I'm about to upgrade my ignition to a programable msd 6 al2. It has a built in 2 step. I'm thinking of connecting it to my line lock switch and using a double throw relay to disengage the nitrous circuit while the line lock is on. I will have another switch connected to the line lock that will turn off the 2step for burning out. I'm thinking about setting the 2step rpm limit to 2000-2500rpm since my nitrous and water/meth kicks on at 2800rpm. I'm thinking that this will allow me to peg the gas to the floor and having the line lock hold the car till I let off the button. Does this sound safe?
