does the NX controller unit do spark timing retard? I don't use a controller unit like that.. so I am unaware. Instead I have my MSD Digital-6 ignition box tied into the nitrous wires, so when I hit the button, it signals the msd box to delay timing 4 deg (100 shot) or 6 deg(150 shot).
Figured I would mention it to you, but you probably already knew to retard timing 2 degrees for each 50 hp shot you are spraying.
