    In fact I think the speech to make concerns more? factors: com'? true that with the increase in torque decreases the load on the pedal, ? altres? true that the speed? of the exchange, and then the ratio of Rpm/V-Eff (Schemes & Speed?) remain unaffected because of the gear ratios of the gearbox that ? to be considered a constant; therefore, it is necessary to consider the best volumetric efficiency, which is reflected in a reduced loading on the pedal to reach and maintain a given speed (Rpm) and, therefore, a particular fast? (V-Eff), which as mentioned above ? the result of a constant ? the gear ratios of the transmission. A higher efficiency in parit? load.

    But not limited to:

    Car Stock -> 3^ Gear - 80% Load - 3800Rpm & 90Km/h
    Drive Mapped -> 3^ Gear - 50% Load - 3800Rpm & 90Km/h

    Then,

    Car Stock -> 3^ Gear - 80% Load - 3800Rpm & 90Km/h
    Drive Mapped -> 3^ Gear - 80% Load - 4200Rpm & 120Km/h

    And this, according to me, determines the true reduction of the power consumption of a comparison between car stock and mapped: in parit? load a drive mapped to develop a regime more, and then a speed? greater or equal? regime and speed? ? need to less because of better volumetric efficiency.

    I hope I've explained!
    Quoto! Everything is according to me in being able to make ends meet, the increase in mg of oil with a value slightly higher to make the most of the engine, but not so high as to consume still more the engine...I am talking about the map soft..

    I'm not convinced...eliminamo reasoning for a moment, the control units and the percentage of the working engine and load pedal angle and ragionamo for a moment, no-frills electronic means.
    if I have a car with 175cv at 2000 rpm say 2000 rpm and then assumes that in order to have these 2000 rpm and I have to mash the pedal a number,let's say a quarter of the race,I have a speed? that ? a constant,you said you, too, of 140km-h if I in this car dont make the engine and the port to 350cv and leave all the rest unchanged to have the same speed? 140 km-h 2000 rpm, do I need to do to my engine, and always a quarter of the accelerator, do I need to give to get those rides! the only thing that will change? sar? the acceleration and in a blink of an eye with that pedal schiaccito the same way to me, porter? a 140km-h...
    with the ecu of a half hour, and worse, because if no electronic control I can give a quarter of gas plus a quid for the car viaggera more quickly, but with electronics this is not the case because the ecu ? a German of the pipe and not cheating on your regimen!
    if 50% pedal gives you 2000 rpm with any other sw from super cv at 50% of pedal always 2000 rpm do you give? you can not escape.
    then you can create all the formulas you want, but if the speed to the revs of the engine ? a constant does not there are means to do it vary

    First of all, I did not invent any formula, but I was trying to reason with you others and to yourself which I think is much more? experienced than me; secondly, the difference is in the load from the pedal: dov'? wrote that after you worked on your car you have to give the same load as the pedal to get the same Rpm then the same V-Eff? Even if it were as you say yourself, that is, that the varying of the power does not vary the loads, with a good map you might still have a reduction of consumption because of better volumetric efficiency IMHO.

    sorry,I usually remap from 70% throttle...
    if I press the accelerator to the 50% constant why? there should be a drop in consumption?
    this ? the thing that I can not explain

    it may be that under a 50% load engine smagrisce lamappa so as to inject less fuel? I see, so,on the contrary,so we require engine load from 50% to on the map to give more fuel or more pressure an overboost,more torque and performance....don't kill me if I say crap he

    I believe that it is docuto pi? to the fact that usually we increase a bit the turbine, which tends to lean the fuel mixture because? increases the flow of air

    but you want to increase an overboost or the constant pressure?

    hello all, I am new to the forum and I was reading some of the discussions, even the old
    according to me, after mapping the ecu ? pretty unlikely to speed? constant with a given gear (V-type to 100km/h) it is possible to reduce the power consumption when the surrounding conditions remain the same (friction, aerodynamics, etc...). the load on the pedal will be? pi? low but only because? the new map injects the same fuel flow rate, e.g. at 30% load instead of 35% of the golds.
    then there are tricks that make you consume less, in any condition (type deleting the DPF/EGR) and operating conditions of ir? favourable for the reduction in the consumption of
