A map from "professional" your opinions - Alfa 147 1.9Mjet 120

[peppearci]

Hi guys, here's the map of my car!

I have to say that the map was done by a preparer famous in the north that he worked for a workshop of centrosud, then changed in some parts.

A small briefing before your analysis


Alfa 147
1.9 JtdM 120 HP - Euro 4 without DPF
90,000 km now (original to the car ? was purchased new)
coupons regular
the lower tube ic silicone, higher fascettato
duplex without dbkiller (derivation directly with the diameter of the original)

Problems encountered in the map according to my analysis and my driving impressions:

First of all, I feel a little stretch. In acceleration, the pedal more than 60% (or even before) the sound emitted by the engine changes, becoming more? dark: my impression ? exercise of any limiter and a roar from "a lack of air". The limiters, diesel, etc, etc, I seem to be ok...
Discourse smoke, is known to low and then disappear from 2000 rpm onwards. However, it isn't much, but for what I read could make it less.
Satisfactory performance for a 120-horsepower, enables me to have a discreet fun without overdoing it with the accelerator.
I believe that the gain in terms of performance is a 15-20 horses about, not more. I like the reattivit? of the car, or better, his sensitivity? to the pedal.

My questions:

How, how, why? and where you can? improve?
Where are the errors in the map (errors "philosophy")?

With your help, my main suspects of the lack of extension and change of the sound would be in the order of 1. maps lambda from lower - 2. advances - 3. injection times.

Thanks for your answer, and...begin to work on it :)

I believe that before you ask, the less you should introduce yourself

[sportknight]

m?....if this ? a trainer I am frank williams...

[peppearci]

Hello, I presented this morning in fact!

*sportknight: I believe I also, although it is only a fan mail. I seem to touch almost without logic, especially the time of injection...

[leandro89]

Sure, you've presented? I do not see your presentation

[sportknight]

the rail ? high,he touched both the pedal that maps the conversion(it was enough to tap one or the other) the times has made them starting from 250 bar when idling the car holds 300 bar for gi?...that serves to modify them to a minimum?..mmm another I can't remember

[peppearci]

A question: the rail to the top ? the main performance factor in this map?

[SandroMarciano]

absolutely no, if THE RAIL is NOT D? POWER.

[legendaryslave]

does not seem so to the eye, very well made close to the controls of the egr and spianni also map the rail too soon and too much stuff, you have to give him another logic on the forum there are very interesting discussions on this management, you can take a cue from them

[legendaryslave]

absolutely no, if THE RAIL is NOT D? POWER.
he said to me one day a type more pressure needs to make the pump more horses absorbs from the motor shaft do not know up to that point give advantages to the rail

[sportknight]

the snake that bites its own tail....for this one must not go too low...

[munro]

I s? 100 bar, most are more or less 10cv......
otherwise, the modules that raise the press of the only rail would not be served anything....
in addition, a cp1 i.e. to give 1350 bar at 1000rpm absorbs 4.5 hp or 3 kilowatts.
it does not seem to absorption by****around...and the same power that absorbs an air conditioning compressor in the end....
however, the map has a logic of its own using either method informed that the deceived to some extent
and it's our duty to chronicle the advances it maps lambda have been touched...
but the timing is just a little but they are touched...
the lim torque then ? to see the 30 and more percent per 1000 rpm, it seems to me much for the clutch....
then, however, between the times and rail increased by the low surely the turbo avr? peak uncontrolled rpm of max torque...

[magi1984]

I will say that I think in a few words is the map:

nm on iq or Quantity? fuel injected as it is called in the titanium - RIDICULOUS
injection time - RIDICULOUS
rail - RIDICULOUS
turbo - RIDICULOUS

not ? absolutely true, the form d? power why? tricks the ecu on the pressure, then, for example, the ecu believed to provide 50mm^3/s with a time of opening of 800us to 1400 bar but since it is the pressure pi? high (without the knowledge of the ecu) of the diesel fuel coming from the injectors ? pi? 50mm^3/s
Instead, if you increase the rail map the ecu I know? exactly the pushing, and lifting up user? a time of the bottom opening. There? pu? be beneficial when the duration of injection and lasts too addition to pms, or for a better atomization (according to me talk everything to prove).
The pump that mounts this 147 has the adjustment on the flow, so if it requires less pressure it will absorb? the less power.
The absorption of a pump ? negligible to ****llo performance, but ****l consumption I think affects...

[guidotacco]

in fact, you said right,and not only take a p? power but lowering it too much,lead to premature wear of the pump and injectors

[alfajtd]

map of unpacking.....

[ecutuningpro]

this ? a map that makes piet

[ugoboss]

in the first post ec, wrote that the map was made by a well-known trainer and then it was remodeled, and many well-known preparatory are used to make maps so-called standards, give a bit of power does not do damage and the car is fine, very probably here, then, are taken to increase the power and have changed everything because those who spoke did not know what he was doing.

[peppearci]

Exactly, dear ugo. The standard map ? cos? includes: torque limiter, injection timing, map conversion, and rail pressure.

Those, then, who has "added power," said he had done the following things: unlocking the torque limiter from 350nm to 400 (?), the increase of the injection 80mm3 with consequent displacement of the bp and adjustment pedal and unlocking of the value svrl to reach the 1700 bar set.

From that moment on the car, like I said, if I press a little bit more? on the pedal acceleration, change sound, it darkens as if there were no air or to intervene in any limiter.

Now, seeing the comments of other users, seems to be a mapping from the logic a bit VERY ridiculous.

I assume, therefore, that the performance gain ? almost? insufficient for an engine like this!

[peppearci]

As someone said to me that even the egr was properly and completely closed, I started from the step pi? simple.

I closed the egr resetting the control bit, and changing the curves. Is that correct?

[peppearci]

I think I have found another cognate egr *1c30EE . Also this should be closed by setting the maximum value to 12000?

[munro]

in edc16 you need to reset the controls....
not function the mod style edc15..

[peppearci]

I know that you have to reset the controls, but someone in the previous post has written that in the map posted on the first post of the egr not ? properly closed, so I assume there is something to be reset in addition to the two panettoncini...

Ok, the first attempt to "map informed" without deceit to the ECU thanks to the excellent thread to read, and I hope I have understood well, mixing the new knowledge with that already? "knew"

Work carried out:

Torque limiter set at 350nm to the team, then the request of diesel 76mm3 as the map conversion ori
Rail pressure increased to 1700bar with svrl, mod the intermediate pressure to the 4%
Turbo increased by 100 points, vgt slightly modified (serves in that way?)
Limiters diesel unlocked 76mm3 (I have them unlocked correctly?)
Controls the EGR disabled (c'? to clear something?)

-----------
Now you wonder if they are on the right path to a mapping correct. Raising even more? diesel fuel (for example, from 76 to 80, the maximum limit for the t.inj) avr? need to touch up the maps lambda and advances?

[jacktheripper2]

You also 80mm3 should be revised a bit the advances and the lambda. To change the lambda you need a log to see how much air you have, especially at high rpm. Once you have seen the log you have to lower on the basis of the air that you have to the various revolutions, of course, pi? lower and more? smoke. To do not smoke do not go lower than 1.05/1.1, for? with turbo ori holding it cos? high is probably not going to allow him? inject 80mm3 even at high rpm. It always depends on what you are looking for. 80mm3 them you can inject without smoke up to where you have more? of 1080mg air, when it starts to come down, and less or do smoke (not excessively though), or the injection will have to? decline.

have you noticed that the last message, and' 6 months ago right?

I had not seen that it was so old. For? since no one had responded more I wanted to give my opinion.
