Mapping EDC15C7 Alfa 147 115hp 332 536

[gionag]

Hi,
I have just been in to introduce myself, and immediately carry over here, my doubts and my uncertainties.
I started to do some changes (such as software use WinOLS), trying to maintain a logic, by modifying the BP result and calculating the values in an intelligent way (maybe).
Because I want to understand, and not simply run of pi? the machine, I tried to follow a sort of logic in the changes, avoiding throw percentage increases here and there? haphazardly, hoping to catch us.

Probably ? all wrong, for? if we don't try, I'll never know? never

At the moment the map ? loaded in the car with the results, in my opinion, already? pi? that satisfactory.
before I had a map made a trainer in my area (it was already? on the machine when I bought it) and I have to say that the machine with respect to the "first" has the same (maybe the best) shot at the top and I have even less fumosit?.

I attach everything, cos? if you want to you can check. if I can I put the mapppack made by me (no damos) trying to include all of the maps described correctly.

Of course all of this ? only the beginning.

The logic that I followed ? was the following :

- Egr closed by Bit Switch (I made the map by putting everything to the max, even if there was no need)
- Modification of the request target to the pedal
- Adjustment and BP values AFR on the Smoke Map
- Adjustment Pressure turbo (with limiters) to s? enter a quantity of air sufficient to oxidation of the new deal? fuel.
- Edit "torque Limiter" s? entering 80 Mg to the regime of maximum efficiency
- A modification to the iq limiter to make sure that it passes all the required
- Change the time of iniziezioni (with pre-iniez and without)
- Change to the Rail pressure (and consequent limiters)

I think I have to increase the map only "serving" avoiding smarmellare increases everywhere.
The advances at the moment are Stock because I have yet to figure out how to formulate a strategy.

From time to time EcuScan I see that they are injected, all the 80mg and the air that enters ? right, the turbo sometimes behaves perfectly at other times spike a bit (for a few seconds), but the pressure came on the values indicated by the map.

I take this opportunity now to ask you something ? true that on the 1.9 maps duration (that are 16x20 grommet) are actually? read up to 16 (16x16), while on the 2.4 is used all the axis ?

In the archive there should be all, I also put the hex for those who want to check without winols.

Let me know what you think... pendo from your lips (fingers).

sorry, I noticed you have attached the wrong version of the file. I have also included the file ORI.

332_536_Alfa_147_rev2.zip

I've tried to optimize the map duration. first of all, I changed the last two bp (of the three equal to 70mg/cycle) leading them to, respectively, 80 and 90 mg, respectively (cos? to better follow the injection request 85mg).
for the duration, I used an excel function, that ? "FORECAST" which given a interval is known, allows to predict with a certain degree of security, "statistics" what will be? the next value.

I took those numbers and I placed them respectively by 80 and then 90 mg.

doing a log, I realized that in the presence of the maximum fuel injection and a new turbo pressure request as we might have expected, I had a certain discrepancy between the value "required" and the actual one, for the uniformity of all, I reduced the map of the geometry by changing even the bp and resizing in the area you need, using the system of the linear forecast.

new log and now everything seems to be apostles.

If you give me your blessing, I would like to go to the advance times, just that I lack a certain confidence and fear of the damage is done I left everything ok. We can try to do something together ?

Thanks

[gionag]

and, of course, I am forgetting to attach

here it is -> mappa_85_test.zip

? been done with *********** and a module with ELM 327 of that since bluetooth is not the world of "sincronicit?" on the data...

[gionag]

I rimangio everything that I had said, the problems of over-pressure turbo is absolutely not fixed.
I attach the last log made at the back, short pull, but the adjustment on the turbine ? painful.
I want to put the map vnt original.

the cases are different:
- there I realized a bat
- the pierburg ? skipped
- in addition to the map from me changing and there are more

help !

Strange, this map I had already? in the database of winols... anyway: nice effort to use logic, but increase the whole axis, and then all of the values in the map does nothing, just working on the last few points.
Attention that the flow of diesel fuel are in mm3/s and not in mg/i, this makes you calculate the afr too lean.
The limiters turbo are too precise with the pressure base, a 100mbar difference ? appropriate to not give you fault as soon as the turbine pike
*79E92 leave it to ori, who doesn't ? anything you may need!

the 332_536 alpha ? pretty common from what I've seen

anyway: nice effort to use a logical, but increase the axis, and then all the values in the map does nothing, just working on the last points.

I think you're referring to the map fumes, the gains (in theory) to reflect rescale the x-axis (the air intake) that I had to do to make space for the new bp.
probably it was enough to change only the last column and recalculate only for that.

Attention that the flow of diesel fuel are in mm3/s and not in mg/i, this makes you calculate the afr too lean.

I have done simply MASS AIR / Nuovo_AFR (Nuovo_AFR = ~14 as the latter bp ori). maybe I have to divide ultriormente to 0.85.

So you are telling me that all of the values of IQ on edc15 are in mm3 ? The value of the intake air is read from the mass air flow sensor ? always mm3 ?

The limiters turbo are too precise with the pressure base, a 100mbar difference ? appropriate to not give you fault as soon as the turbine pike

modificher? accordingly. Thanks

?

in the meantime, I was doing a mental journey... correct me if I'm wrong.
the mass air flow sensor should return values in mg/dm3 (or mg/lt chedirsivoglia). the quantity? instead mm3.
I was doing a calculation:

atmospheric pressure : ~1bar
pressure turbocharger relative : 1.3bar choice (from the map)
pressure turbocharger absolute = pressione_relativa + atmospheric = 2.3bar
density? air conditions, the pseudo-standard : 1225 mg/dm3
displacement : 1,91 dm3
per cylinder : 0,4775 dm3
efficiency volumetric : 90% (x0.90)

trying to see how much air enters a cylinder I would do :

pressione_sovra_alim_assoluta * volume_cilindro * efficenza_volumetrica * density? air = 1210 mg/lt
PLAUSIBLE ?

[gionag]

Actually now has more? sense reading of the AFR with the conversion,
before I incorrectly mm3 of IQ for the mg/lt of the MAF. and gave me the column pi? to the right (maximum MAF) of about 1:14.9 which, according to what you say, should you smoke like a chimney... and in fact I do not I explained.

? now to redo some account.

rechecking the AFR ori comes out that alfa romeo has decided to use 17.52 ... I andr? a p? pi? load, say 16,5
with the new maf calculated above would 86.27mm3 correct ?

*SandroMarciano : 79E92 fixed, maybe I had missed a couple of mouse clicks

[gionag]

After the advice of sandro are qua. I lightened the changes and I placed the map turbo (at least I think).
Still missing the RAIL (as I had done it before does not convince me in the least), and SOI. I look forward to some pious soul,
