Noobish Part.cfg question

[rayrocksweet]

i feel as tho im am doing something terribly wrong and am about to get blasted for being an idiot, but i cannot figure out how to lower the fuel consumption of 2 parts; namely the turbofan and toroiadal aerospike. Now i have looked for the answer to this question and it has eluded me. I have looked at sites including scott manley's tutorial (

he has helped me a great deal with this game) and the ksp wiki ( http://wiki.kerbalspaceprogram.com/wiki/CFG_File_Documentation ) both of which are either outdated or im looking at the wrong file type. When i open the .cfg file i dont see the fuelconsumption=? at all. the following is what i see and any help at all would be awesome.

PROPELLANT

{

name = LiquidFuel

ratio = 1

DrawGauge = True

}

PROPELLANT

{

name = IntakeAir

ratio = 15

}

atmosphereCurve

{

key = 0 1200

key = 0.3 2500

key = 1 800

}

velocityCurve

{

key = 0 0.5 0 0

key = 1000 1 0 0

key = 2000 0.5 0 0

key = 2400 0 0 0

}

Try looking for the line that says the Isp of the engine. Just increase that a bit and the fuel consumption should be lowered.

Well after a couple guess and checks the atmosphereCurve variables affect the isp; the higher the numbers the more efficient the engine becomes
