change advances

[cicciogsr]

you could make a proportion with the original values once you have assessed the maximum flow rate ... I think I understand that you know well pumps and injectors then I think you know what'? the limit of the injectors of the car and its pump pretend that you want to inject the deal? the maximum to which you can? get do you calculate the advance while maintaining a performance similar to the original... test on any commonrail and tell me what you have... if the ori ecu injects, for example, 70 mm^3, with an advance of 20? made the account how far in advance we want to inettare the maximum possible... I want to reiterate that we are tying injection time and advance... we're not pulling in dance and other things..

no jack I don't follow...if you do not know how long the injection how do you calculate how long it needs to stay open the injector to inject 70mm3 knowing that the injection part 20? before tdc??
can post some formula if you want??
then I really do not know the flow rates of the pump and the injectors of the car and of the common rail.

[cicciogsr]

the formula is ready there will not be d? why? then end the discussion without posting results of tests and why? according to me ? too ridutiva and not very effective ... instead of reasoned alone.. I have already? written all over and I think I was clear..

[cicciogsr]

what car do you have?

[cicciogsr]

if ? a common rail try to mod the advance, as I said, in proportion to the iq that you want to achieve, following the logic of the ecu and post the results of your tests also accompanied by a log made with the diagnosis...

[munro]

ciccio the fact ? I have not figured out how to moddare the deposit based on the iq....because, however, the advance, and only the point from the beginning of the injection, but doesn't say anything to me, because the one that counts and the duration to inject a certain iq...

[cicciogsr]

here, then, we decide how much fuel to inject change the times and, consequently, the advance, keeping the parallelism with the original, I exposed how I feel now, try to do so, and verification of the diagnosis that the ecu takes the values that you have set.. only cos? you can realize..

[cicciogsr]

if to inject tot diesel it takes certain amount of time, with so many degrees of advance by changing the flow rate you have to adapt to the other in proportion now you have everything in the map golds to get the links..

[munro]

you say you to es divide the 70mm3 for the 20? degrees of advance practically we 70/20=3,5mm3 for instance?that every 3,5mm3 of diesel I have to increase a degree of the advance? on, I believe, you reduce everything to this simple calculation, elementary...

[cicciogsr]

for example, to dispose of 10 mm^3 in ir? in theory you need about 2.5 degrees in pi? in advance. the calculation of v? made for all of the rpm at which you change..
