I have a Mallory Hyfire box that pulls timing automatically when the nitrous is activated. I just disabled the solenoids and type in the amount of timing i want to be pulled. As soon as the throttle switch makes it pulls the timing out and im good. Adjusting the timing is as easy as pushing the buttons on the boxes keypad. I love that box. I think I will redo my setup where the timing retard is activated as soon as i shift out of 1st gear,to help retain all my power for the launch. Im trying to improve my 60',leaving with lazy timing definitely wont help :lol:
