Flash m3.8.3

**sato-bmw** · 31st March, 2012, 02:03 PM

Hi, anyone knows the procedure to flash the ecu m3.8.3 of a3 without desoldering flash eprom? I read on the web interface can be done with mpps, spi or revo3, but I know the procedure or connections. -

Thanks in advance

Thank you very much friend, this is helpful, you know if it works mpps clone?

You can only write files with mpps, it wont read the file, so you will need to find your original file or remove the 29f200xx flash and use programmer to read

If ok, the idea is to read the file orig, and programming via flash are experimenting with different chips tuning

sorry for my English

you have to give pin 43 (shows on mpps window check if is correct pin) on ecu 12v power for mpps to show soft version or write a file ... this way you tried wont work
