    are you referring to the istersi of the N75-wastegate?? and, anyway, for your info megamind the volumetric efficiency of a 4 valves per cylinder and abundantly more than 95%....I believe even more now that for the design of the inlet and exhaust ducts for the choice of the timing of the distribution you are using the most powerful sw simulaziuone 3d...85% of VE, and a typical value of an engine 2 valves per cylinder...
    A rider does not create queues even in the car...
    a automoblista create queues even on a motorcycle...

    but then there is a % fixed efficiency, or ? variable depending on the engine?

    varies from engine to engine, but great lines you can? to say that for a 2 valves per cylinder st? around 80-85% for a 4 valves per cylinder ? 90% to 95%, while for a 4valvole for the cylinder very driven type engines from the competition with a yield in that can? vary from 100 to 120%.....here you can read a little bit about...

    Hi all, after a periodaccio of the many problems I go back to the study of the localization maps of my ecu...
    I leave aside the turbo vnt for now to focus on the other...

    someone who has dimistichezza in recognizing the maps could help me with these addresses
    and explain to me what is their purpose and how they work:

    CA2C4 (Hysteresis??)
    CA390 (Hysteresis??)
    (shouldn't have to do with the management of the DPF)

    and with these:

    ED5CC
    (1300x140?=>3819) (between maps prex. turbo and lim. turbo)

    F4310
    (9000x6000=<2479) (zone prex. rail)
    F4E0A (7650x4400=12500) (zone prex. rail)
