2009 C63 AMG
I figure I share this with everyone as I watched the guys at Powerchip flash a member's ECU on a C63. Basically he takes the thermal cover off the ECU to expose the board which is filled with IC's (Integrated Circuits) on the lamina. It seems they came up with a device that is able to probe on to an EPROM chip so it they can write code to it. I couldn't tell if they were also changing any VHDL code in the FPGA's on the board but I doubt they did. With the use of a lap top with a code program ( I don't think it was C++, all I can remember is seeing a bunch of hex numbers, sorry I'm not a software guy) that runs a USB/Firewire connection out the back that goes to a transceiver which switches to a serial port that is connected to a pin strip that connects to the probes (which are really more like pins to piggy back on the EPROM). Of course for all this to happen the tuner needed a 5V power supply which he connected to one of the pins on the main ECU connector along with the corresponding ground. I'm not sure how he knew which pins were power and which were ground with out a schematic of the ECU. Again this is just from a hardware standpoint. Everyone obviously knows the crux of tuning the ECU is all software.

As posted in another thread:
Another tune out there. I wonder if they had a peek at an E63 map or are copying other tuner files? I thought I read from Jeffield in the Vancouver thread about PC having a 80/80 tune done on a dyno?

Found something similar to what you are describing. You buy a BDM100 unit that connects up the the ECU and connect via USB to your computer and use their software to write to the ECU.

That is VERY similar to the BDM they were using. I guess they haven't cracked the ability to read/write from the I/O pins on the top connectors.

The BS and E uses the same exhaust manifold, but terminate into 2.75" pipes. I was hoping there were more similarities. Thanks Jim!

Don't know how much of this is true or BS. Look at Post #101 in this old JRCart thread:

The software is then sold, its up to the individual tuners that buy the software to change and modify the software
I am not pointing fingers at powerchip or MHP but this might of happen due to the fact that they bought the same software and never modified the orginal tune.

Going slightly OT on my own topic here. Stumbled onto this site that sells a BDM software and hardware for ECU tuning. I wonder with these tools, can we reflash our own ECUs (using tunes we bought) after the dealer flashes them so we don't have to send our ECUs back to the tuner?
Hardware (ME9.7 supported): http://www.cmdtec.it/prod_EDC16.asp
Tuning software: http://www.cmdtec.it/prod_map3d2007.asp
Download the manuals for interesting reading.
Here is a Made in China programmer (must be cheaper) that supports the ME9.7: http://www.made-in-china.com/showroo...V1251-Set.html
EDIT:
I didn't even realize Shoof was onto something until today.

According to the first post on the topic "P30 Discontinued" the tunes seem to be hardware. If any software was involved I'm sure the K1 you have would've already included what was done and exceeded what would be done on the P31.

I know K1 would have exceeded P31 software. I just wondered since the ECU is the same, the dealer might possibly flash P31 tune for non P31 cars. I thought the changes in the hardware (crank, conn rods, pistons) didn't make power? Would be cool if someone knows someone at the dealer and have it done for free.

They are both ME 9.7 ECUs but they have different hardware and software numbers, and due to this the files are not simply interchangeable. Each tune must be written for the specific hardware/software #. Therefore it is not possible to take a E63 "file" and just place it onto a C63. It is an entirely new remap of the ECU.
And in regards to the Renntech Brick, I believe that it is necessary to send the ECU first out to Renntech in where they will modify the ME9.7 ECU to be able to work with the brick, so technically speaking, yes, it would be possible to do it to a C63 ECU. The RAT (Renntech auto tuner) is not possible to be in use with the ME9.7 ECU, and therefore cannot be used with the C63.
Hope this helps

The AMG 63s use a common ME97 ECU platform. At one time, all chassis used the same firmware so the same firmware base worked on the C, E and S. The firmware contains map sets for all chassis with the set being chosen by variant coding.
With respect to the programmer, there is a version of the OBDii programmer that will do the ME97s in the AMG 63s. The only caveat is that the ECU must visit the tuner once to enable this feature in the ECU. Once enabled, the end customer can switch between different tunes (or stock) in under a minute. The programmer can also be configured to log data
Lastly, please note that Renntech is no longer an authorized distributor for the programmer and can not supply beyond what they currently have in inventory.

As far as doing your own flashing, there are ways to work with a tuner and have your own "slave" equipment (BDM) to program the tuner's encrypted files. Most BDM systems will honor tuner markings designed to prevent their calibrations from being copied.
With respect to buying BDM equipment and reading raw stock binary data from the ECU, you can do this as well but you will be presented with two megabytes of raw binary data to decipher. The program EVC offers for doing this type of work has a very steep learning curve and is not for the faint of heart (although a lot of fun if you’re a nerd like me
)

Please remember that the ECU must go to the tuner once before the programmer can be used. Once the ECU is enabled for programming, you can swap tunes on the ME97 in under a minute.

So are you saying that this hand-held tuner that Renntech and Brabus has is available to the public to purchase and for those of us that have been tuned, we can load our tuned file (in my case Kleemann) back into the ECU if the dealer reflashed them?
