Welcome, if you're asking for left foot braking enabling in EDC15 you can just search " 100 1 1200 " in 16 bit decimal LOHI format. Change the "1" to a "0". If you're having trouble just ask.
There are a few tools which can do the immo defeat for you or you can always do it manually. Just search this forum for solutions
Would be a good idea to check out the S4TuningWiki as well.
