Redo the calculation with the factor k with the new Press rail, and you know that time you have to use..
Of course, the tinj with more rail pressure will shorten slightly, and in theory you could use the advances in stock

[giuseppe89]

Excuse the' ignorance munro but the factor K in the calculation, knowing the tiny for a certain pressure right? Calculating the k for a curve of 1600 Bar, and use this k for the iq, which I wish always to the med th pressure...but pressure for which I do not have Tiny in the table? For Example, to 1700 Bar as a calculation the K-factor is not knowing the tiny?I miss this

Munro your message was posted incomplete, are you referring to the formulas that I've posted? also using the reverse formulas I always missing...for calcolarmi the k of a new pressure I would need a tiny reference, and therefore am stuck... if I use the inverse proportion, it is not too rough? the tiny on prex is not a constant

[munro]

Everything is there other formulas there are I if are I are not aware of..varies only the calculation with the rail pressure into the square root you will see that the rise of the Press, there is a shortening of the tinj..
Test of both calculations are for now, do not write anything into the ecu

[giuseppe89]

Maybe there are... then Returning to the example of 70 mm3 to 1600 bar and 923 us of the Tiny me to calculate the k which is equivalent to 527,42.
At this point I do 70 x 527,42 : square root of 1650 = 908 us, and rightly, the time is shortened I believe that finally we have arrived!! There I put a bit too much I admit! is correct then do so?

[munro]

It is one of the correct ways..
In practice, knowing the pressure and time through the constant(K) do you know the new iq..knew this calculate all and simple..

Thank you so much Munro!I was stuck bad on this calculation! But what about the advances it is correct to finish up the injection at Tdc or it is advisable to maintain the degree of post which has been set by the manufacturer?

[munro]

Usually you tend to stay in the "window" injection provided by the manufacturer, because this last one has spent time and resources for that..

EXCEL table !!!!
Trust that stays with you longer drinking it in the table for the start..
