change advances

[cicciogsr]

chapter closed ... they are here to learn from people who have a lot of experience.. my studies now concluded, lead me to analyze problems with an approach perhaps too theoretical and the practical ... my style of response ? just to make people reflect and to stimulate discussion in the to ask questions that can help you think...will change? attitude

I apologize to munro and with all those to whom I could give the impression of lacking respect.

according to my humble opinion, if you make a map soft ok but if you go a little further with the diesel you have to touch them to burn everything and to lower a bit the egt

[mcjtd]

but there is a correct way to change them? or perlo less c'? a calculation that you can? do??I have always wondered how to act listing of resources advances,and for this I wanted to ask you,seen that you talk about it,we put the case we have an injection of 60mm3 of fuel with an injector opening time in microseconds 795us and the advance ori ? to 21? btdc as you f? to know in degrees how long does the injection??and especially if I wanted to increase the injection time of 10% bringing the opening of the injector to 874,5 us to avoid injecting out of time how can I recalculate the advance??

[savek]

if them increases by only 10% l' ecu in automatic autoadatta then anticipates alone

[mcjtd]

not I think

[savek]

if ? a edc16 ago but with the 10% increase on the times I don't think there is a need to anticipate...

[mcjtd]

if you say it
I am, however, a half-idea I made also on the basis of you have injection times and the cio? if at 4000 rpm I have a time of injection
of 795us to know how long the degree opens the injector I do this calculation 4000X360?degrees=1440000 these are the degrees in a minute in a second make? 1440000/60=24000 degrees / second now to find out how many degrees do? the motor according to the injection time lighthouse 24000/795=30? degrees... I say pu? be feasible? I recommend you do not make revenue read, and then do all the omertosi....

[munro]

it might be feasible as a calculation, but this refers to the duration of the injection, not when "part" with this calculation, for example you could calculate when the end of the injection according to time in advance of injection of that?:advance from pms 21? duration 30?> 30-21=9? it could be that the injection ends at 9? degrees after tdc...? what to expect, say those who have studied..and I am referring especially to cicciogsr and chris156...I'm curious to hear what people have to say...

[cicciogsr]

I time ago I built a table that roughly allowed me to evaluate both the duration and angle in the beginning to dispose of the whole capacity after several measurements, I realized that the values were not the measured values... and then ? good to start from a log ori, to understand which values in the tables are significant for the change... after you set the iq that you want to inject and you calculate how much before tdc you need to start injecting goes well the method posted before ... I, personally, for the type of map that I like to do is not advance a damn thing why? I try to take advantage of the post injection to decrease the transient and do not have high pressures in the room.. for the rest, each person has his own method and from my experience the mod of advance payments for standard maps under 30 hp do not serve, indeed, create problems at full load ... this ? my opinion..
