    Default launch retard using 6al and 8975 retard box

    hi I have 383 with one stage of nitrous with digi-set timer set .3 to come on.
    I have 6al with 8975 im using the first stage to pull 8*.
    I was wondering if I can use a digi set timer on/off delay relay to activate a second stage of retard lets say when nitrous activates and take 5* for x.x amount of time then turn off.
    is this poor man launch

    Add another delay timer and relay to your 2nd second retard trigger wire.

    I looked cant find anything on diagram on how to do it.
    also I wanted a delay switch but also to be able to turn it off at a desired time so im not taking additional timing thru out the whole run!
