    Use a kessV2 clone...

    A couple of questions..
    - I'm adapting a number of axes of torque, the IQ, and the rail with the new values.... is that okay or no?
    - Torque limiters, once arrived at 500Nm, should I get them to team up at the end?
    - In the same way with the pedal, I have to set it with the value max of 500Nm up to the end?

    1. If you adapt the values in the map do it right
    2. 500 Nm at 4000 rpm, the equivalent of 280 Hp
    3. As above

    A ****llo theoretical with this map I have a situation...:

    3500Rpm - 219cv(theoretical) - 190cv(considering a loss of 13%)
    4000Rpm - 244cv(theoretical) - 212cv(considering a loss of 13%)
    4200Rpm - 246cv(theoretical) - 214cv(considering a loss of 13%)

    ...in theory....!!!!

    Sorry....I'd like to know the formula from which derived the cv theory. Thanks

    In the diesel the amount of fuel injected determines how closely the amount of power produced (up to a certain limit anyway).
    We can roughly estimate the amount of torque that can be produced by injecting, for example, 1.5 mg x cylinder and then by injecting 60 mg / stroke in a 4-cylinder engine that gives as a result about 1,5 * 4 * 60 = 360 Nm of maximum torque.
    Now we can calculate the power of calculation from the pair can be done with the formula:
    Power (hp) = (Torque (Nm) * rpm / 7121.
    By injecting 60 mg / stroke at 4000 rpm 360 * 4000/7121 = 202 HP.
    this, of course, in theory, because the formula does not take into account many other variables...

    a automoblista create queues even on a motorcycle...

    Theoretical in the sense that they are those due to the required torque in the map to which we subtract mechanical losses that usually are about 13%.


    Anyway, new update...
    - maps lambda clipped to a maximum value of 1.2...


    Certainly, as mentioned by Munro, should be put for the whole of 1, and also less, but because I fear that smoke like a ferry I would like to first do a test like this.

    X Munro... I'm sorry, I had read read the the place to log in...
    Anyway, currently I have a self-diagnosis Delphi, as soon as I can comprero' the cable inpa... Already I have seen a couple!

    inpa say...and how good it is? the bmw are a bit steep to be logged....I have heard good things about the bavarian tech but I don't have but seen one in action..
    anyway back to the speech map the request from the pedal should be higher than 500nm of the lim couple, and from the nm>iq, otherwise the ecu has nothing with which to interpolate the data...

    I correct myself and 1.5 are not mg injected but it is a number of equivalence as a function of the torque estimated to be produced from a cylinder..
    the calculation remains almost identical anyway...

    Inpa and the diagnosis official bmw until 2008, after they have changed the system...
    For the formula, and the one that I used I also.... I have made a spreadsheet that gives me a graph of torque and power... always theoretical
