this will be good eoi for wot in last picture. if you dont look for high performace than its ok.

i still think that do you have some problem with maf becouse od low reading on high rpm with that boost. I have 1150mg/i @3500rpm, and same boost. Is it stock air filter? is it clean?

You mean EOI in picture v13.5?

Everything is stock, and about clean status...hmm...actually I don't know. I replace it last year when I bought car...and from than I allready passed more than 20k km...so maybe is time for new one.

yes. after 20k its crying for new. :D

I tried today that reamap with changed IQ values on axes for SOI, but something is not OK. Car is not pulling well after 3000 rpm and at 4000 it is like stock...not pulling at all.
In logs I can see that SOI is going too early for requested IQ, it is used value from last column, not from other where is should (because I modified x axe, like on soi picture that I attached few days before). This means that I changed wrong axe and that axe is actually not for SOI.

Can somebody please confirm to me right addresses for x and y axes for this maps (earlier in this thread there is my ecu binary):

746B0 - INJ basic map, start of main inj. without pilot inj. 16x16 (x=73146,y=7311A)
7316E - INJ basic map, start of main inj. with pilot inj., 20x20 (x=73146,y=7311A - same as above but only first 16 values is used)
748B0 - INJ basic map, start of pilot-injection, 16x16 (x=73146,y=7311A)
7A46C - RPC basic map, setpoint CR-pressure, 16x16 (x=71AC2, y=71A56) - and if 71AC2 is OK, is it shared with some other map?


Thanks in advance!

This is log from that run where I was modifying (obviously wrong) axe:


So, I restore stock values on that axe but now modify railP map completely; remove two columns at low IQs to allow shifting table to left and make room for two more columns for 65 and 75 IQ. After that, I make run on same road, short acceleration in 3rd from 2000 to 4000 rpm:



To me, this looks much better than before (i remove afr and boost to allow better pooling data rate from ecu).
Car pulls very well, does not have "limit" on 4000 rpm.

My only concern is if railP can be quickly adjusted like in map - I have to drop railP a little at 55mm3 to allow injection ends around TDC; otherwise, with modified SOI at 55mm3 column (last one), injection will end far before TDC at rpms > 3500 ..and that I think will not be good.


Btw. whyle remaping this time, my MPPS drops communication with error and car could'n start anymore :sick: . When retryed to write...MPPS managed to write software successfully :clap: .

I've sh*t myself because of that...I don't know am I just been lucky because MPPS write software to ECU back again...

lol. you have luck . :clap:

try with soi 19 @ 3800rpm, and 20 @4000rpm. now you have EOI BTDC for that rpm and iq.

I have corrected CRP and SOI maps...so I think now I have good values for EOI.


I have done some modifications in low revs and iq, in eco turbo & n75 maps...but in logs it seems that it is not applyed.


Boost should be under 1200 mBar, around 1100mBar, but in logs is over 1200 mBar and that would be correct value for sporting map :?:

if you have actaul boost higher than desired boost than open vanes in n75 map more.

I'we finally changed air filter :) And maybe found cause of airflow drop...



In area marked with 1 I found 5mm hole in plastics...like it was melted down. So, probbably there was air entering turbo without passing through MAF...so boost was OK but measured airflow was less than real.

I also found that there is some pipe junction (marked with 2) just before turbo that is going back to airbox (marked with 3). What is purpose of this pipe? It is not loggical to me, because if this is not restricted pipe...than there is a plenty of air bypassing MAF. Or there is some one-way valve in this pipe?
I should check this pipe, because maybe is also damaged and false air entering by hole (if any).

2 i 3 su za rezonator boksa filtera. Ona treba da bude zatvorena i tu vazduh ne moze da ulazi. Proveri, ali ces morati da skidas celo kuciste filtera jer je rezonator zakacen na njega. :)
rupa kod broja 1 ti je jer je leglo crevo na hladnjak pa se otopilo. Prvo to zatvori pa onda odradi dijagnostiku da vidis jel maf ocitava vrednosti dobro.

Rekoh ti da imas neki problem sa usisom. Sad si ga nasao. :thumbup:

number 2 i 3. is for air box resonator, and oil catch. it is restricted.
number 1 is your problem with maf. and what about pipe from turbo to air box? is it ok?
