change advances

[savek]

on the new multiair what do you think of the advance?

[max boost]

I will quoto emilground , even if I don't ? a crime, not even on the maps pi? quiet you can? change that by increasing the amount? injected you alluga the time to inietttare of pi?. Concretely speaking to? in the absence of smoke, and no view of the complexity? the correct calculation makes me quote the first post msport on standard maps do not need to complicate your life

[faberecu]

you are sorry .... but the tour what it says... + or - advances the useful result to ****llo-power ... , if we can burn them all without creating excessive temperatures and pressure spikes dangerous for the manovellismi , I say we are ok
but we can with the engine closed to verify ... or we need to do a test to destruction to find out for sure?

I personally maps thrusts use 45 points at full load 4000 rpm , it seems to me to work better , I can post the differences in power next week with advances ori and mod

I'll post my solution:

I personally having an engine 1.9 jtdm from 120 hp and 8v we have studied above, and after various tests between smoke; hence, and tour braked I conlcuso that the advance for what regards my engine must be given so as not to exceed 8-9 degrees post pms that fall down to 7-6 for a high rpm, and, indeed, the original map advances to 4500 does finish the injection right in the pms, this is due to their alf act that 4000/4500 rpm the motion of the piston ? very fast and it takes some time to detonate the fuel.

Having said this I what I do: increase the rail usually on maps driven by the 1600 bar the original as closely as arrival also 1720bar at high rpm is usually not more for ncercare to minimize the time of niezione to a high rpm, the increase of 150bar-to-medium speed (e.g. 2500-3000 rpm), then I make the break for the quantity fi diesel that I want to inject, then me the calculation, around you will find a sheet in exel from me posted on how to calculate perfectly time inj engines jtdm, once this is done, I have prepared a sheet exel where I calculation for each number of revolutions of the injection time used in base pressure at that rpm and tinj for that quantity of diesel fuel required-pressure, once this is done the turn in degrees using the formula ((60sec/rpm)/360?)x1000000(usecondi) and I find the time it takes the piston to a degree, (let's leave out that the piston does not go to the speed adjust but effettivamento slows to a stop in the etremita but for the calculation of our advances ? irrelevant), and knowing when to lasts a degree, we divide the onstro time inj for that degree and find how long is the degrees that injection, then subtract the injection time of the advance pretabilito and see if you need to change the advance. this ? my method

I personally do not edit almost never advances, however,' if I make a map thrust,I feel the car and I see that smoke,in the laps in which to smoke, do 1 degree of advance,if you smoke still do 2,the maximum cmq 3 degrees and I stop,usually to fix and the car is fine...

anyway, I wanted to have advice with regard to the advances of the gasoline car,does anyone know how they work?

[tidus1985]

are never excessive if you need to end the injection in the right spot, obvious, and the good does not exceed a certain threshold, if you see we have advances up to 21 degrees on a jtd, I have found the machine that murava to the 27? then what ? limit, then you have to see if and how many do you need, do not give them to the hell

[jovandj]

I call them what you will, according to me, 0,5, 1 degree on the 3500-4000 to have a bit of aggression in the more we are

[Emanu88]

I agree with msport on maps with increases in relatively low they should be touching them, I know a prepratore that map so heavy many mjet with 2256 and 2260 vk and is located to inject the quantity of galosio important change, and I must say that the feel of running those engines seem to turbo petrol change their own sound and longer until limitaore and with egt in accordance with

[marbis80]

From the various tests that I'm doing on my machine, I can say that I have noticed that with the injection times are very long the car smokes a lot and pushes, however, a lot, with the same times by increasing the advance payments, the machine stops or almost smoking and the output becomes ir? sweet and simple, but at the same time I feel less aggressivit? in riaccelerazioni. These are just feelings we would like the numbers to evaluate the thing, but anyway I don't think it is wrong to edit them, of course, it would be appropriate to at least use the "method of tidus" the cio? calculate what they really need, and never exceed a certain num of degrees of post-injection.

[jovandj]

I try to spegarti and explain why anticipating the end of the injection ends before (obviously) so do not throw fuel or throw much less after the pms...of course l delivery softens and can burn more diesel, but in the next cycle you have less exhaust gas you are loading the turbine and here is why? feel the machine less responsive...lengthen the time and a simple way to increase the classical flow of diesel pero extending the time automatically postpone the end of injection, and you're forced to anticipate in order to avoid the smoke...and as a covered short if you cover above, you'll find out the feet ditto to the contrary.
The ideal would be to find the right compromise between the time-advance, and the method of final fantasy x, and really useful, in fact, I thank him, I am about l to increase or modify the advance: if the times are not changed too much, you can also jon tap advances, but if you to stretch much you're forced to avoid the smoke and have a better combustion and of course a total return best
