I have a doubt that I can not clarify.

I know that everyone reprograms in their own way.

But how do you modify the common rail maps ?.

Thank you very much

common rail maps can be tuned with diferent ways,tune it only in the areas you need,no tune under 1000 rpm,and remember more rail pressure= less duration for the same IQ,use this to adjust soi in large IQ quanties

Ok, then touching the common rail maps only has the function to decrease the duration and have good SOI and EOI, right?

Improve diesel fuel consumption?

yes,and the car feels more responsive too one

Thanks, very good explanations.
Where are these common rail maps modified?
At maximum rpm and maximum IQ?
