    Vtech Tunes..

    Running a 8375 169 ......202 tune..

    there are other tunes available..

    8375 170.... 201
    8375 176.... 201


    I know what all the other numbers relating to the tune mean..

    I also know that 169, 170, 176 relate to fuel..

    which one is "richer" the 169 or the 176 there is no explanation anywhere I looked..

    i'm looking to "fatten" up the top just alittle bit for reason of only removing the flame arrestor..

    A file can be named like this:
    VT11 8500 165 34 36 15 AGR 101
    VT11 = injectors,in this case the VT1100 cc from vtech
    8500 = rpm limiter
    165 = value for fuel, the fuel is scaled for your application but we might have made special versions where we added or removed fuel if this is the case then there might be a value in % after.
    165 +5% means we added 5 % fuel to this map.
    34 = value for ignition advance mid range
    36 = value for ignition advance top rpm
    15 = psi target value at 8500
    AGR = Aggressive throttle settings
    101= version info, se webpage for comment regarding this version! Alway use the latest version. But check notes if it is a special version like raised idle and similar.
    42 8350 167 41 29 15 101
    42 8350 187 41 29 15 101
    50 8350 167 41 29 15 101
    50 8650 167 41 29 15 101
    50 8700 167 41 29 15 101
    80 10500 916 41 29 15 101
    80 8800 916 41 29 15 101
    Stock File


    my money is on the bigger number means more fuel.
