i've got a question, i've got a msd 3 step launch control attached to msd 7al2. this is how i do my launch..: first i press the clutch, press button, floor the gas and release the clutch and go!

the problem is i will try preloading, so i pre stage, pull the e-brake, release the clutch till i feel like its dipping, release the the e -brake a little bit to stage, then pull e-brake, press the button(for launch control) and floor the gas BUT the rev limiter won't work! sometimes, it works but i can't let the clutch loose to much because it disengages... what seems to be the problem?

i don't have a line lock or anything.. my guess is that the higher i release the clutch pedal the clutch switch disengages therefore disengages the rev limit. how can i fix this?
