opinion the map alfa GT 1.9

then if you delete the MAF (mass air flow sensor), the ecu reads the air based on the MAP sensor (air pressure), and makes a conversion to me still unknown that allows you to derive the quantity of air, in fact if you disconnect the maf you from damage but walks in anyway, I can't see the screen, but as far as the limiters iq, and according to the conditions of the vehicle, i.e. when is 8192 i.e. TH2O between 40 and 105C? if I'm not mistaken allows you all that fuel, i.e. in the optimal conditions, there are 3 limiters the first, and in F of the temperature of the water, the second, and the one just mentioned, that, and anyway, depending on water temperature 3? and balancing fuel pump that I have not understood yet, but if not the moddi limits, the problem, unfortunately, I have not yet resolved, with the MAF unplugged the car runs better and does not smoke, starts to smoke on the 3750, I thank you for the compliments, I am passionate about and I spend a lot of time to these studies, because I really like to enter the optical-ECU-BASED, practically in the short became a ECU....ehehehe when I feel bad attack, the diagnosis, and I see the DTC....joke thank you

Guys today I did 20 25 scriptures testing the PID controller and putting ori map VGT or an overboost (as you want), I will explain what I understand by trying, and I'm attaching the exact addresses
*1E1D78
*1E1E6C
*1E1F60
*1E2054
these are the 4 maps to PID, factor D, i.e. the Derivative
from the tests made on these maps, are used to contain the pressure Peak, i.e. in conditions of maximum load transient (to have a short at 2000 rpm crush all) are used to contain and control or sweeten the peak of an overboost, in BP, we find the RPM and QI in MM3 the resulting factor Derivative.
Scrolling in 2D, we find the other 2 maps similar
*1E2148
*1E2248
these, however, are the factor Integrative, BP ditto to those of the first RPM and MM3 of course, the result will be the Integrative factor, in my opinion, these control the progression of the Prex Turbo and correct any smudges in acceleration but do not control the peak, so that the pressure remains faithful to the one set in the map.
finally, there's the other 2 maps
*1E2408
*1e2508
who are the proportional, BP ditto of the above, then RPM MM3 and the resulting sara, obviously, is the factor that is proportional, in my opinion, these control the pressure and make sure to keep it constant if the gas constant and driving example in the plain of 90 km/h without variations of gas and does not make the climb, keeping it in the target set by the map turbo.
I hope I have done something good I wait for a few BIG give me a hand or an opinion, we would like to thank my turbine for having endured a peak-to-1,75 bar of pressure.
PS moddando the PID changes a lot, the delivery of the machine, very very

It's great that you did all of these tests.
From what I know myself to? the P is used to determine the 'speed' is reached the objective,The need to keep it stable or still have to follow the values set as the goal, the D finally ? the last controller that sometimes not ? even active (also depends only from the sw to the sw)? active in the management of the rail pressure that she also has the pid controller to adjust the lens and measured.

[jovandj]

Hello Jack ? always a pleasure to risentirti in my case, the factor D ? active in the map by putting it to zero or otherwise lowering I noticed a peak uncontrolled pressure turbo

[jovandj]

M has piqued even at 1.8 with the one off or zoned lot, I touched a lot, but I have been very close to what you say, you in the end the progression of the prex turbo and speed? of achieved are comparable with respect to the factor, while the factor P controls the stability? I've expressed with a constant load and containment would keep it stable, so it goes quite well without the Maf for the speech that you mentioned that lost performance after a while, it was just that now he seems to remain constant and good to go.
In accordance with the map deceived the pid are deceived by having the 2?bp mm3 of course, being more correct, less in the case of the deceived, I would stress, and that is why the deceived go so well at the bottom, and with the informed if touches the pid the machine changes a lot

Jack now that you reread carefully, there are controllers on the p-rail??

[jovandj]

today I made 2 other 3 tests, I noticed that the PID controller corrects only, in fact, if we touch the map VGT and the raccordiamo I have taken away then open the 5% fixed from 1750 to 5000, I noticed that the correction was significantly less I have also noticed that the pressure is more stable, so if you can linearize the more possible the VGT from the map present in the driver of the ECM, the pid do a minor work, and can be left out

[Errecinque]

Have you tried To do only the adaptation Bp of the last axis to 80 mm3 Interpolating with Excel, the values of each rpm from 5 to 70 Mm3 .

What maps are we talking about? ?

Of the map in the driver vgt you said before
