Increase injection Times: YES, NO, MAYBE

[tidus1985]

be my ? a calculation is a bit spartan, but it should work logically, for the injectors risks of stararli to pen pressure above 100 bar and more, you're the quiet, regarding your machine, I'm still a beginner I don't know if I would be able to interpret a edc17

[SandroMarciano]

Not the stara nothing... Around with 1650 bar on a JTD born in 1350 and is not ? still nothing exploded ... People that I know runs with 1700 bar and the injectors of the series, the only contraindication pu? be the spray altered..

Feel sandro, about the timing of injection misono noticed on my car 147 mjet 120cv that even raising them if I'm not going to act on the map ", the quantity of fuel injected" I did not increases tangili, otherwise if moddo this mmappa in relation to the request from the map wish, I noticed tonight. Correct me if ? a error!

I the injection times almost always change them to the low numbers of laps to get a lively engine and as the revs rise, i leave time
the same, I think we all know that an engine is too early to high engine speeds walls.
but on the multijet ? much more difficult why? c'? a single map

Post an example of what you say on the mjet I'm following the timing on some of the mjet I know, or more of a

sorry, I was speaking of the 1.3 multijet, map "injection, split" ? really? the duration of the injection time and ? the only addition to
"injection zoned map 1" that should be the rail pressure

Anyway, I don't understand how the increase of time of injection causes an increase of the advance...

[dariuccio]

In parit? pressure (rail) to inject more fuel, the injector must remain open for more time, therefore the ecu anticipates the opening of the injector

The change of the timing of injection, and a very particular if you do not know what you are doing you are likely to do damage because if you increase the injection time so disproportionate you are likely to give diesel out of phase and this is not good for the engine bottle that promote detonation.
I personally change them and the difference you see then let each of us has his theories on it or not

Excuse, the question that may be stupid, but what ? the detonation (I hope that does not burst anything), what damage could bring, and as you realize that this happens?
