then well go down a bit more in detail, talking about the map informed, then this is gold, I'm doing a bit of accounts, the only way we have to know the length angular dell inj, and then indicatively, the advance to give and starting with the prex rail and calculate calmly through the times inj and turns the duration in degrees, I'm armed with a pen and paper and I have come to a concusione correct me if I'm wrong, the 1.9 16V E4, basic and very late from 1250 to 3000 rpm all the iq and anticipatissimo from 3000 up with the low iq and early enough for the average-to-high iq, reasoning and technical-practical I think it's been done for noise reduction and abatement of nox during the combustion, of course, to get something more you can anticipate at the bottom, by my calculations you have done (more or less accurate, I think) we have an average of 4-5 degrees of post inj to in the region 1250-3000 (and in some cases 7) and then let's say 10 degrees of advance for the low iq to rev higher and a couple of degrees for iq higher, correct??
