    They are (in the grande punto 90 hp ) 24 curves, but if there are curves for each rpm are curves on the basis of what?
    Thanks.
    Values are based on the rail pressure and iq in mm3 injected. I have not seen the map but it may be that the abrupt behavior of the machine is due to excessive increases of this map. If you have the tool to write you could try to replace the golds that map and leave the rest

    add me to the request of Danny... what is that?

    Ok then , let's talk about the map injection times, if not, we confuse.*****and you say, taking one of the 24 curves to the sample, the pressure goes up and times go down..also you increase a little the values in the right part of the curve? of all the curves?? then I'd like to understand what it indicates for example the 15 curve, such as 20, etc...that is, I understand, which are the values of IQ rising, but how do I know which corresponds to half throttle? or which 60% of the pedal..??etc.. not to go to the eye..

    then the 24 curves is equivalent to iq (es: 1 curve refers to what happens to 0.19 mm3/str) , instead of the 16 values that you will find in each curve refers to the time of injection (mm3) of fuel to be injected (ex: in the first curve, the first value you will find is "900" then, means for injecting 0.19 mm3/str with 100 bar it takes 900 us)
    the conversion factors are 0.002930 for iq (unit of measurement mm3/str) and the rail pressure is eprom x 2 (unit of measurement is in bar) I hope I was clear

    Enough, thanks Alex..***** and you know that the first is 0.19mm3? " str "stands for? I do not understand, then at half throttle ( for example)in which the curve.. maybe I should cross it with other maps, like the one pedal or rail pressure? to understand how iq is asked of you in that moment?
    it is better to increase the time where the pressure is highest, to avoid smoke? however, if you want to give more to the lower rpm, since the low pressure is lower, it is necessary to increase a bit (4-5% es) where the curve is highest? is this right reasoning?

    hello is 0.19, because the first value after the 0 in the y-axis is 68 and multiplied by conversion factor 0,002930 there to 0.19 mm3/str, str I don't know what it is but still refers to the request for diesel fuel total rail pressure, I would recommend to lower the timing to avoid smoke because increasing, you'll be injecting when the piston has already reached tdc and then accordingly you will have only a washing of the cylinder with its smoked correct me if I'm wrong around I read that in order to have something the more you should increase the max of 150 points, the map advances correct me here if I'm wrong

    Now I don't have the map in front of, after control for the calculation.. as regards the timing of the injection, if them lower, immetterai less fuel and go less!! and get them up too,instead, fumerai! my trainer had me raised a bit, the right side of all the curves, increasing the time pressure a little higher, ( the car does not smoke).. now I was wondering, if to give more low I had to increase the left part of the curves, the one with the peak so to speak( the time at lower pressures). you Alex you don't know the curve 12 in which the position of the gas/accelerator is?

    the curve 12 corresponds to half the iq so I guess a 50% acceleration since the flow is controlled by the accelerator pedal

    str stands for stroke, or stroke or phase ...incomma mm for injected!
    does anyone know why there are almost always 2 maps? map 1 and map-affine, then it is not always so equal, in fact... what is the second?

    should be the correction of the main
