I am in the process of working through my first Pro-Tune and the tuner has asked if there is any way that I can have my ROM updated; something to do with Engine Logic (which I am unsure of exactly what that is). Is this a totally necessary job and, what benefits would I get from doing it? I don't doubt what the tuner says, I just want to learn a little more about it.

I have a 2008 car with I860S and I believe that if I was to update the ROM at a dealer this would raise it to the latest version, I8A0S, right?
Problem is, the dealer wants many $$$$ to do this as you might imagine.

Are there any other ways to update the ROM if this is required, avoiding robbery by BMW?

Pm Wedge performance.

He provided the steps for me to update from I860s to I8A0s.

Relatively easy process, crucial part would be seting up the software and cable properly.

Which software and cable is required? Any benfit from updating for you?

Thanks by the way

Winkfp program and the BMW inpa k + d can cable.
Do a search for numerous options.
Updating the ROM allowed me more options for OTS tunes.
