It would be nice but IIRC the motorsport ecus are significantly different from the stock ecus.

Also, expensive.

Yes, I found out it was wery expensive :-(

But I have compared the 40CSTX36_ccp_en.a2l with another ME7.5 .A2l of same version, and it mostly looks the same. Same CPU, memory mapping etc.

Would be great if someone with the right skills had a look at this :-)

If you look at the A2l file, there are some very interesting things that other A2l files doesnt have.
Just look at the checksum and communication stuff:

I think this might be possible now.

I have successfully flashed both cpu, eprom and flash.

I have still just done some bench testing of some in and outputs, and all looks good so far.

Since I dont have the Msa-box, I havent got it communicating with the software yet.

I have the driver firmware-files, and it seems to be based on a SAM C21 microcontroller.

Could you remember, or find out what the ecu-difference was?

Update on this :-)

The MS4 ECU is a ME7.1.

With the firmware from Bosch MotorSport it has a little different pinout than Vag.

I have also managed to get a actia xs interface working with software.

Also the file must be modified before flashing to get the right adresses.

Still struggeling with the software, it requires license and pin code.

The software decompiles fine with IDA, but I dont have any assembly experience.

What did you do to get it working?
Modas expects a MSA-Box and I was not able to find any option to configure a different interface.

This is cool stuff! I wonder if you can do some similar things to the ABS-unit?

I never expact anything else. It will be too expensiv to build an individual hardware with all nessessary savety requirements only for a few motorsports tasks..

So they may chance application interface and seed-and-key to differ from stock OEM-ECUs, limit the chanceable maps by A2L and done..

Do you have a A2L for your MS4 ?

If Bosch SW is blocked by licens or PIN, just try to load A2L in INCA or CANape or other and connect via CAN interface to MS4. (CCP-protocol)

Me too, Continetal ABS unit is a OEM derivat, Bosch IMO will do the same

Some flags are directly derived from the installed licenses. But it should be possible to solve it with IDA.

Hi!

Dont know if this has been discussed before, but cannot find much information.

I see that the Bosch MotorSport MS4 is a ME7.5, with the same hardware.

Has any of you looked into if this could be copied/used?

Software Download:

http://www.bosch-motorsport.com/en/de/downloads/software/software_1.html

Bringing this up, do you have any news?

I found out that the MS 3 Sport is a ME7.3.1 like used in my 156 GTA, i downloaded the installation cd from the .jp Bosch Motorsport page,
it includes ModasSport, a workspace and a2l and hex file of the ECU.
Managed to flash the hex file after converting it to bin, and ecu boots up with it, also does a kwp2000 handshake with a diag tool but does not support any diagnostic function over KWP2000.
The A2L file also has the CCP definitions ;-)
Vehicle side connector is pinned out different, Cruise control button is Box speed limiter and stuff, but the electrical levels seem to match (drivers, amperage etc).
Engine side connector is pinned out almost the same.

Regarding the MSA-BOX 2, the Bosch driver is almost the same as the Actia Lite-XS driver, the Actia Basic+ XS is more different.
Lite XS has the same bootloader bin files included.
Modas Sport might even work with the default Actia drivers, i have not tested. Or you could modify the Bosch driver to accept the Actia USB Ids.

Which Actia interface did you use ? A cheap chinese clone ?

Would be cool to get this running or maybe even copy the CCP code to other ME7 ecus, or activate it if its still left in there,
because then you would have a live tuneable ME with a cool gui which parses the a2l files nicely.

Seed DLL is also included for the MS3 firmware.
