Info :For correct operation device it is necessary to change CID SDcard on 035344535330344780399b1368010300.

This procedure is supported by not each SD card.

Programs for change of CID and the description of process easy to find in the Internet.I used mmc32 and evoplus_cid from github. This programs for linux. I haven’t found soft working in Windows.

It is difficult to find SDcard which supports change CID.SDcards with built-in chipset of production Samsung meet such requirements….or buy on Alibaba, using search “CUSTOM CID”.

-Cables to wire up to the DME

Software setup:
The instructions provided recommend the use of WinXP/Win7, disabling all network connections and malware detection programs. I was in a rush to stage the software and connect the flashing tool to ensure all was OK so I tested the following setup on a Win10Pro x64 machine. I also made the changes below before starting:
-Disable Driver Signature Enforcement – REQUIRED or Dimsport driver will not install and device will show as ‘Unknown’ under Device Manager
-Disable AV/Malware Software – I use Webroot/Defender and shut them off
-Disable LAN/WLAN adapters

After making the changes above to my PC I powered up the adapter and plugged in the USB cable. Windows warned me of the unsigned driver and continued the install.

Bringing up Car Diagnostic Tool KTM100 I see all is recognized correctly. You can also see below that the DME is supported and a plugin is available to communicate with that DME and calculate the correct checksum. Ready to start!

On Sunday I was able to get the car on the dyno and grab some factory numbers.

Phase 1 – Reading the DME:

Here she is. Bosch MEVD172G DME.

Below are a few pictures of the outside of the unit. I cleaned up a bit of sand around the unit to make sure nothing gets in while I attempt to open it up.

After about 30 minutes with a small blade going around the edges of the unit I was able to open the casing up. Luckily the components are not close to the edge of the case so as you’re going around it with a blade you don’t have to worry too much. But as always be careful not to jam the blade too deep; you may accidentally damage some of the surface mounted components.

Wired up the unit to the ECU Programming Tool KTM100 clone using the PDF attachment I posted earlier. Reading procedure is as follows:

1. Connect wires from the provided harnesses to the DME pins as shown in the Bosch PDF including BOOT pin.
2. Power ON KTM100 and connect to USB on PC
3. Launch KTM100 Application
4. Connect the harness side of the cables to the KTM100
5. Click ‘ID’ in KTM100 Application to verify DME communication.
6. Done. Now you can carry out the function you need (read/write/etc)

Phase 2 – Tuning:

You have two options:

1. Acquire and LEARN tuning software like WinOLS, ECM TITANIUM or similar, and spend time and resources on custom dyno tuning the car.

2. Take your dumped files and send them off to a tuner for tuning service. Most US tuners will flat out turn your business away. I wont call them out here but I would encourage you to contact them and listen to their response first hand.

I installed the DME back into the car yesterday afternoon. It was pretty nerve wrecking to sit in the car and push the ‘Start’ button. I was very confident I followed all the right steps but there’s always that sense of uncertainty in the back of your mind. What if i damaged something? At that moment I didn’t care if the remaps actually yielded any results; I was just hoping the car would crank back up. I held my breath, pushed ‘Start’ and the car sprung back to life. It was such a sense of accomplishment.
