time inj does not have a performance "adjust" in quantity, but they have the technical timing of the opening pin which depend in particular on the rail pressure, then the opening time of the needle always remains the same and the more it stays open the more amount of diesel is injected, then a normal and that employs 1 mm3=207 x 80 to inject 80 mm3, but there put? much less because the needle open only once
The power is nothing without control
But anyway, you don't need to know this to calculate the advance payments you just need the injection time in the map for what to calcolarti the exact time of injection you can do it from a pompista to tour you can go near if I'm not mistaken, and used the formula and charge of the capacitor

However, a principle, you can do it..if you really want to know the micron diesel fuel then you need to proceed differently, and for via test benches....in the late 80 78 82 mm3 do not granch? difference

The advances are changed only on the naturally aspirated engine, the turbo will only change if the car has other issues after having mapped without advance.
Where written this rule??

Quoto. According to me, the change of the advances ? very important both for performance and for fuel consumption. I gave up 3 degrees in some parts of the 'load paralyzed' (calculating all with durations of injection, pressure, diesel fuel and engine rpm), and the difference feels right, the throttle response ? pi? responsive and fuel consumption drop of, not a little, especially in the area of 1500 to 2500. At high rpm instead of the down as well a bit with a light load as the injection ends much before tdc in the last curve. This from the original I think is done on purpose to make a quicker cooling of the engine at the time of release, this is I think from the moment that if I let to hit the throttle to 4500 the egt go down immediately, if, however, a 4500 I put in neutral and let off immediately the engine at 850-900 rpm the egt go down more? slowly.Originally Written by jovandj
However, I also reached more than 6 degrees in pi? to 4000 rpm without having the machine walls, speaking also of car with turbo plus, and other components changed. If the diesel fuel is given in abundance, and the advance must be given just as carefully always trying not to inject too much over the pms. The management of the afr has a population of mounts as with a Afr of pi? low " it will speed? the combustion process and then will be? need less advance, and vice versa Afr lean tend to have need? an advance higher because of their speed? combustion is less.
hello
if I can, how high is 1 degree in the map?
excuse the ignorance, as they do at lower temperatures by lowering the advance at high rpm and low load, and, at the time of release, you should not be at zero load?
with regard to the difference of heat exchange between the mad and the release in the rotation you say that ? always a question in advance, or because the motor is in rotation and enters the Cut-Off ?
The temperature drops because? as it says in Engine83 leaving the engine at a high rpm with request 0 the water pump continues to put into circulation the liquidocon a speed? much higher than that if it were in neutral, then we must not forget that the higher the flow rate of air that enters the engine ? higher than the low, also helps to cool.
Advances have nothing to do, even why? in the release, the injection ? 0!
When you start to inject the right amount? substantial from 100mm3 up only 4 degrees, according to me, is not enough.
Personally with 110mm3 use 5 degrees about the 2.0 mjet which has injectors pi? fast.
I, of course, the increments to the advance does not need to be given to cazzum wisdom well as 1 degree can be harmful, personally, after the advice of jack I moddato advances in the regime 1250 3000 2 degrees you will notice the difference, of course, the machine responds better to spool the turbo, which of course go to lose you retrieve the map with the vgt, for example at 4000 I have about 4 degrees to 80mm3 press rail stock to 1600, with even 0.5 degrees of post PMS and the rest before TDC, now I'm trying to remove a little of advance at low rpm with high IQ to get in better spool the turbo you talk about 0.5 degrees, a bit like the 1.9 140cv-e3 2.0 170cv
