    I've some doubts about the instruction overwrite values in special parameters.

    Well...I know the actual structure is setting number, non-translated/converted value prefix, translated/converted value postfix, overwrite instructions and I'm using this way to put real AntiRoll values into the car .HDV file. As I do not have fixed steps I've to work with special parameters and overwrite instructions.

    ...but the problem is that I've different car behaviors using differents standard value prefix in the main range (the red XXX.XX step value in the Eg.).

    So...I'm asking if the range step value is bypassed (I think it is not as I've huge differences using different values) by the special instructions (the green values) or there is a correlation (?) between the main prefix value and instruction values..

    This is a cut from my .HDV file;

    FrontAntiSwayRange=(29421.0, xxxx.xx, 97)
    FrontAntiSwaySpecial=(0,"3.0"," kg/mm",29421.0) // T-13 solid @ B-270
    FrontAntiSwaySpecial=(1,"3.1"," kg/mm",30401.7)
    FrontAntiSwaySpecial=(2,"3.4"," kg/mm",33343.8)
    FrontAntiSwaySpecial=(3,"3.9"," kg/mm",38247.3)
    FrontAntiSwaySpecial=(4,"4.0"," kg/mm",39228.0)
    etc...etc...///
    FrontAntiSwaySpecial=(96,"213.1"," kg/mm",2089871.7)
    FrontAntiSwaySetting=78

    Hoping someone can help me to understand...

    Thanks :)

    Sorry to insist...but I'm stuck with this and it's very important as I'm using a lot of those special parameters...

    I've take a look at ISIs .HDV...and there's almost the same stuff, but honestly I do not understand how they're getting the XXXX.XX step value for the special parameter list with instructions.

    Please ISIs...:)

    Weird situation here.

    106 reads...0 replies. Seems nobody have an idea about how those parameters are working...and this is another confirmation that we've a huge lack of information...:)

    We need more "Luc" here...;)

    I'm no expert but it looks like you're missing the "" around the last numbers

    FrontAntiSwaySpecial=(0,"3.0"," kg/mm",29421.0)

    Megane:
    FrontAntiSwaySpecial=(0,"231"," daNm/°","91674")

    Nope. I think qmarks are for show the value in the setting menu (numeric/text) or are not mandatory. This is a F3.5 section:

    FrontAntiSwayRange=(264779.55, 396188.66, 11)
    FrontAntiSwaySpecial=(0,"27"," kg/mm",264779.55)
    FrontAntiSwaySpecial=(1,"31"," kg/mm",304006.15) // (setting, non-translated value prefix, translated value postfix, instructions)
    FrontAntiSwaySpecial=(2,"38"," kg/mm",372652.7)
    FrontAntiSwaySpecial=(3,"47"," kg/mm",460912.55)
    FrontAntiSwaySpecial=(4,"62"," kg/mm",608012.3)
    FrontAntiSwaySpecial=(5,"79"," kg/mm",774725.35)
    FrontAntiSwaySpecial=(6,"98"," kg/mm",961051.7)
    FrontAntiSwaySpecial=(7,"131"," kg/mm",1284671.15)
    FrontAntiSwaySpecial=(8,"206"," kg/mm",2020169.9)
    FrontAntiSwaySpecial=(9,"309"," kg/mm",3030254.85)
    FrontAntiSwaySpecial=(10,"431"," kg/mm",4226666.15)
    FrontAntiSwaySetting=10

    As you can see is pretty similar to mine...but I'm asking about the red value, that (in my head) should be bypassed by the instruction list...but it isnt and this is a problem because I do not understand how this pre.value works.

    I think it still works the same as rf1. The special section is for how it will look in the garage.

    setting 10 will say in the garage 431 kg/mm but rF2 will use 4226666.15.

    I could be wrong.

    Those long numbers are conversions from N to Kilos. :)

    Specials are usefull for using non standard steps between values. In this way you can program the car as it is in the official car manual.

    Old standards was using range and fixed steps.

    Those long numers are in N/m.
    Knowing that 1 kgf equals 9.80665 N then

    (4226666.15 / 9.80665 ) = 431000 kgf/m OR 431 kgf/mm

    Badly news is that this explains only the converted values of FrontAntiSwaySpecial (from 0 to 10).

    The number in red remains misterious to me too unless they could define the limits (extremes) of the AntiSwayRange, as:

    (396188.66 x 0) + 264779.55 = 264779.55

    AND

    (396188.66 x 10) + 264779.55 = 4226666.15

    So the steps 1 to 9 spread between those extremes according to the real car.

    Hope this can help in anyway.

    And hope this is correct (lol).

    I know about N/m, as you can see in my first cut&paste taken from my car....those are N/m to Kg/mm conversions.

    About the rednumber.....nice thought, but it works just for this specific example. I've tried to do the same with other ISI stock .HDV and it doesn't work....and if you think about it you already have extreme limits as the first and the last instruction paramters... :(

    BTW thanks mate.

    Preliminary analysis shows this to be a bug.. I'd imagine our guy will solve this for the next build.

    I can confirm special parameters are now working.

    Thanks for the fast fix! :)
