    No she does not smoke, maybe the map Maf is not ? made very well for? when I do the log I mark an injection-approximately 100mm3.... For the turbo pressure so that the 1749 1.5 is almost on the surge Line so it should hold up... And then has to stand For just because? I am going to put a turbo new type 2256 or 2260 then will see?....

    to 100mm3 that MAF read from the log ? and in the map size limit of fumes that bp did you match the 100 ?
    calculate the pressure of the turbine halls, a consequence of the increase of the diesel, so I believe, that in order to have a PREDICTABLE behavior of the pressure turbo would have to be adapted in an intelligent manner also the map of variable geometry.
    from what I understand, this device works in open-loop then the only reference that has the machine to adjust the pressure ? the map (the maps for the accuracy) of the variable geometry.

    Sisi maps of the pieburg the I have already? adapted, in fact, before I had peaks of 2 bar and I have tried to eliminate the turbo lag, while keeping it a bit more? closed at low rpm( they are the tests I have done I don't know how to edit it to perfection) .... For the maf, I have never logged in nn but it seems to me you have never read a parameter name maf in ***********... The Bp, it seems to me that I put it to 1400 mg why? from a log I had of that value

    in *********** find "intake air quantity" = MAF
    if you have closed the EGR by-bit, the value "wish intake air quantity" should be set to 0.

    I tried to do some account and it seems to me that in order to have a maf 1400 you should have about 1.9 bar pressure...
    do a log and see the various pressures which values of maf you have...
    why? it seems to me to be little sense in having 1400mg/cyc maf with "ONLY" 1.5 bar relative...

    Ok prover? to make the log as you say... But the parameter intake air quantity I from values just above 1400 I remember why? I did some time ago

    I don't see anything strange..
    1400 ? a value that is quite high.. and I repeat, if you read 1400 I would expect a pressure of not less than 1.8 bar
    of course, the reading of the maf depends on other parameters, including elevation, temperature, and humidity? air.

    You know, now that I think ? true... When I made that log I did not have the gauge and I know I have exaggerated peaks of pressure.... You're a genius ... Me? the log and update

    genius... I ? ahahahah
    verification, why? suspect that now... pressure to the turbo more? low, you will be lowered as the maf, and then you should re-check the limiter fumes...

    I redid the log , the new MAF ? of 1233 mg ...I modified the b.p. map of fumes with a maximum value of 1250 and I calculated the new values to get a afr of 15 to a high rpm, 16 to the medes and afr ori at low revs ...the formula that I used I believe is right and just simply make mg air /arf to /0.85 = diesel fuel in the mg (the value to be placed in the box)

    then...
    all good the only thing...
    ? who want to be precise, the 0.85 for the split ? a fairly approximate.
    if you look at the data sheet for the diesel Q8 show that the density? 15? it oscillates between a minimum of 0.82 and a maximum of 0.845. and calculates that the rise of temperature, the density? decreases... to physical forces that govern the entire universe
    so if 15? you have a maximum of 0.845, the last I see of 40? (temperature enough versomile of diesel injected) both of 0.85 as you f? usually.
    Everything depends on the accuracy that we want to have...

    Could you tell me what are for you the LOW/MID/HIGH rpm ? for me it makes little sense to do this subdivision...
