RomRaider

Hello i read ecu file from ecu and i got ms430064 version. i cant find XDF file for that ecu. maybe some1 have and want to share with me Smile?

This isn't a TunerPro software forum. There is a RomRaider xml definition file in the definition sticky.

I know sorry just i think its same here.

I tried open map with bmw ms43 definition What i found there in forum but i got msg "definition not found" or something like that.

Because of only MS430056 are supported here!
I dont know a MS430064 XDF or damos out there.
Downgrade to MS430056 oder upgrade to MS430066.

to write new ms430056 version i have to turn ecu into boot mode right?
can i do it with ecu connected to car just put GDN to PIN and turn keys on ignition? then try to connect by some flasher?

You have to open the ecu an get boot-pin or boot-pin at processor.
Maybe also Kims Tool can flash it, i dont test it.

It does

Forgive me for bringing up an ancient post. So Cloudforce, your are confirming that mss5x can flash in bootmode for downgrading / upgrading software versions?

No need bootmode for downgrade / upgrade.
You can flash Full File (512kb) of Version 56 to it an it will run, done it many times and 99% works.
Only for VIN and ISN... Change (UEFI) you need bootpin.
