smart 451 reprogram of ecu

[dimosbmw]

Hi DK friends.. I need some help about my smart 451 84hp. Does anyone know how can i reprogram my ecu?? What kind of interface i need and what software. Need to open the ecu or can i do it directly from diagnose socket or ecu socket?? And finally does anybody knows how to kill the speed limiter?? Please be specific cause i am noob. xD
Thanks in advance!

Hi
I suppose you are talking about the 1.0 turbo engine ......
Therefore, in this case, what do you hard, you need a professional interface, cmd, kess, etc.. and open the ecu to read / write on boot-mode

well you could use a less expensive tool like
galletto but i think you would still have to open the ecu to put it in boot mode
the best would be for you to just use a eprom programmer
and do it out side the ecu itself
