Limiter smoke

[panterargento]

A greeting to all,

could someone explain what'? the task of the limiters fumosit??

By changing the map of my car (alfa 159 jtdm 150cv) with ecm titanium I have always ignored, why? looking at some map made by trainers and these are not touched.

Therefore, I do not ask in which way they should be changed, but what they are for.

Thanks

I believe they are also protectors of the deal? diesel fuel, in part to give the ratio BETWEEN air and fuel.
Best wishes to all !!!
