sorry I see evil but, according to me, should be redone all from****.

why? you say cosOriginally Written by marco
thank you for your assistance fundamental, could you explain why do you not go or how would you do it yourself?
hyrosat follow the advice given by Sandro and don't worry about those negative comments without motivating them...
A further advice I can give you ? to adjust the injection timing on the basis of the required torque.
I see that on the map the pedal request up to approximately 450 nm of torque which are required about 100mm3 of fuel (as you can see from the map amount? fuel as a function of RPM/ torque)
from the map times as you can see, the bp up to 80mm3 then it would be appropriate to calculate the time to get up to 100mm3... you can work on the last 2 bp, for example bringing out the 60 70 and 80 100. (parts from a higher pressure to 600bar)
Did we? don't forget to adjust the limiters of fuel as you suggested Sandro.
why? you've changed the map a couple during the start-up in that way?
the map serves to solve the problem of hot start and cold-or am I wrong? you, how would you have done now about the best
ok the functionality? ? exactly that....
- how have you changed yourself? not much sense in order to solve the problem of departures difficult since? the problem is the lack of torque in that instant where the motor is made to turn the starter, and then before you even get fully operational 850/900 rpm.
you have problems with cold starts I guess true?
on the basis of the experience made on my on intuition, I would say to increase in the range between -20 and +20 ? C, from 100 to 850/900 RPM, as increases from a 10% hard to start.
Once you have made the change to make the tests of cold ignition at different temperatures and see if the problem ? still present, if so you are going to retouch only in the range of temperatures where the problem is ? still present.
Then if you want something already? tested on my with problem solved 100% I send you a screenshot of the increments.
this problem of cold starts and even warm wrapped up already? ? true now that I think I have to have pi? torque before the engine enters the operating regimepardon small inattention
if you want to send me the screen I give him a look gladly thanks
I was also trying to understand the timing of injectioncould you give me some more input
for injection times you can work on the last two columns, as you mentioned, and transform the 60 70 and 80 100.
To calculate it, there are different methods some more? accurate than the other but they require different calculations.
I personally do so? and I find it very good:
calculating the difference between the times of the 80 and 60, and I know that that difference is added to the column of the 80 gives me the values for the 100, to calculate the 70 high 60 mid? of that difference.
Keep in mind that this is my method allows you to calculate the time with a certain approximation, but considering that a +/- 3% error does not affect the result so for me are more? that is acceptable.
There are other users that have done a great job on (Tidus1985), obtaining values much more? accurate but require much more? work.
I'll explain in broad lines why? my method does not ? precise:
Firstly, you should consider that the injector has a time in the uS that need to open before you actually brew fuel, time which varies as a function of pressure, so you should go and calculate for each step of pressure, what is it ? the opening time of the injector, did we? calculate time in this way:
T100= T80 + (T80 - Tapertura_inj) - (T60 - Tapertura_inj)
At this point we are going to have more time? precise, even if in reality? there are still other factors that affect how, for example, the operating temperature of the injectors themselves.
If you want to look at the discussion started by Tidus to rigurardo, treats the topic more? in-depth, note that if you decide to use this method you will need to ricalcolarti you the opening times since? the ones calculated by Tidus are not suitable for the injectors of the 159 (gi? occurred).
I managed to make some other edit to my map, as always, criticism and advice are welcome
