Need help with: Flame-out under a certain %

[DrLicor]

Hey guys, 
I'm editing some configs for RSS/RO, and the last thing I need to do is to add some parameter that the engine (SRB) slowly reduces thrust and flame's out, just like the engines of RSB.
What do I have to put the config to get that effect? I'm searching for a while now, but haven't be able to find anything like that in the configs

Thanks in advance

@DrLicor you probably mean the thrust curve(s):

@MODULE[ModuleEngines*]
{
    .
    .
    .

    thrustCurve
    {
        key = 0.0   0.2   0.656   0.656
        key = 0.08  0.782 11.38  11.380
        key = 0.12  1.091  0.0    0.0
        key = 0.177 1.072 -0.301 -0.301
        key = 0.832 0.997  0.248  0.248
        key = 0.91  1.052  1.565  1.565
        key = 0.97  1.160  0.0    0.0
        key = 1.0   0.93  -4.794 -6.284
    }
}

(sample Castor 1 thrust curve values)

A thrust curve is defined by:

• the time (column #1)
• the max thrust at that point (column #2)
• the in tangent (column #3
• the out tangent (column #4)

You will need to use the FloatCurve Editor to get them correct:

@Phineas Freak, ah thanks, that was where I was looking for.
