Actually, it is possible to re-flash the EP-ROM of many injection
calculators, especially those in newer diesel engines ; with
"third-party" code that promise more power. Who knows what is included
in this code !

Most insurers will not cover you if they discover after a crash that
the code was changed ...

That's typically arrogant. There's ample evidence that you often don't
know what you're talking about, but it doesn't stop you. As an example
in a long list of them, you never go further to elucidate your stoopid
musical theories. What's that proverb about he who knows not, yet
doesn't know that he knows not again...

I'm not in any way into IT and computers, but I doubt that the notion
of "operating system" applies for a computer such as those which
control injection.

As far as I know, it's just simple code flashed onto an EP-ROM, in a
binary form. There are no programs to execute or files to read.

As Jim said, there are certainly strong "barriers" to prevent "foreign"
and unwanted code to run and possibly jeopardize the behavior of the
injectors.

Does the notion of a virus apply there ? I'm not sure.

Guess who is responsible ! :-)

Maybe Mxsmanic only drove carburettor cars ?
