% tin. The old 60% lead and 40% tin solder is no longer used as the lead is a poison that leaches into the ground when electronics are disposed of.

- Gold colour is the cadmium alloy plating and is usually selectively applied where exposure to moisture occurs such as connector contacts and test points. I rarely see it soley used on the whole PCB as a plating but it can be cheaper to plate the whole board rather than selectively at times.

- The real Copper colour of a red gold is an unplated board - VERY BAD. I would avoid such a unit at all costs because if they are such cheapskates and cost cutters not to have the PCB tin plated then they will have cut costs elsewhere.

There was a reply that tried to correct this matter but I hope this makes things a lot easier to understand.

BTW, There are many other issues that affect the quality of performance of any electronics such as capacitor quality.

This is for your information!

If the board is showing all the copper tracks then that is a problem in itself which leads to oxidisation in air, most boards have a coating (conformal) to prevent this, finding a pcb manufacturer who plates every single track is impossible, coating the pcb with a protective layer of conformal prevents oxidisation in air and compared to the cost of tin varnish is minimal and the process much cheaper, tin needs high temperature to flow while varnish can be sprayed on at room temperature.

This is good info to know…

But actually…. I still think the problem we all face when we try to do certain functions is due to poor quality components (or missing components)

My vcm2 sp177-c1 works perfectly on ALL new generation ford / Mazda but have difficulty to achieve some functionality on old ford based ECU (also on Mazda equipped with ford ECU).

I’m pretty sure that the Chinese “engineers” who developed those clones didn’t copy the OEM board 100% . They must have took some shortcuts to save $$.
