    attention, doesn't it ? only the result of the delay of the opening of the needle, but essentially to those pressures, the pressure losses increase exponentially.
    Speak to the low pressure because of rising pressure, the value decreases

    yes, the opening of the needle should decrease with the increase of the presisoni, instead, to the speech of the opening time of the injectors ? pi? complicated, since the flow rate should increase linearly with the pressure, instead of the load losses increase exponentially, for which we do not have a straight line to identify the curve of the opening time, but a curve with exponential profile.
    Even if hypothetically we were to go beyond certain limit values with the pressure we would have that the boundary layer would develop for a large part of the surface of injection of the injector, and this creates the phenomena molot dangerous. The VAG that run with a pressure of 2000bar break very often the injection pump, and I think that the thing is due precisely to this phenomenon, for which I think that is not the case of fasciarci the head with the accounts useless because anyway ? an experimental measurement at the base of the map of the times, to us, impossible to realize.

    Indeed, my calculation was directed to the increase of the flow rate as a function of time of aperturra and not in function of the rail pressure as you say requires other knowledge of the physical

    no, knowledge is not enough, you also need specific equipment for the detection of the experimental data.
    Furthermore, the flow does not ? linear even fixed a rail pressure, in fact, the load losses are a given variable here.

    So I have to presumerr that also the map time fiat is simplified without counting these constants piiche with the formula applied to return all the values, right sandro? Tolerate an error rate acceptable

    ? strange the cpsa, why? on these injectors seem to work roughly, but much better than my system, instead of on the jtd 115, for example, presents data completely inconsistent!

    already very strange indeed, I would understand if they did that for simplicity of the approximation as a calculation, or there are substantial differences on the functioning on the basis of the pressures of the 2 types of injectors

    here are the corrections for the calculation times for the 150 hp, I was facevdo a rora and I took the opportunity to check, the t4empi are different, I assume that the injectors are not the same

    hello dear! I'm sorry, but I was out...and I could not answer
    anyway, the limiter of the lambda is in 1cd312
    and 1de032 should be the switchoff lambda...

    wrong limiter lambda sorry 1cd55a
